Resolution of symptoms of rectal prolapse after repair of vaginal prolapse: A report of two cases

Pelvic organ prolapse (POP) is a very common problem that can affect any aspect of the pelvic floor. Often, vaginal and rectal prolapse occur simultaneously. Prior case reports have suggested resolution of symptoms of rectal prolapse in those with concomitant rectal and vaginal prolapse; however, the overall body of evidence is limited. We present the cases of two patients who had complete resolution of their symptoms of rectal prolapse after repair of a concomitant vaginal prolapse. Both patients underwent a traditional rectocele repair and perineoplasty, and subsequently reported complete resolution of their symptoms of rectal prolapse, which persisted at their six-month post-operative visits. The second patient ultimately canceled a previously scheduled rectopexy with colorectal surgery. Perhaps a rectocele repair with perineoplasty is limiting rectal mobility, and therefore eliminating its ability to prolapse or intussuscept and cause bothersome symptoms. We suggest that those with concomitant vaginal and rectal prolapse desiring corrective surgery first undergo a less invasive vaginal repair. Post-operative re-evaluation of the symptoms rectal prolapse might then demonstrate that a more invasive rectal prolapse repair, which may involve a colon resection and prolonged hospital stay, was not in fact needed. Further prospective and randomized study is needed to determine the long-term outcomes of concomitant rectal and vaginal prolapse in those who first undergo a vaginal repair.

Long-term continuations rate of ring pessary use for symptomatic pelvic organ prolapse

PURPOSE

To evaluate long-term continuation rates, adverse events of ring pessary use at a minimum of 5 years follow-up, and factors associated with discontinuation in symptomatic pelvic organ prolapse (POP).

METHODS

Women with symptomatic POP who were treated with vaginal ring pessary and had successful fittings were included. Adverse events and reasons for discontinuation of pessary use were recorded. Patients who were lost to follow-up were defined as discontinuation.

RESULTS

During 12 year-period, 239 of 329 POP patients (72.6%) had successful fittings with ring pessary. The mean age was 67.8 ± 8.9 years (range 27-86) and 70% of patients had advanced stage. The cumulative probability of continued ring pessary use was 84.1%, 64.4%, 49.3%, and 33.5%, at 1, 3, 5, and 10 years, respectively. Most common reason for discontinuation was frequent expulsion (21.6%), followed by vaginal erosion (16.5%), no prolapse improvement (12.4%), and inability or inconvenience to do self-care (9.3%). However, 9 patients (9.3%) had improvement of prolapse and were able to discontinue pessary insertion. Age above 70 years, wide introitus, and incapability of self-care are independent factors associated with long-term discontinuation. Adverse events occurred in 23.4% of patients, 18.8% of them had vaginal erosion, 11.7% vaginal discharge/infection, and 18.4% de novo SUI. However, no statistical significance existed between those who continued and discontinued pessary use due to these adverse events.

CONCLUSION

Ring pessary is an effective treatment in symptomatic POP, with acceptable long-term continuation rates and minor adverse events. Self-care of pessary is very important aiming to minimize adverse events. Advanced age, wide introitus and incapability of self-care were associated factors for long-term discontinuation.

Defecatory dysfunction and anal incontinence symptoms among women with pelvic organ prolapse: 5-year retrospective study in a tertiary center

OBJECTIVE

To investigate the prevalence of DD and AI with POP symptoms in females attending a urogynecology clinic, and to identify factors associated with DD and AI in POP symptoms patients.

METHODS

Computer-based medical records of women with POP symptoms attending a urogynecology clinic in a referral tertiary center between January 2016 and December 2020 were reviewed. Demographic data were collected. Selected defecatory dysfunction (DD) and anal incontinence (AI) were recorded. The associations between patient characteristics, site and severity of prolapse, and DD and AI symptoms in POP patients were investigated for identified associated factors.

RESULTS

The mean age of the 754 participants was 65.77 ± 9.44 years. Seven hundred and fifteen (94.83%) were menopause. The prevalence of DD and AI in patients with POP symptoms was 44.03% (332/754) and 42.04% (317/754) according to the PFBQ and medical history records, respectively. Advanced posterior wall prolapse (OR 1.59, 95% CI 1.10-2.30) and wider GH (OR1.23, 95% CI 1.05-1.43) were identified as risk factors for DD by multivariate analysis. Additionally, single-compartment prolapse (OR 0.4, 95% CI 0.21-0.76) and a stronger pelvic floor muscle assessed with brink score (OR 0.94, 95% CI 0.88-0.98) are protective factors for AI.

CONCLUSION

DD and AI are prevalent among women with POP symptoms who visit a urogynecology clinic. DD should be evaluated in women with POP symptoms especially in women with increased genital hiatus and point Ap beyond the hymen. To prevent AI, women with POP should be encouraged to perform pelvic floor muscle training in order to increase pelvic floor muscle strength.

The effect of advanced age on peri- and post-operative complications following pelvic floor repair surgeries

OBJECTIVES

To assess whether advanced age is a risk factor for complications following pelvic organ prolapse (POP) repair surgeries using the Clavien-Dindo classification system.

METHODS

In this retrospective cohort study, 260 women who had undergone POP repair surgery at the Soroka University Medical Center (SUMC) between the years 2014-2019 were included. A univariate analysis was conducted to compare the demographical, clinical, obstetrical and operative characteristics of patients by age group (younger or older than 70 years). We performed a similar analysis to assess for the possible association between several variables and post-operative complications. Variables that were found to be associated with post-operative complications (P < 0.2) were included in a multivariate analysis along with advanced age.

RESULTS

During the 12 months follow-up period, more than half of the women had experienced at least one post-operative complication. Minor complications (grades 1-2 according to the Clavian-Dindo classification system) were the most common. One woman had died during the follow-up period, and none had experienced organ failure (grade 4). Hysterectomy, as part of POP surgery, was found to be significantly associated with post-operative complications. Additionally, grandmultiparity (> 5 births) showed a tendency towards an increased risk for post-operative complications, however this reached only borderline significance. We found no association between advanced age and post-operative complications.

CONCLUSIONS

POP repair surgeries are safe for women of all ages. Major complications (grades 3-5) are rare in all age groups. Although advanced age was associated with a higher prevalence of comorbidity and a higher grade of prolapse, no significant difference in the post-operative complications was found between age groups. Concomitant hysterectomy at the time of POP repair surgery is a risk factor for post-operative complications.

Pre-operative Prolapse Phenotype is Predictive of Surgical Outcome with Minimally Invasive Sacrocolpopexy

BACKGROUND

The gold standard treatment for advanced pelvic organ prolapse is sacrocolpopexy. However, the pre-operative features of prolapse that predict optimal outcomes are unknown.

OBJECTIVES

We aimed to develop a clinical prediction model that uses pre-operative scores on the Pelvic Organ Prolapse Quantification examination to predict outcomes after minimally invasive sacrocolpopexy for stages 2, 3, and 4 uterovaginal prolapse and vaginal vault prolapse.

STUDY DESIGN

A two-institution database of pre- and post-operative variables from 881 cases of minimally invasive sacrocolpopexy was analyzed. Data from patients were analyzed in four groups: stage 2 uterovaginal prolapse, stage 3-4 uterovaginal prolapse, stage 2 vaginal vault prolapse, and stage 3-4 vaginal vault prolapse. Unsupervised machine learning was used to identify clusters and investigate associations between clusters and outcome. The K-means clustering analysis was performed with pre-operative Pelvic Organ Prolapse Quantification points and stratified by prior hysterectomy status. The "optimal" surgical outcome was defined as post-operative Pelvic Organ Prolapse Quantification stage <2. Demographic variables were compared by cluster with Student's t-test and Chi-squared tests. Odds ratios were calculated to determine whether clusters could predict the outcome. Age at surgery, body mass index, and prior prolapse surgery were used for adjusted odds ratios.

RESULTS

Five statistically distinct prolapse clusters (phenotypes C, A, A>P, P, and P>A) were found. These phenotypes reflected the predominant region of prolapse (apical, anterior, or posterior) and whether or not support was preserved in the non-predominant region. Phenotype A (anterior compartment prolapse predominant, posterior support preserved) was found in all four groups of patients and was considered the reference in analysis. In 111 patients with stage 2 uterovaginal prolapse, phenotypes A and A>P (greater anterior prolapse than posterior prolapse) were found, and patients with phenotype A were more likely than those with phenotype A>P to have an optimal surgical outcome. In 401 patients with stage 3-4 uterovaginal prolapse, phenotypes C (apical compartment predominant, prolapse in all compartments), A, and A>P were found, and patients with phenotype A>P were more likely than those with phenotype A to have ideal surgical outcome. In 72 patients with stage 2 vaginal vault prolapse, phenotypes A, A>P, and P (posterior compartment predominant, anterior support preserved) were found, and those with phenotype A>P were less likely to have an ideal outcome than patients with phenotype A. In 297 patients with stage 3-4 vaginal vault prolapse, phenotypes C, A, and P>A (prolapse greater in posterior compartment than in anterior) were found, but there were no significant differences in rate of ideal outcome between phenotypes.

CONCLUSIONS

Five anatomic phenotypes based on pre-operative Pelvic Organ Prolapse Quantification scores were present in patients with stages 2 and 3-4 uterovaginal prolapse and vaginal vault prolapse. These phenotypes are predictive of surgical outcome after minimally invasive sacrocolpopexy. Further work needs to confirm the presence and predictive nature of these phenotypes. Additionally, whether the phenotypes represent a progression of prolapse or discrete prolapse presentations resulting from different anatomic and life course risk profiles is unknown. These phenotypes may be useful in surgical counseling and planning.

Self-care of vaginal pessary for pelvic organ prolapse: a systematic review and meta-analysis

INTRODUCTION

There is no evidence about the efficacy of self-care of vaginal pessary in women with symptomatic pelvic organ prolapse (POP). The aim of this systematic review and meta-analysis is to assess the adherence to pessary treatment among women who engage in self-management of their pessary.

METHODS

We performed a systematic review and meta-analysis, according to PRISMA 2020 guidelines, and selected seven publications for inclusion in the analysis.

RESULTS

Pooled continuation rate of self-cared vaginal pessary was the 76% (95%CI: 66-85%) with a I2-test of 93.3% (p < 0.001). Pooled conversion to POP surgery was the 12% (95%CI: 1-23%) with a I2-test of 96% (p < 0.001). Continuation rate was not statistically different between women who were treated by self-care and non-self-care management of vaginal pessary (RR 1.11, 95%CI 0.96-1.27; p = 0.15), with a related I2-test of 37% (p = 0.21).

CONCLUSION

Self-care vaginal pessary management presented a high continuation rate in women affected by pelvic organ prolapse at a long follow-up. The rate of conversion to surgical management of POP was low. No significant difference in continuation rate were highlighted between women who adopted the self-care or the clinical-based management of pessary.

A randomized, prospective, controlled study comparing uterine preserving laparoscopic lateral suspension with mesh versus laparoscopic sacrohysteropexy in the treatment of uterine prolapse

OBJECTIVES

Pelvic organ prolapse (POP) significantly affects women's quality of life, occurring in 20-30% of females aged over 20 globally. With aging populations, demand for pelvic reconstructive surgery is rising. Patients seek anatomical restoration while preserving uterus and sexual function. Sacrohysteropexy is the gold standard for apical prolapse, but carries risks. Lateral suspension, offers safer apical and anterior correction especially for obese, sexually active women. Our prospective study compares laparoscopic sacrohysteropexy and lateral suspension objectively and subjectively.

STUDY DESIGN

The study included patients who had laparoscopic lateral suspension (n = 22) or laparoscopic sacrohysteropexy (n = 22) for symptomatic stage 2 apical prolapse. Groups randomized with using block design. Anatomical cure was based on measurements taken by the same physician, unaware of intervention, before and at 12 months using POP-Q score. Pelvic floor ultrasound also used for objective rates. Subjective comparison used Prolapse Quality of Life (P-QoL), Pelvic Organ Prolapse-Symptom Score (POP-SS), Female Sexual Function Index (FSFI), Visual Analog Score (VAS), and Michigan Incontinence Severity Index (M-ISI).

RESULTS

Age, BMI, parity, menopause, sexual activity, complications, showed no significant difference between groups (p > 0.05). Surgical procedure duration significantly varied between groups lateral suspension group was shorter. There was no significant difference in post operative complications. No significant differences in posterior/enterocele stages.) Anterior staging showed no significant difference in sacrouteropexy (p = 0.130), but significant difference in lateral suspension group (p < 0.001). No significant differences in pre-op and post-op PQOL, POP-SS, FSFI, and M-ISI scores between the two groups.

CONCLUSION

Both methods effectively managed apical prolapse with similar outcomes. Objective measurements showed lateral suspension's superiority in reducing bladder descent.

Frequency of cul-de-sac obliteration in surgery for pelvic organ prolapse: a retrospective analysis

INTRODUCTION AND HYPOTHESIS

We aimed to clarify the frequency of cul-de-sac obliteration in patients undergoing POP surgery.

METHODS

We retrospectively reviewed patients who underwent laparoscopic POP surgery at our hospital between April 2017 and September 2021.

RESULTS

In total, 191 cases were included in the analysis. Ten patients (5.2%) had cul-de-sac obliteration. No difference in age (73 years vs. 72 years, P = 0.99), parity (2 vs. 2, P = 0.64), or body mass index (BMI) (25.7 kg/m2 vs. 24.7 kg/m2, P = 0.34) was observed between the cul-de-sac obliteration and normal groups. No significant differences were observed in the rate of previous abdominal surgery (50.0% vs. 32.6%, P = 0.46), rate of POP - quantification system (POP-Q) ≥ 2 posterior prolapse (40.0% vs. 46.4%, P = 0.98), and effect of defecation symptoms on the prolapse quality of life (p-QOL) score (vaginal bulge emptying bowels: 2.5 vs. 3.5, P = 0.15; empty bowel feeling: 3 vs. 3, P = 0.72, constipation: 3.5 vs. 3, P = 0.58; straining to open bowels: 3.5 vs. 3, P = 0.82; empty bowels with fingers: 1 vs. 1, P = 0.55) between the cul-de-sac obliteration and normal groups. Multivariate analysis of risk factors for the cul-de-sac obliteration was performed for age, number of births, previous abdominal surgery, and presence of rectocele; however no significant risk factors were extracted.

CONCLUSION

Predicting cul-de-sac obliteration preoperatively in patients undergoing POP surgery based on age, number of previous surgeries, previous abdominal surgeries, rectocele, and defecation symptoms is difficult.

Prediction of successful revision surgery for mesh-related complaints after inguinal hernia and pelvic organ prolapse repair

PURPOSE

With this retrospective case series, we aim to identify predictors for reduction of pain after mesh revision surgery in patients operated for inguinal hernia or pelvic organ prolapse with a polypropylene implant. Identifying these predictors may aid surgeons to counsel patients and select appropriate candidates for mesh revision surgery.

METHODS

Clinical records before and after mesh revision surgery from 221 patients with chronic postoperative inguinal pain (CPIP) and 59 patients with pain after pelvic organ prolapse (POP) surgery were collected at two experienced tertiary referral centers. Primary outcome was patient reported improvement of pain after revision surgery. A multivariable logistic regression model was used to specify predictors for pain reduction.

RESULTS

The multivariable logistic regression was performed for each patient group separately. Patients with CPIP had higher chances of improvement of pain when time between mesh placement and mesh revision surgery was longer, with an OR of 1.19 per year. A turning point in chances of risks and benefits was demonstrated at 70 months, with improved outcomes for patients with revision surgery ≥ 70 months (OR 2.86). For POP patients, no statistically significant predictors for reduction of pain after (partial) removal surgery could be identified.

CONCLUSION

A longer duration of at least 70 months between implantation of inguinal mesh and revision surgery seems to give a higher chance on improvement of pain. Caregivers should not avoid surgery based on a longer duration of symptoms when an association between symptoms and the location of the mesh is found.

Robot-assisted radical nephroureterectomy for right renal pelvic tumor post sacrocolpopexy with mesh: A case report

INTRODUCTION

Robot-assisted nephroureterectomy for upper tract urothelial carcinoma has been increasingly performed as a minimally invasive procedure recently. However, there are concerns regarding its adoption in highly complex cases with dense adhesions.

PRESENTATION OF CASE

An 86-year-old woman presented to our hospital with gross hematuria one year after having undergone robot-assisted sacrocolpopexy using a mesh for pelvic organ prolapse. Cystoscopy revealed hematuria from the right ureteral orifice. Computed tomography suggested right hydronephrosis; retrograde pyelography showed a defect in the right renal pelvis with class V urine cytology of the urine from the right kidney. Based on these findings, a right renal pelvic tumor was diagnosed, and robot-assisted nephroureterectomy was performed. The patient was discharged on postoperative day 7 without complications.

DISCUSSION

To the best of our knowledge, this is the first case report in which robot-assisted radical nephroureterectomy was performed after robot-assisted sacrocolpopexy with a mesh. Dense tissue adhesions are encountered not only between the bladder and the anterior vaginal wall but also around the right ureter in the pelvis. In this case, dense adhesions were confirmed around the right ureter in the pelvis.

CONCLUSION

Robot-assisted nephroureterectomy may be considered an option for minimally invasive surgery in cases with a history of pelvic organ prolapse surgery using mesh.

The minimally invasive sacrospinous fixation under visual guidance: An anatomical study

OBJECTIVE

Sacrospinous fixation is the gold standard procedure for management of apical pelvic organ prolapse by the vaginal route. However, there may be a relevant risk of neurovascular injury due to the proximity of neurovascular structures. We propose an anatomical study concerning the sacrospinous ligament with a new innovative minimally invasive technology using both a suture capturing device and a chip-on-the-tip endoscope to perform sacropinous fixation.

STUDY DESIGN

Bilateral sacrospinous fixation was performed in three female cadavers, in the course of the anatomical study conducted with a specific device (the Suture Capturing I Stitch™ Device) under real time visual guidance with a chip-on -the-tip endoscope, the NanoScope™ system.

RESULTS

Identification of ischial spine and sacrospinous ligament as well as feasibility of sacrospinous fixation under NanoScope™ control were always possible on both sides.

CONCLUSIONS

This new innovative minimally invasive technology using both a suture capturing device and a chip-on-the-tip endoscope is relevant and could be an advantage in terms of safety and better placement of the suture on the sacrospinous ligament.

Long-Term Mesh Exposure 5 Years Following Minimally Invasive Total Hysterectomy and Sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

The objective was to assess long-term mesh complications following total hysterectomy and sacrocolpopexy.

METHODS

In this second extension study, women from a multicenter randomized trial were followed for more than 36 months after surgery. Owing to COVID-19, participants were assessed through either in-person visits or telephone questionnaires. The primary outcome was the incidence of permanent suture or mesh exposure. Secondary outcomes included surgical success and late adverse outcomes.

RESULTS

Out of the 200 initially enrolled participants, 82 women took part in this second extension study. Among them, 46 were in the permanent suture group, and 36 in the delayed absorbable group. The mean follow-up duration was 5.3 years, with the cumulative mesh or suture exposure of 9.9%, involving 18 cases, of which 4 were incident cases. Surgical success after more than 5 years stood at 95%, with few experiencing bothersome bulge symptoms or requiring retreatment. No serious adverse events occurred, including mesh erosion into the bladder or bowel. The most common adverse events were vaginal pain, bleeding, dyspareunia, and stress urinary incontinence, with no significant differences between suture types.

CONCLUSION

The study found that mesh exposure risk gradually increased over time, reaching nearly 10% after more than 5 years post-surgery, regardless of suture type. However, surgical success remained high, and no delayed serious adverse events were reported.

Exploring risk factors of pelvic organ prolapse at eastern of Democratic Republic of Congo: a case-control study

BACKGROUND

Pelvic organ prolapse is a common debilitating condition worldwide. Despite surgical treatment, its recurrence can reach up to 30%. It has multiple risk factors, some of which are particular for a low-resource settings. The identification these factors would help to devise risk models allowing the development of prevention policies. The objective of this study was to explore risk factors for pelvic organ prolapse in a population in eastern Democratic Republic of Congo (DRC).

METHODS

This was an unmatched case-control study conducted between January 2021 and January 2022. The sample size was estimated to be a total of 434 women (217 with prolapse as cases and 217 without prolapse as controls). Data comparisons were made using the Chi-Square and Student T tests. Binary and multivariate logistic regressions were used to determine associated factors. A p < 0.05 was considered significant.

RESULTS

Variables identified as definitive predictors of pelvic organ prolapse included low BMI (aOR 2.991; CI 1.419-6.307; p = 0.004), home birth (aOR 6.102; CI 3.526-10.561; p < 0.001), family history of POP (aOR 2.085; CI 1.107-3.924; p = 0.023), history of birth without an episiotomy (aOR 3.504; CI 2.031-6.048; p = 0), height ≤ 150 cm (aOR 5.328; CI 2.942-9.648; p < 0.001) and history of giving birth to a macrosomic baby (aOR 1.929; IC 1.121-3.321; p = 0.018).

CONCLUSIONS

This study identified that Body Mass Index and birth-related factors are definitive predictors of pelvic organ prolapse in a low-resource setting. These factors are potentially modifiable and should be targeted in any future pelvic organ prolapse prevention policy. Additionally, there seems to be a genetic predisposition for prolapse, which warrants further assessment in specifically designed large scale studies.

Laparoscopic versus Vaginal Uterosacral Ligament Suspension in Women with Pelvic Organ Prolapse: A Systematic Review and Meta-analysis of the Literature

OBJECTIVE

Uterosacral ligament suspension (USLS) is one of the most frequently used operations for the restoration of apical support in women with uterovaginal prolapse. However, existing studies are inconclusive as to whether and which surgical access route is superior. The aim of the present meta-analysis is tentatively to compare the efficiency and the postoperative complications of laparoscopic USLS (L-USLS) and vaginal USLS (V-USLS), highlighting that current evidence remains inconclusive regarding the superiority of either surgical access route.

DATA SOURCES

We performed a systematic literature review of 5 major databases (Medline, Scopus, Google Scholar Cochrane Central Register of Controlled Trials and Clinicaltrials.gov) from inception till April 2023.

METHODS OF STUDY SELECTION

No language restrictions were applied. All comparative studies that compared L-USLS and V-USLS for the management of women with uterovaginal prolapse were included.

TABULATION, INTEGRATION, AND RESULTS

Data from 6 retrospective cohort studies on 856 patients were extracted and analyzed. The methodological quality of the included studies was assessed using the risk of bias in nonrandomized studies of interventions tool and ranged between moderate to serious. The pooled results suggest that L-USLS was associated with a potentially decreased incidence of ureteral compromise (odds ratio [OR], 0.19; 95% confidence interval [CI] 0.04-0.89; p = .04) and seemingly lower objective (OR 0.47; 95% CI 0.23-0.97; p = .04) and subjective recurrence rates (OR 0.46; 95% CI 0.23-0.92; p = .03). There were no significant differences between the rates of postoperative pain from USLS sutures, postoperative pelvic hematomas, the suture exposure/granulation tissue formation, and the prolapse recurrence retreatment among the 2 groups.

CONCLUSION

The present meta-analysis indicates that L-USLS is possibly associated with significantly fewer ureteral compromise rates and decreased subjective and objective recurrences rates compared to V-USLS. Nevertheless, given the limitations in data quality and heterogeneity of the included studies, these findings should be interpreted with caution. Large-scale randomized studies are essential to more definitively determine the relative merits of the laparoscopic versus vaginal approach.

Increased extracellular matrix stiffness regulates myofibroblast transformation through induction of autophagy-mediated Kindlin-2 cytoplasmic translocation

The extracellular matrix (ECM) mechanical properties regulate biological processes, such as fibroblast-myofibroblast transformation (FMT), which is a crucial component in pelvic organ prolapse (POP) development. The 'Kindlin-2' protein, expressed by fibroblasts, plays an important role in the development of the mesoderm, which is responsible for connective tissue formation; however, the role of Kindlin-2 in FMT remains to be explored. In this study, we aimed to explore the role of Kindlin-2 in FMT as it relates to POP. We found that ECM stiffness induces autophagy to translocate Kindlin-2 to the cytoplasm of L929 cells, where it interacts with and degrades MOB1, thereby facilitating Yes-associated protein (YAP) entry into the nucleus and influencing FMT progression. Stiffness-induced autophagy was inhibited when using an autophagy inhibitor, which blocked the translocation of Kindlin-2 to the cytoplasm and partially reversed high-stiffness-induced FMT. In patients with POP, we observed an increase in cytoplasmic Kindlin-2 and nuclear YAP levels. Similar changes in vaginal wall-associated proteins were observed in a mouse model of acute vaginal injury. In conclusion, Kindlin-2 is a key gene affecting ECM stiffness, which regulates FMT by inducing autophagy and may influence the development of POP.

Effect of Vaginal Microecological Alterations on Female Pelvic Organ Prolapse

INTRODUCTION AND HYPOTHESIS

The objective was to investigate the correlation between endogenous vaginal microecological alterations and female pelvic organ prolapse (POP).

METHODS

Patients who underwent vaginal hysterectomy were retrospectively analyzed as the POP group (n = 30) and the non-POP group (n = 30). The vaginal microbial metabolites and enzyme levels were tested using the dry chemoenzymatic method. The mRNA and protein expression were tested using real-time quantitative PCR and immunohistochemistry. SPSS version 25.0 and GraphPad Prism 8.0 were performed for statistical analysis.

RESULTS

Compared with the non-POP group, the vaginal pH, H2O2 positivity and leukocyte esterase positivity were higher in patients with POP (all p < 0.05). Further analysis showed that patients with pelvic organ prolapse quantification (POP-Q) stage IV had higher rates of vaginal pH, H2O2 positivity and leukocyte esterase positivity than those with POP-Q stage III. Additionally, the mRNA expression of decorin (DCN), transforming growth factor beta 1 (TGF-β1), and matrix metalloproteinase-3 (MMP-3) in uterosacral ligament tissues were higher, whereas collagen I and III were lower. Similarly, the positive expression of MMP-3 in uterosacral ligament tissue was significantly upregulated in the POP group compared with the non-POP group (p = 0.035), whereas collagen I (p = 0.004) and collagen III (p = 0.019) in uterosacral ligament tissue were significantly downregulated in the POP group. Correlation analysis revealed that there was a significant correlation between vaginal microecology and collagen metabolism. In addition, MMP-3 correlated negatively with collagen I and collagen III (p = 0.002, r = -0.533; p = 0.002, r = -0.534 respectively), whereas collagen I correlated positively with collagen III (p = 0.001, r = 0.578).

CONCLUSIONS

Vaginal microecological dysbiosis affects the occurrence of female POP, which could be considered a novel therapeutic option.

A randomized clinical trial comparing internal and external pessaries in the treatment of pelvic organ prolapse in postmenopausal women: A pilot study

INTRODUCTION AND HYPOTHESIS

Internal vaginal pessary is among the leading treatments for pelvic organ prolapse (POP); however, it has a high adverse event rate. An external pessary was recently developed as an alternative. The study's objective was to compare the efficacy of external and internal pessaries in treating POP in postmenopausal women.

METHODS

This parallel randomized (1:1 ratio) open-blind study included 40 symptomatic women with stage 2 or 3 POP. They were randomized into two groups: group 1 (internal pessary) and group 2 (external pessary) (n = 20 in each); and evaluated at the start of and 3 months after the treatment. Statistical analysis was performed to compare the results within and between the groups before and after the 3-month treatment.

RESULTS

The groups were homogeneous, except for the variables previous pregnancies (p = 0.030) and POP-Q score of apical prolapse (p = 0.023) whose values were higher in group 2. A significant improvement in quality of life was observed in both groups after 3 months of follow-up; however, internal pessaries were found to be more effective (p < 0.001). In group 1 there were differences between the initial and final POP-Q scores of anterior (0.004) and apical prolapse (p = 0.005). The complication rate associated with internal pessary use was high (p = 0.044).

CONCLUSIONS

The present data suggested that external pessaries have a similar effect to internal ones for the treatment of POP and improvement of the quality of life of postmenopausal women.

Postoperative complications and unanticipated healthcare encounters following mini-laparotomy vs. laparoscopic/robotic-assisted sacrocolpopexy: a comparative retrospective study

BACKGROUND

Pelvic organ prolapse is a debilitating condition impacting lives of millions of women worldwide. Sacrocolpopexy (SCP) is considered an effective and durable surgical technique for treatment of apical prolapse. The aim of this study was to compare short-term outcomes including postoperative complications and unanticipated healthcare encounters between patients who underwent SCP with a mini-laparotomy approach compared to patients treated with laparoscopic and robotic-assisted laparoscopic SCP.

METHODS

This was a retrospective cohort study including patients treated for apical prolapse at a university affiliated urogynecology practice. Patients over the age of 18 who underwent abdominal SCP between 2019 and 2023 were included. The cohort was formed into two groups: (1) Patients who underwent SCP through a mini-laparotomy incision (Mini-lap group); (2) Patients who underwent laparoscopic or robotic-assisted laparoscopic SCP (Lap/Robot group).

RESULTS

A total of 116 patients were included in the final analysis. Ninety patients underwent either laparoscopic or robotic-assisted SCP, whereas 26 patients underwent SCP with a mini-laparotomy approach. Study participants exhibited a mean age of 63.1 ± 10.3 years, mean body mass index (BMI) of 25.8 ± 4.9 Kg/m2, and 77.6% of them identified as Caucasian. Upon comparison of demographic and past medical history between groups there were no statistically significant differences in age, BMI, menopausal status, race, parity or comorbid conditions. Patients in the Mini-lap group were less likely to have undergone previous abdominal surgery (11.5% vs. 50.6%, p < 0.001) and had more severe apical prolapse (stage 4 prolapse, 40% vs. 21.2%, p < 0.001) than their counterparts in the Lap/robot group. Regarding intraoperative parameters, length of surgery was significantly shorter in the Mini-lap group compared to the Lap/robot group (97.3 ± 35.0 min vs. 242.0 ± 52.6 min, p < 0.001). When focusing on the primary outcome, postoperative complications within the first 30 days after surgery, there were no differences noted between groups. Additionally, the number of unanticipated healthcare encounters, such as phone calls, clinic visits, emergency department visits, urgent care visits, readmissions and reoperations were similar between groups.

CONCLUSIONS

Mini-laparotomy approach for SCP is safe with comparable intra- and postoperative complications, and unanticipated healthcare encounters compared to conventional minimally invasive methods.

Anterior-apical Transvaginal Mesh (Calistar-S) for Treatment of Advanced Urogenital Prolapse: Surgical and Functional Outcomes at 1 Year

INTRODUCTION AND HYPOTHESIS

Calistar-S is a single-incision synthetic mesh kit that addresses apical and anterior compartment prolapse. The aims of this study were to evaluate the short-term objective and subjective outcomes at the 1-year follow-up. The secondary objectives were to evaluate quality of life and lower urinary tract symptoms (LUTS) outcomes, as well as surgical complications.

METHODS

Records of 108 patients with symptomatic advanced pelvic organ prolapse (stages III and IV) who underwent prolapse surgery using the Calistar-S system from June 2018 to August 2022 were reviewed. The primary outcome was the objective cure of anterior and apical prolapse < stage 1, and the subjective cure was the negative response to questions 2 and 3 of the Pelvic Organ Prolapse Distress Inventory-6. Secondary outcomes measured quality of life, the presence of lower urinary tract symptoms, and complications.

RESULTS

A total of 101 patients were evaluated. The overall objective cure rate is 97% and the subjective cure rate is 92.1%. Good outcomes were seen in all three compartments. Secondary outcomes show significant improvement in all validated questionnaires. Persistence and de novo urinary incontinence were 15.2% and 18.2% post-operatively. There is one case of bladder injury and one case of vaginal mesh exposure.

CONCLUSIONS

The Calistar-S System is a safe and efficient method for treating advanced-stage POP. We observed good anatomical results and subjective relief with a minimal complication rate. LUTS have also been positively affected, showing a high success rate. Additional studies are needed to establish the long-term efficacy of this system.

Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice

Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh. Each recommendation for practice was allocated a grade (A,B or C; or expert opinion (EO)), which depends on the level of evidence (clinical practice guidelines).

PREOPERATIVE PATIENTS' INFORMATION

Each patient must be informed concerning the risks associated with POP surgery (EO).

HEMORRHAGE, HEMATOMA

Vaginal infiltration using a vasoconstrictive solution is not recommended during POP surgery by the vaginal route (grade C). The placement of vaginal packing is not recommended following POP surgery by the vaginal route (grade C). During laparoscopic sacral colpopexy, when the promontory seems highly dangerous or when severe adhesions prevent access to the anterior vertebral ligament, alternative surgical techniques should be discussed per operatively, including colpopexy by lateral mesh laparoscopic suspension, uterosacral ligament suspension, open abdominal mesh surgery, or surgery by the vaginal route (EO).

BLADDER INJURY

When a bladder injury is diagnosed, bladder repair by suturing is recommended, using a slow resorption suture thread, plus monitoring of the permeability of the ureters (before and after bladder repair) when the injury is located at the level of the trigone (EO). When a bladder injury is diagnosed, after bladder repair, a prosthetic mesh (polypropylene or polyester material) can be placed between the repaired bladder and the vagina, if the quality of the suturing is good. The recommended duration of bladder catheterization following bladder repair in this context of POP mesh surgery is from 5 to 10 days (EO).

URETER INJURY

After ureteral repair, it is possible to continue sacral colpopexy and place the mesh if it is located away from the ureteral repair (EO).

RECTAL INJURY

Regardless of the approach, when a rectal injury occurs, a posterior mesh should not be placed between the rectum and the vagina wall (EO). Concerning the anterior mesh, it is recommended to use a macroporous monofilament polypropylene mesh (EO). A polyester mesh is not recommended in this situation (EO).

VAGINAL WALL INJURY

After vaginal wall repair, an anterior or a posterior microporous polypropylene mesh can be placed, if the quality of the repair is found to be satisfactory (EO). A polyester mesh should not be used after vaginal wall repair (EO).

MESH INFECTION (ABSCESS, CELLULITIS, SPONDYLODISCITIS)

Regardless of the surgical approach, intravenous antibiotic prophylaxis is recommended (aminopenicillin + beta-lactamase inhibitor: 30 min before skin incision +/- repeated after 2 h if surgery lasts longer) (EO). When spondylodiscitis is diagnosed following sacral colpopexy, treatment should be discussed by a multidisciplinary group, including especially spine specialists (rheumatologists, orthopedists, neurosurgeons) and infectious disease specialists (EO). When a pelvic abscess occurs following synthetic mesh sacral colpopexy, it is recommended to carry out complete mesh removal as soon as possible, combined with collection of intraoperative bacteriological samples, drainage of the collection and targeted antibiotic therapy (EO). Non-surgical conservative management with antibiotic therapy may be an option (EO) in certain conditions (absence of signs of sepsis, macroporous monofilament polypropylene type 1 mesh, prior microbiological documentation and multidisciplinary consultation for the choice of type and duration of antibiotic therapy), associated with close monitoring of the patient.

BOWEL OCCLUSION RELATED TO NON-CLOSURE OF THE PERITONEUM

Peritoneal closure is recommended after placement of a synthetic mesh by the abdominal approach (EO).

URINARY RETENTION

Preoperative urodynamics is recommended in women presenting with urinary symptoms (bladder outlet obstruction symptoms, overactive bladder syndrome or incontinence) (EO). It is recommended to remove the bladder catheter at the end of the procedure or within 48 h after POP surgery (grade B). Bladder emptying and post-void residual should be checked following POP surgery, before discharge (EO). When postoperative urine retention occurs after POP surgery, it is recommended to carry out indwelling catheterization and to prefer intermittent self-catheterization (EO).

POSTOPERATIVE PAIN

Before POP surgery, the patient should be asked about risk factors for prolonged and chronic postoperative pain (pain sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Concerning the prevention of postoperative pain, it is recommended to carry out a pre-, per- and postoperative multimodal pain treatment (grade B). The use of ketamine intraoperatively is recommended for the prevention of chronic postoperative pelvic pain, especially for patients with risk factors (preoperative painful sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Postoperative prescription of opioids should be limited in quantity and duration (grade C). When acute neuropathic pain (sciatalgia or pudendal neuralgia) resistant to level I and II analgesics occurs following sacrospinous fixation, a reintervention is recommended for suspension suture removal (EO). When chronic postoperative pain occurs after POP surgery, it is recommended to systematically seek arguments in favor of neuropathic pain with the DN4 questionnaire (EO). When chronic postoperative pelvic pain occurs after POP surgery, central sensitization should be identified since it requires a consultation in a chronic pain department (EO). Concerning myofascial pain syndrome (clinical pain condition associated with increased muscle tension caused by myofascial trigger points), when chronic postoperative pain occurs after POP surgery, it is recommended to examine the levator ani, piriformis and obturator internus muscles, so as to identify trigger points on the pathway of the synthetic mesh (EO). Pelvic floor muscle training with muscle relaxation is recommended when myofascial pain syndrome is associated with chronic postoperative pain following POP surgery (EO). After failure of pelvic floor muscle training (3 months), it is recommended to discuss surgical removal of the synthetic mesh, during a multidisciplinary discussion group meeting (EO). Partial removal of synthetic mesh is indicated when a trigger point is located on the pathway of the mesh (EO). Total removal of synthetic mesh should be discussed during a multidisciplinary discussion group meeting when diffuse (no trigger point) chronic postoperative pain occurs following POP surgery, with or without central sensitization or neuropathic pain syndromes (EO).

POSTOPERATIVE DYSPAREUNIA

When de novo postoperative dyspareunia occurs after POP surgery, surgical removal of the mesh should be discussed (EO).

VAGINAL MESH EXPOSURE

To reduce the risk of vaginal mesh exposure, when hysterectomy is required during sacral colpopexy, subtotal hysterectomy is recommended (grade C). When asymptomatic vaginal macroporous monofilament polypropylene mesh exposure occurs, systematic imaging is not recommended. When vaginal polyester mesh exposure occurs, pelvic +/- lumbar MRI (EO) should be used to look for an abscess or spondylodiscitis, given the greater risk of infection associated with this type of material. When asymptomatic vaginal mesh exposure of less than 1 cm2 occurs in a woman with no sexual intercourse, the patient should be offered observation (no treatment) or local estrogen therapy (EO). However, if the patient wishes, partial excision of the mesh can be offered. When asymptomatic vaginal mesh exposure of more than 1 cm2 occurs or if the woman has sexual intercourse, or if it is a polyester prosthesis, partial mesh excision, either immediately or after local estrogen therapy, should be offered (EO). When symptomatic vaginal mesh exposure occurs, but without infectious complications, surgical removal of the exposed part of the mesh by the vaginal route is recommended (EO), and not systematic complete excision of the mesh. Following sacral colpopexy, complete removal of the mesh (by laparoscopy or laparotomy) is only required in the presence of an abscess or spondylodiscitis (EO). When vaginal mesh exposure recurs after a first reoperation, the patient should be treated by an experienced team specialized in this type of complication (EO).

SUTURE THREAD VAGINAL EXPOSURE

For women presenting with vaginal exposure to non-absorbable suture thread following POP surgery with mesh reinforcement, the suture thread should be removed by the vaginal route (EO). Removal of the surrounding mesh is only recommended when vaginal mesh exposure or associated abscess is diagnosed.

BLADDER AND URETERAL MESH EXPOSURE

When bladder mesh exposure occurs, removal of the exposed part of the mesh is recommended (grade B). Both alternatives (total or partial mesh removal) should be discussed with the patient and should be debated during a multidisciplinary discussion group meeting (EO).

Establishing a Rat Model of Pelvic Organ Prolapse with All Compartment Defects by Persistent Cervical Tension

INTRODUCTION AND HYPOTHESIS

We hypothesized that applying cervical suction and persistent tension can develop a novel and efficient rat model of pelvic organ prolapse.

METHODS

Fifteen rats underwent pilot testing to optimize the protocol. Sixteen rats were subjected to pelvic organ prolapse induction by cervical suction and constant traction, while five rats served as controls. The pelvic organ prolapse rats were assessed by a Rat Pelvic Organ Prolapse Quantification system at different time points, and their diet, urine, and stool were monitored for 21 days. The pelvic organ prolapse rats were also evaluated for urinary incontinence, urinary retention, leak point pressure, and vaginal histopathology at 21 days after operation.

RESULTS

This rat model demonstrated pelvic floor prolapse in anatomic level, as well as physiological variations (urine incontinence, urinary retention) and pathological changes (collagen fracture, decreased collagen density).

CONCLUSIONS

This is the first establishment of the pelvic organ prolapse rat model with all compartment defects, which provides a valuable tool for elucidating pelvic organ prolapse mechanisms and evaluating potential interventions.

Two-Year Preclinical Evaluation of Long-Term Absorbable Poly-4-hydroxybutyrate Scaffold for Surgical Correction of Pelvic Organ Prolapse

INTRODUCTION AND HYPOTHESIS

Fully absorbable implants may be an alternative to permanent meshes in the correction pf pelvic organ prolapse (POP) as they may reduce adverse events by promoting tissue regeneration and collagen metabolism. This study was aimed at evaluating the long-term host and biomechanical response to a fully absorbable poly-4-hydroxybutyrate (P4HB) scaffold in comparison with polypropylene (PP) mesh.

METHODS

Poly-4-hydroxybutyrate scaffold (n = 16) and PP mesh (n = 16) were surgically implanted in the posterior vaginal wall of parous female Dohne Merino sheep. Vaginal explants were evaluated in terms of gross necropsy, host response (immune response, collagen deposition, tissue regeneration), biomechanics, and degradation of P4HB at 12 and 24 months post-implantation.

RESULTS

Gross necropsy revealed no infection or fluid collection using P4HB or PP. At 12 months, exposures were observed with both P4HB (3 out of 8) and PP (4 out of 8), whereas at 24 months, exposures were observed only with PP (4 out of 8). The tensile stiffness of the P4HB explants was maintained over time despite complete absorption of P4HB. The collagen amount of the vaginal tissue after P4HB implantation increased over time and was significantly higher than PP at 24 months. P4HB scaffolds exhibited significantly lower myofibroblast differentiation than PP meshes at 24 months.

CONCLUSIONS

The P4HB scaffold allowed for gradual load transfer to the vaginal wall and resulted in mechanically self-sufficient tissue. P4HB scaffold had a more favorable host response than PP mesh, with higher collagen content, lower myofibroblastic differentiation, and no exposures at 24 months. P4HB scaffolds have potential as an alternative to permanent implants in treating POP.

Pubococcygeal Line Versus H-line as MR Defecography Reference for Bladder Descent

INTRODUCTION AND HYPOTHESIS

Magnetic resonance defecography imaging techniques have been used widely to study pelvic floor function and diagnose pelvic organ prolapse (POP). The aim of this study was to investigate the diagnostic accuracy of the H-line to detect bladder descent compared with the current landmark, the pubococcygeal line (PCL).

METHODS

In this retrospective cohort study, patients who underwent MR defecography in our medical center and were diagnosed with moderate to severe cystocele by radiological measurements were recruited. One rest image and one maximum evacuation image for each subject were used for the following measurements: bladder base perpendicular distance from the genital hiatus (GH), indicative of clinically significant bladder descent, PCL as the current radiological reference line, and the H-line, or minimal levator hiatus line, indicative of pelvic floor muscle and connective tissue support. Subjects were categorized as having clinically significant cystocele if the "bladder base" reached within 1 cm or lower of the GH (stage II or higher cystocele). A comparison was performed to assess differences and predictive capabilities of the reference lines relative to the GH measure.

RESULTS

Seventy subjects were included, 30 with clinically significant bladder descent based on distance to GH. Women with bladder descent were older (64.0 ± 11.8 vs 51.2 ± 15.6, p < 0.001), had increased parity (3 [1-7] vs 2 [0-5], p = 0.009), and had a bladder that descended lower than the H-line at rest (1.9 ± 0.5 vs 2.2 ± 0.4, p = 0.003) and evacuation (-2.4 ± 1.6 vs -0.7 ± 1.1, p < 0.001). Multivariate regression analysis confirmed that age, length of the H-line at evacuation, the perpendicular distances between the H-line and the lowest bladder point at rest, and the PCL to the lowest bladder point at evacuation significantly correlated with bladder descent. Receiver operating characteristic analysis was used to identify a measurement threshold to diagnose clinically significant cystocele for both measurements, bladder base to the H-line: -1.2 (80.0, 72.5) area under the curve (AUC) 0.82, and bladder base PCL: -3.3 (77.8, 79.5) AUC 0.86.

CONCLUSION

Our data support the application of using the minimal levator hiatus plane and specifically the H-line as a reliable landmark to diagnose bladder descent using MR defecography imaging.

Comparing Postoperative Pain With Laparoscopic Versus Robotic Sacrocolpopexy

STUDY OBJECTIVE

To compare postoperative pain and pain-related outcomes after laparoscopic (LS-MISC) vs robotic minimally invasive sacrocolpopexy (R-MISC).

DESIGN

A secondary analysis of an original placebo-controlled randomized controlled trial (RCT) examining preoperative intravenous (IV) acetaminophen on postoperative pain after MISC.

SETTING

Planned secondary analysis of multicenter RCT.

PATIENTS

Women undergoing MISC.

INTERVENTIONS

Coprimary outcomes at 24 hours were total opioid use in morphine milligram equivalents (MMEs) and visual analog scale (VAS) pain scores comparing LS-MISC and R-MISC. The secondary outcome was pain scores using a pain diary through 7 days after the procedure.

MEASUREMENTS AND MAIN RESULTS

The original study was a double-blind, multicenter, RCT comparing IV acetaminophen with placebo that took place between 2014 and 2017. Given that the original trial was unable to show an impact from the use of IV acetaminophen, our analysis focused on the impact of surgical modality. We included 90 subjects undergoing MISC: 65 LS-MISC and 25 R-MISC. Most were Caucasian (97.8%) and postmenopausal (88.9%) with mean age of 61.2 ± 7.2 years and body mass index of 27.6 ± 4.4 kg/m2. IV acetaminophen did not affect pain in the original study and was not different between LS-MISC and R-MISC. Concomitant hysterectomy was performed in 67% (LS-MISC) vs 60% (R-MISC, p = .49). LS-MISC underwent more perineorrhaphies (15.4% vs 0%, p = .04) and posterior repairs (18.5% vs 0%, p = .02). Operative time was longer with LS-MISC (208.5 ± 57.3 vs 143.6 ± 21.0 minutes, p <.01). Length of stay was longer with LS-MISC (0.9 ± 0.4 vs 0.7 ± 0.4 days, p = .02). Women undergoing LS-MISC consumed more opioid MMEs through 24 hours when including intraoperative opioids (48.5 ± 25.5 vs 35.1 ± 14.6 MME, p <.01). Using linear regression correcting for operative time and concomitant vaginal repairs, this difference disappeared. Likewise, when intraoperative opioids were excluded, there was no difference. There were no differences in 24-hour postoperative VAS scores, opioid use in the first week, or quality of life (Patient-Reported Outcomes Measurement Information System - Pain Interference Short Form, all p <.05).

CONCLUSION

When comparing VAS pain scores, MME opioid usage, and quality of life between LS-MISC and R-MISC, either there was no difference or differences disappeared after adjusting for confounders. Overall, opioid use, pain scores, and opioid side effects were low.

Pelvic Floor Disorders in Black Women: Prevalence, Clinical Care, and a Strategic Agenda to Prioritize Care

Pelvic floor disorders are a group of common conditions affecting women of all racial and ethnic groups. These disorders are undertreated in all women, but this is especially magnified in Black people who have been historically marginalized in the United States. This article seeks to highlight the prevalence of pelvic floor disorders in Black women, evaluate the clinical care they receive, examine barriers they face to equitable care, and present a strategic agenda to prioritize the care of Black women with pelvic floor disorders.

Robotic sacrocolpopexy

Pelvic organ prolapse (POP) is a common cause of gynecological disease in elderly women. The prevalence of POP has increased with an aging society. Abdominal sacrocolpopexy (ASC) is safer and more effective than the vaginal approach in patients with apical compartment POP because it has a higher anatomical cure rate, a lower recurrence rate, less dyspareunia, and improved sexual function. Laparoscopic sacrocolpopexy (LSC) has replaced ASC. Robotic sacrocolpopexy (RSC) also helps overcome the challenges of LSC by facilitating deep pelvic dissection and multiple intracorporeal suturing. The RSC is technically easy to apply, has a steep learning curve, and offers many advantages over the LSC. However, insufficient data led us to conclude that the LSC is superior overall, especially in terms of costeffectiveness. The present review provides insights into different aspects of RSC, highlighting the most common benefits and concerns of this procedure. We searched for eligible articles discussing this issue from January 2019 to March 2022 to reveal the outcomes of RSC.

Complete labia majora fusion after obliterative surgical procedure: a video case report

Obliterative surgical procedures have been classically used as a method to reduce pelvic organ prolapse in elderly women who do not wish to preserve the vagina for sexual intercourse. The aim of this video is to demonstrate a surgical technique of repairing complete labia majora fusion in a woman who had previously undergone one of these procedures. We present the case of an 80 year-old woman with a history of progressive difficulty on voiding onset and sensation of incomplete bladder emptying. She reported an obliterative procedure to correct her pelvic organ prolapse (POP) 10 years earlier. On physical examination, complete fusion of labia majora was observed, causing abnormal urinary drainage. Perineal reconstructive surgery was performed without complications and the application of topical Promestriene was prescribed. Optimal genital re-epithelization was observed during follow-up. As observed, patients undergoing obliterative surgery who present with genital atrophy are at increased risk of developing vulvar adherences. Applying vaginal moisturizers or local topical estrogens can prevent this condition. In severe vulvar fusions, early surgical treatment is recommended to prevent potentially serious complications.

Cross-Cultural Adaptation and Measurement Properties Analysis of the Brazilian Portuguese Version of the ICIQ-VS

INTRODUCTION AND HYPOTHESIS

The high prevalence of pelvic floor disorders in women requires assessments using validated instruments. We aimed to translate, cross-culturally adapt to Brazilian Portuguese, and analyze the measurement properties of the International Consultation on Incontinence Questionnaire Vaginal Symptoms Module (ICIQ-VS-Br).

METHODS

Participants were Brazilian women older than 18 years presenting vulvovaginal symptoms according to the Vulvovaginal Symptoms Questionnaire (VSQ-Br). The development of the ICIQ-VS-Br included the steps of translation, synthesis, back-translation, expert meeting, and pre-test. We analyzed construct validity by correlating the ICIQ-VS-Br and VSQ-Br. The participants answered the ICIQ-VS-Br the second time 7 to 10 days after the first response. We measured test-retest reliability using intraclass correlation coefficient (ICC), internal consistency using Cronbach's alpha, and construct validity using Pearson's correlation coefficient.

RESULTS

The study included 313 women. Reproducibility was analyzed for the three subscales of the ICIQ-VS-Br, resulting in an ICC of 0.92 (95% CI 0.89 to 0.94) for "vaginal symptoms," 0.85 (95% CI 0.78 to 0.89) for "sexual matters," and 0.87 (95% CI 0.81 to 0.91) for "quality of life." Construct validity showed a moderate correlation between ICIQ-VS-Br and VSQ-Br, confirming our hypotheses.

CONCLUSIONS

The ICIQ-VS-Br demonstrated validity and reproducibility, indicating that the instrument can be used in scientific research and clinical practice.

Quality-of-life improvements in patients after various surgical treatments for pelvic organ prolapse

OBJECTIVE

To compare the improvements in quality of life of patients with pelvic organ prolapse (POP) treated using various surgical methods.

MATERIALS AND METHODS

The PUBMED, MEDLINE and Cochrane Library online databases were searched using the keywords "pelvic organ prolapse", "surgery", "PFDI-20" and "PFIQ-7" for articles published from January 2010 to December 2022 that included quality-of-life scores before and after surgery.

RESULTS

Forty-nine articles were include. The mean postoperative PFDI-20 and PFIQ-7 scores decreased by 67.50% and 76.98%, respectively, compared with those before surgery. In 76.9% of patients, this change did not decrease with increased postoperative time. The improvement rate in PFDI-20 scores after colpocleisis did not differ statistically from that after sacrocolpopexy and was significantly higher than that after other procedures. The improvement rate in PFIQ-7 scores after colpocleisis did not statistically differ from that after high uterosacral ligament suspension and was significantly higher than that after other procedures. The improvement rate in PFDI-20 scores after transvaginal mesh-based repair (TVM) did not significantly differ from that after sacrospinous ligament fixation and was significantly lower than that after other procedures except traditional vaginal wall repair. The improvement rate in PFIQ-7 scores after TVM did not significantly differ from that after new procedures and was significantly lower than that after other procedures.

CONCLUSIONS

Surgical treatment can significantly improve the quality of life of patients with POP. Colpocleisis may offer more advantages than those of other surgical procedures, and improvement was lower after TVM than after other procedures.

Impact of Mannitol Bladder Distension in the Intraoperative Detection of Ureteral Kinking During Pelvic Floor Surgery

INTRODUCTION AND HYPOTHESIS

Ureteral injuries are the most feared complications of gynecological surgery and therefore intraoperative recognition is of the utmost importance. Intraoperative cystoscopy represents the diagnostics of choice to investigate ureteral patency thanks to the direct visualization of ureteral flows after administration of infusion mediums. In this study, we aimed to compare the diagnostic performance of saline versus mannitol intraoperative cystoscopy in terms of false negatives in a large cohort of patients.

METHODS

We retrospectively analyzed data of patients who underwent vaginal hysterectomy and high uterosacral ligament suspension for POP. Patients were divided in two groups based on the use of saline or mannitol medium for intraoperative cystoscopy. Postoperative daily control of serum creatinine was performed until discharge, as well as urinary tract imaging, in symptomatic patients.

RESULTS

A total of 925 patients underwent vaginal hysterectomy followed by high USL suspension for POP. Saline and mannitol medium were used in 545 patients and 380 patients respectively. Postoperative ureteral injuries were identified in 12 patients, specifically in 2% of the saline group and in 0.3% of the mannitol group.

CONCLUSIONS

The use of mannitol instead of saline as a bladder distension medium was able to significantly reduce the occurrence of postoperative ureteral sequelae.

The Incidence of Pelvic and Low Back Pain in Patients with Pelvic Organ Prolapse

INTRODUCTION AND HYPOTHESIS

To define the prevalence and incidence of pelvic/low back pain in patients with pelvic organ prolapse (POP).

METHODS

Patients presenting for POP to three urogynecology centers in the US, UK, and Chile were enrolled in an IRB-approved cross-sectional study assessing pain, GU, GI and sexual function symptoms. For prevalence, symptoms were noted as present if the participant recorded the symptom and reported the degree of bother as "somewhat," "a moderate amount," or "a lot." For incidence, participants were queried if the symptom's onset concurred with the POP. We also queried if they perceived the symptom was worsened by their POP.

RESULTS

Two hundred five participants were recruited: 100 from the US, 46 from the UK, and 59 from Chile. One US participant was excluded due a missing examination. The prevalence of pelvic pain was 42%. Seventy-three percent of these participants reported the onset of pelvic pain coinciding with prolapse onset, and 81% endorsed worsening pelvic pain with POP. The prevalence of low back pain was 46%, with 30% reporting the onset coincided with the onset of POP and 44% responded that prolapse worsened their pain.

CONCLUSION

A higher proportion of participants than expected endorsed pelvic/low back pain. Among patients with pelvic pain, the majority experienced symptom onset with POP onset and a worsening of pain with POP. While roughly half of participants reported low back pain; a minority correlated this to their POP. These findings highlight a high incidence of pelvic pain, challenging the perception of POP as a painless condition.

Healthcare Resource Utilization Following Minimally Invasive Sacrocolpopexy: Impact of Concomitant Rectopexy

INTRODUCTION AND HYPOTHESIS

Combined surgical procedures with sacrocolpopexy (SCP) and rectopexy (RP) are more commonly being performed for treatment of multicompartment pelvic organ prolapse. This study aimed to compare healthcare resource utilization (HRU) within 6 weeks following combined surgery (SCP-RP) versus SCP alone (SCP-only). We hypothesized that concomitant RP does not impact HRU.

METHODS

A retrospective cohort study of patients who underwent minimally invasive SCP from 2017 to 2022 was conducted at a tertiary referral center. Patients were grouped based on the performance of concomitant RP. HRU was defined as a composite of unscheduled office visits, emergency department visits, and readmissions before the 6-week postoperative visit. HRU was compared in the SCP-RP and SCP-only groups. Multivariable regression analysis was performed to identify factors associated with HRU.

RESULTS

There were 144 patients in the SCP-RP group and 405 patients in the SCP-only group. Patient characteristics were similar between the two groups, with the following exceptions: the SCP-RP group was older, more likely to have comorbid conditions, and live >60 miles from the hospital. Of the 549 patients, 183 (33.3%) had ≥1 HRU encounter within 6 weeks after surgery. However, there was no difference between the SCP-RP and SCP-only groups in composite HRU (34.0% vs 33.1%, p = 0.84). The most common reasons for HRU were pain, urinary tract infection symptoms, and wound issues. Concomitant mid-urethral sling was associated with a two-fold increased risk of HRU after surgery.

CONCLUSIONS

One in 3 patients undergoing minimally invasive SCP had at least one unanticipated encounter within 6 weeks after surgery. Concomitant RP was not associated with increased postoperative HRU.

The unmet needs in vaginal pessaries

A pessary is a medical device that is inserted into the vagina to provide structural support to one or more of the descending vaginal compartments in women with pelvic organ prolapse. It is a common management option offered to women in the short and long term. This article will discuss the current use of vaginal pessaries for POP, the current challenges with their use and common complications seen in practise. It will also discuss the unmet needs in the current products available on the market and suggest ideas for product design, materials and considerations for future development.

["Do uro-gynecology multidisciplinary team meeting modify therapeutic management?"]

INTRODUCTION

Since the banning of trans-vaginal meshes for pelvic organ prolapse treatment by the FDA in 2019, French authorities have been gradually regulating the use of prosthetic materials in urogynecology. The decision to fit a mid-urethral sling or a reinforcement implant for the cure of prolapse, as well as the management of complex genital prolapse and serious post-implant complications, must be the subject of multidisciplinary consultation and a shared medical decision. To comply with these regulations, multidisciplinary team meetings (MDTMs) have been set up. The aim of the study was to evaluate the impact of these meetings on patient management.

MATERIAL

We carried out a retrospective study in a tertiary hospital in France on all cases presented in MDTM of urogynecology over the year 2022. MDTMs were held weekly, with a "Prosthesis MDTM" focusing on slings, sacrocolpo/hysteropexies and prosthetic complications, lead by the urology team, and a "Prolapse MDTM" focusing on pelvic organ prolapse and complex prolapses, lead by the gynecology team. We compared the initial proposal of the patient's referring physician versus the final proposal of the MDTM.

RESULTS

Three hundred and seventy-five cases were presented in our center in 2022: 188 in Prosthetic MDTM and 187 in Prolapse MDTM. The Prosthetic and Static MDTMs agreed with the initial proposal in 83 and 64% of cases respectively, while the therapeutic strategy was questioned in 12 and 36% of cases respectively.

CONCLUSION

For almost a quarter (24%) of patients, the MDTM of urogynecology opted for a different management from that proposed by the referring physician. The presentation of cases to the MDTM is a legal obligation in specific indications. It also plays an educational role, enabling shared decision-making and responsibility, which is an asset in functional surgery.

LEVEL OF EVIDENCE: 4

Minimally Invasive Sacrohysteropexy Versus Vaginal Hysterectomy with Uterosacral Ligament Suspension for Pelvic Organ Prolapse: a Prospective Randomized Non-Inferiority Trial

STUDY OBJECTIVE

To investigate whether minimally invasive Sacrohysteropexy (SH) is non-inferior to vaginal hysterectomy (VH) with uterosacral ligament suspension (USLS) in women with symptomatic uterovaginal prolapse.

DESIGN

Prospective, randomized, non-inferiority study.

SETTING

Tertiary university-based hospital.

PATIENTS

A total of 146 patients with uterovaginal prolapse between July 2016 and August 2019.

INTERVENTIONS

Patients were randomly assigned in a 1:1 ratio to either laparoscopic or robotic SH surgery or VH with USLS surgery.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was prolapse recurrence at 1 year after surgery, defined as prolapse ≥ stage 2 evaluated using the pelvic organ prolapse quantification system, bothersome vaginal bulge symptoms, or retreatment for prolapse. The secondary outcomes included operation time, estimated blood loss, hospital stay, operation-related complications, pain intensity, quality of life, and activities of daily living. Of 146 women who underwent randomization, 73 in the SH group and 73 in the VH with USLS group were analyzed. SH was non-inferior for recurrence compared with VH with USLS (16.4% vs 15.8%, 95% confidence interval: -13.0% to 14.2%). Operating duration and transvaginal length were significantly longer in the SH group, while there were no significant differences in the estimated blood loss, length of hospital stay, or postoperative complication rates. Although perioperative pain intensity was greater from 1 week to 1 month in the SH group, the quality of life and activities of daily living did not differ between the groups throughout postoperative year 1.

CONCLUSION

Laparoscopic or robotic SH was non-inferior to VH with USLS for the recurrence of pelvic organ prolapse at the 1-year follow-up.

Accelerometer-measured physical activity, sedentary behavior, and risk of incident pelvic organ prolapse: a prospective cohort study in the UK Biobank

BACKGROUND

Previous studies on physical activity (PA) and pelvic organ prolapse (POP) were largely limited to self-reported PA in athletes, soldiers, and women in postpartum. We aimed to investigate the association of accelerometer-measured PA and sedentary behavior with the risk of POP in middle-aged and elderly women.

METHODS

In this prospective cohort derived from the UK Biobank, the intensity and duration of PA and sedentary behavior were measured with wrist-worn accelerometers over a 7-day period in 2013-2015 for 47,674 participants (aged 42.8-77.9 years) without pre-existing POP. Participants were followed up until the end of 2022, during which incident POP was ascertained mainly by the electronic health records. Multivariable-adjusted Cox proportional hazards models and restricted cubic splines were used to assess the associations of interest. Isotemporal substitution models were applied to test the effects of substituting a type of activity with equivalent duration of others.

RESULTS

During a median follow-up of 8.0 years, 779 cases of POP were recorded. The duration of light-intensity PA (LPA) was positively whereas sedentary time was negatively associated with the risk of POP. Every additional 1 h/day of LPA elevated the risk of POP by 18% (95% confidence interval [CI], 10%-26%). In contrast, the risk decreased by 5% (95% CI, 0-8%) per 1 h/day increment in sedentary behavior. No associations were found between moderate-intensity PA (MPA) or vigorous-intensity PA (VPA) and POP, except that women who had a history of hysterectomy were more likely to develop POP when performing more VPA (53% higher risk for every additional 15 min/day). Substituting 1 h/day of LPA with equivalent sedentary time was associated with a 18% (95% CI, 11%-24%) lower risk of POP. The risk can also be reduced by 17% (95% CI, 7%-25%) through substituting 30 min/day of LPA with MPA.

CONCLUSIONS

More time spent in LPA or less sedentary time was linked to an elevated risk of POP in middle-aged and elderly women, while MPA or VPA was not. Substituting LPA with equivalent duration of sedentary behavior or MPA may lower the risk of POP.

Vaginal microflora following the use of a disposable home-use vaginal device and a commercially available ring pessary for pelvic organ prolapse management: a randomized controlled trial

PURPOSE

To investigate whether ProVate, a novel, disposable, self-inserted vaginal device for pelvic organ prolapse management, clinically affects the vaginal microflora, as compared with a commercially available ring pessary, to assess its microbiological safety.

METHODS

This interventional, prospective, multi-center, open-label, randomized, controlled, statistically powered (noninferiority), home-use, crossover study was conducted at seven sites. Participants were randomized into either group A (using ProVate and then a new reusable commercially available ring pessary [control]) or B (using control device and then ProVate) with a 1:1 ratio. Noninferiority of ProVate over the control was evaluated for the primary endpoint, which was based on meeting one of the failure criteria: significant change in Lactobacillus spp., Gardnerella vaginalis, Candida morphotypes, or Staphylococcus aureus levels compared to the baseline (significant change: Nugent score ≥ 7 or > 1 scale unit increase in S. aureus or Candida morphotype), bothersome vaginal infection symptoms, or symptoms requiring treatment for infection.

RESULTS

The study included 58 participants (mean age: 64.5 years, 91.4% postmenopausal). There were no significant microfloral changes in terms of the four microorganisms mentioned above, the rate of Nugent score ≥ 7 after use was low and comparable between the two devices, and the rate of patients with a > 1 unit-scale change (increase or decrease) from the baseline to the end-of-use phase in any studied microorganism was comparable between the devices. The failure rate was 15.5% for ProVate and 15.5% for control while using 383 ProVate devices over 1647 days or one control device throughout the study. Two patients had bothersome vaginal complaints and one had overt vaginal infection in the control group, but no such cases were observed in the ProVate group.

CONCLUSION

The primary endpoint of possible vaginal microbial changes, bothersome vaginal symptoms, or treatment-requiring vaginal complaints while using ProVate was successfully met. Our findings show that the vaginal microflora is comparable when using either ProVate or commercially available ring pessary (control) with a relatively low rate of vaginal infections.

Early growth response 2, a novel target of pelvic organ prolapse, is highly expressed in anterior vaginal wall tissues with pelvic organ prolapse

Pelvic organ prolapse (POP) is a common disorder among women that negatively affects women's quality of life. Early growth response 2 (EGR2) is a transcription factor that regulates cell growth. The present study aimed to explore the role of EGR2 in POP progression and provided a new target for the treatment and prevention of POP. Firstly, we extracted primary vaginal anterior wall fibroblasts from POP tissues and non-POP tissues and then constructed an EGR2-silencing lentivirus for further study. Immunoblotting, qPCR, TUNEL assay, CCK-8 assay, dual luciferase assay, and ELISA assay were carried out. EGR2 expression was much higher in POP tissues than in control tissues, and EGR2 expression positively correlated with cytokine signaling 3 (SOCS3) expression. Knockdown of EGR2 increased cell proliferation, upregulated PCNA expression, and reduced apoptosis in POP fibroblasts. Moreover, we found that the knockdown of EGR2 increased COL1A1, COL3A1, and Elastin expression and decreased MMP2 and MMP9 activities, and knockdown of EGR2 increased TGF-β/Smad pathway activity in POP fibroblasts. Interestingly, the results of dual luciferase assay demonstrated that EGR2 was able to increase SOCS3 transcriptional activity. EGR2 knockdown alleviated the apoptosis of POP fibroblasts by reducing SOCS3 expression and improving the proliferation and collagen synthesis of POP fibroblasts. Overall, our study illustrated that EGR2 was highly expressed in POP tissues, and knockdown of EGR2 alleviated apoptosis and reduced matrix degradation in POP fibroblasts. This study might provide a new insight into the pathogenesis of POP.

Prevention of complications of surgical treatment of stage III-IV cystocele using light polypropylene mesh

OBJECTIVE

The purpose of study was to report the subjective and objective results of different methods of surgical treatment of cystocele using the transvaginal Mesh-system.

METHODOLOGY

A prospective study was conducted from January 2017 to December 2020 comparing anterior colporrhaphy with vaginal mesh and two distinct types of vaginal wall repair sutures in the surgical treatment of cystocele. The primary endpoint was the incidence rate of vaginal wall erosion complications 12 months after surgery. Secondary endpoints were anatomic outcomes, TVM-related morbidity, and patient satisfaction measured using validated questionnaires.

RESULTS

In total, 102 patients with stage III-IV cystocele and the average age of 67.2 ± 3.1 years (age range of 47-79 years old) took part in the study. Of the 102 women initially enrolled, 102 (100%) were successfully followed up 12 months after primary surgery. The primary result, the objective erosion development, was radically different in the comparison groups (1.6% against 23.5%, respectively). Analysis of the improved method of operative treatment showed a prominent level of positive, uncomplicated, surgery results of 98.4% (60/61). The anatomic success rate of recovery from cystocele was 99.9% (101/102) 12 months after surgery.

CONCLUSION

The suggested method of restoring the anterior vaginal wall in stage III-IV isolated cystocele without signs of incomplete and complete prolapse of the uterus showed a radically positive result. The number of complications was relatively high in the comparison group, but no difference was observed in satisfaction with the anatomical results of the surgery. The percentage of the vaginal wall erosion when using a single-layer suture is 23.5%, when using a two-layer suture is 1.6.

Pessaries for pelvic organ prolapse: evaluation of vaginal discharge and pain during pessary cleaning in an outpatient setting

INTRODUCTION AND HYPOTHESIS

Pessary treatment for pelvic organ prolapse (POP) is effective and safe, but long-term continuation is low. Pain and vaginal discharge may play a role. This study was aimed at evaluating vaginal discharge and pain during pessary cleaning in an outpatient setting and in continuous pessary use.

METHODS

Women with POP who attended the outpatient clinic for pessary cleaning between January and October 2021 were included. Primary outcome was pain during removal and reinsertion of the pessary, measured by an 11-point numeric rating scale (NRS). Secondary outcome was vaginal discharge, measured by the NRS and Patient Global Impression of Change scale (PGI-C). Multiple linear regression analysis was used to identify associated variables for pain and discharge.

RESULTS

A total of 150 women were included. Mean NRS during pessary removal was 4.3 (± 2.7), with 25% of women scoring a 7 or higher. Mean NRS during reinsertion was 1.8 (± 2.0). A smaller genital hiatus and presence of vaginal atrophy or vulvar skin disease were associated with pain during pessary removal. Mean NRS for vaginal discharge was 2.5 (± 2.3). Twenty-five percent of women reported that their vaginal discharge was "(very) much worse" than before they used a pessary. Presence of vaginal erosions was associated with vaginal discharge in this study population.

CONCLUSIONS

Removing a pessary in an outpatient setting is a painful procedure for many women who use a pessary continuously. Moreover, 25% of these women experience an increase in vaginal discharge while using a pessary. Future research should focus on reducing these disadvantages.

Voiding Dysfunction in Patients With Advanced Pelvic Organ Prolapse and Bladder Outlet Obstruction Following Pelvic Reconstructive Surgery: Urodynamic Profile and Predictive Risk Factors

STUDY OBJECTIVE

To determine the outcome of voiding function 1 year after pelvic reconstructive surgery (PRS) in women with bladder outlet obstruction (BOO).

DESIGN

Retrospective cohort study.

SETTING

Tertiary referral hospital.

PATIENTS

A total of 1894 women underwent PRS for advanced pelvic organ prolapse (POP) stages 3 to 4 with urodynamic findings of BOO.

INTERVENTIONS

PRS.

MEASUREMENTS

The primary outcome measured was the resumption of normal voiding function, defined clinically with multichannel urodynamic testing at 1 year postoperatively. The secondary outcomes were to identify the different risk factors for persistence voiding dysfunction (VD) 1 year after PRS.

MAIN RESULTS

A total of 431 women with Pelvic Organ Prolapse Quantification stages 3 and 4, urodynamic study of maximum urinary flow rate ≤15 mL/s, and detrusor pressure at maximum flow ≥20 cm H2O were included. Resumption of normal voiding function was found in 91% (n = 392 of 431), whereas 9% (n = 39 of 431) remained to have VD 1 year postoperatively. Those with persistent VD, 20.5% (n = 8 of 39) remained having urodynamic diagnosis of BOO. Univariate and multivariate logistic regression revealed factors associated with postoperative VD were pre-operative maximal cystometric capacity ≥500 mL and postvoid residual volume ≥200 mL.

CONCLUSION

VD may persist in women with BOO after PRS, particularly in those with preoperative maximal cystometric capacity of >500 mL and postvoid residual volume >200 mL.

Molecular mechanisms of pelvic organ prolapse influenced by FBLN5 via FOSL1/miR-222/MEIS1/COL3A1 axis

This study delves into the role of FBLN5 in pelvic organ prolapse (POP) and its molecular mechanisms, focusing on the FOSL1/miR-222/MEIS1/COL3A1 axis. Gene relationships linked to POP were confirmed using bioinformatics databases like GEO and StarBase. Primary human uterosacral ligament fibroblasts (hUSLF) were extracted and subjected to mechanical stretching. Cellular cytoskeletal changes were examined via phalloidin staining, intracellular ROS levels with a ROS kit, cell apoptosis through flow cytometry, and cell senescence using β-galactosidase staining. FBLN5's downstream targets were identified, and the interaction between FOSL1 and miR-222 and miR-222 and MEIS1 were validated using assays. In rat models, the role of FBLN5 in POP was assessed using bladder pressure tests. Results indicated diminished FBLN5 expression in uterine prolapse. Enhanced FBLN5 countered mechanical damage in hUSLF cells by downregulating FOSL1. FOSL1 augmented miR-222, inhibiting MEIS1, which subsequently fostered COL3A1 transcription. In rat models, the absence of FBLN5 exacerbated POP by influencing the FOSL1/miR-222/MEIS1/COL3A1 pathway. FBLN5's protective role likely involves regulating the above axis and boosting COL3A1 expression. Further research is needed to validate the effectiveness and safety of this mechanism in human patients and to propose potential new treatment options.

Projecting future prolapse outcomes with induction of labor at 39 weeks: a decision analysis

INTRODUCTION AND HYPOTHESIS

In 2018, the ARRIVE trial (A Randomized Trial of Induction Versus Expectant Management) concluded that routine induction of labor (IOL) at 39 weeks gestation decreases cesarean delivery risk, with slightly lighter birthweight infants. We debated whether routine IOL would improve, worsen, or not change POP risk compared with expectant management (EM).

METHODS

We constructed a decision analysis model with a lifetime horizon where nulliparous women reaching 39 weeks underwent IOL or EM. Subsequent vaginal versus cesarean delivery varied based on prior deliveries for up to four births. Subsequent delivery prior to 39 weeks and distribution of gestational age, birthweight, and delivery mode between 24 and 39 weeks was modeled from national data. We modeled increased POP risk with increasing vaginal parity, forceps delivery, and weight of largest infant delivered vaginally, accounting for differential infant weights in each strategy.

RESULTS

IOL and EM have similar population-wide POP risk (15.9% and 15.7% respectively). Among women with only spontaneous vaginal deliveries that reached 39 weeks or beyond, the prevalence of POP was 20% after one delivery and 29% after four deliveries, with no difference between groups. The cesarean rate was lower with IOL (27.8% versus 29.8%). Sensitivity analysis revealed no meaningful thresholds among the variables, supporting model robustness.

CONCLUSION

While routine induction of labor at 39 weeks results in a meaningfully higher vaginal delivery rate, there was no increase in POP, possibly due to the protective effect of lower birthweight.

Transvaginal extraperitoneal single-port laparoscopic sacrocolpopexy for apical prolapse after total/subtotal hysterectomy: Chinese surgeons' initial experience

BACKGROUND

To introduce a novel technique of transvaginal extraperitoneal single-port laparoscopic sacrocolpopexy (ESLS) for apical prolapse and to evaluate the feasibility and short-term outcomes of this technique.

METHODS

Sixteen patients were enrolled to undergo ESLS between January 2020 and May 2021. Perioperative outcomes were included. Short-term results were assessed by Pelvic Floor Distress Inventory-20 (PFDI-20), Pelvic Organ Prolapse Quantification (POP-Q) scores, mesh exposure and prolapse recurrence.

RESULTS

A total of 14/16 cases (87.5%) were successfully completed. The mean operation time was 118 min (range 85-160), and the mean blood loss was 68 ml (range 20-100). The mean postoperative visual analog scale (VAS) pain score at 24 h was 0.7. No intraoperative complications occurred except for one patient who developed subcutaneous emphysema. All patients gained a significant improvement in both physical prolapse and quality of life at 12 months after surgery, and there was no mesh exposure or prolapse recurrence.

CONCLUSIONS

Our experience showed that transvaginal ESLS is a feasible and effective technique for apical prolapse with a previous hysterectomy. However, this technique should be performed by surgeons with extensive experience both in vaginal surgery and laparoscopic single-port surgery.

Transvaginal natural Orifical transluminal Endoscopy for sacrocolpopexy: A case series report

Background

To describe the surgical technique and operative outcomes of transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) for sacrocolpopexy with or without robotic surgical system in patients with pelvic organ prolapse (POP).

Methods

Patients with POP undergoing traditional transvaginal natural orifice transluminal endoscopic surgery (TV-NOTES) or robotic transvaginal natural orifice transluminal endoscopic surgery (RV-NOTES) for sacrocolpopexy performed by one surgeon from Sep 2020 to Jan 2023 in our hospital were included in this study. The baseline demographics and operative outcomes were collected and analyzed. In addition, some surgical skills were presented. The operative outcomes of V-NOTES for sacrocolpopexy performed by three beginners were also presented.

Results

Eight patients who underwent TV-NOTES, and two patients who underwent RV-NOTES were included in this study. The mean operative time was 180 ± 49 min, and the estimated blood loss was 107 ± 82 ml for these ten cases. Particularly, the operative time of the two patients who underwent RV-NOTES was 275 and 132 min, while the estimated blood loss (EBL) was 100 and 50 ml respectively. During the follow-up period, no mesh exposure and recurrence were observed. In addition, five cases of TV-NOTES for sacrocolpopexy by beginners were all successfully completed.

Conclusion

Both TV-NOTES and RV-NOTES appeared to be feasible and safe for sacrocolpopexy.

Impact of childbirth on pelvic floor dysfunction in women who have undergone previous pelvic floor reconstructive surgery: systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

The aim of the study was to perform a systematic review and meta-analysis of the impact of pregnancy and childbirth (vaginal delivery [VD]) or cesarean section (CS) on the recurrence of pelvic floor disorders in women who had previously undergone pelvic floor reconstructive surgery for pelvic organ prolapse (POP) or stress urinary incontinence (SUI), to facilitate future evidence-based counseling.

METHODS

PubMed, Cochrane, Embase, BJOG, Scopus, etc. were screened, from 1990 to date. Inclusion criteria included cohort studies, case-control studies, case series, and case reports that reported on the primary outcome measure of the review. Exclusion criteria included studies on surgical procedures whose outcomes are unlikely to be impacted by pregnancy and childbirth or are obsolete. Meta-analysis was performed using Review Manager 5.3.

RESULTS

Seven papers on midurethral slings (MUS; 181 women in both VD and CS groups respectively) and three papers on different hysteropexy techniques (47 and 29 women in the VD and CS groups respectively), were included in the meta-analysis. No difference was seen between the two groups regarding the recurrence of SUI in women who had previously undergone MUS surgery (OR: 1.18 [0.66, 2.09]; Z = 0.56; p = 0.58) or the recurrence of POP following hysteropexy using various apical suspension procedures (OR: 1.81 [0.04, 80.65]; Z = 0.31; p = 0.76). There are insufficient data to support meta-analyses for individual MUS sub-types or hysteropexy procedures.

CONCLUSION

Current literature does not demonstrate a protective effect of CS in preventing recurrent SUI in women who had undergone MUS surgery for SUI. When hysteropexy is considered irrespective of the apical suspension procedure employed, the incidence of recurrent POP appears similar after CS and VD.

Pelvic floor symptoms among premenopausal women with pelvic organ prolapse in the Democratic Republic of the Congo

INTRODUCTION AND HYPOTHESIS

Most of the literature on pelvic organ prolapse (POP) has been generated from postmenopausal patients in high-income countries. In the Democratic Republic of the Congo (DRC), a significant proportion of patients who present for surgical management of POP are premenopausal. Little is known about the impact of POP on pelvic floor symptoms in this population. The objective was to describe pelvic floor symptoms and sexual function among premenopausal patients presenting for POP surgery in DRC.

METHODS

We performed a prospective cohort study of symptomatic premenopausal patients undergoing fertility-sparing POP surgery at a large referral hospital in the DRC. Pelvic floor symptoms were evaluated with the Pelvic Floor Distress Inventory Questionnaire and sexual function with the Pelvic organ prolapse/urinary Incontinence Sexual Questionnaire. Data are presented as means with standard deviations or counts with percentages.

RESULTS

A total of 107 patients were recruited between April 2019 and December 2021. All had either stage III (95.3%) or stage IV (4.7%) prolapse. Ages were 34.2 ± 6.7 years; 78.5% were married. A majority of patients experienced low abdominal pain (82.2%), heaviness or dullness (95.3%), and bulging or protrusion of the prolapse (92.5%). Almost two-thirds of patients reported no longer being sexually active, and 80% stated that they were not sexually active because of POP. Of the 37 sexually active patients (34.6%), nearly all reported significant sexual impairment because of the prolapse, with only 4 reporting no sexual impairment.

CONCLUSIONS

This study represents one of the largest prospective series of patients with premenopausal POP. Our results highlight the severity of pelvic floor symptoms and the negative effects on sexual function among this patient population with POP.

Does variation of surgical technique affect native tissue anterior pelvic organ prolapse repair outcomes?

INTRODUCTION AND HYPOTHESIS

The Variation in Surgical Technique study (VaST), demonstrated the large variation in surgical techniques used in native tissue (NT) anterior pelvic organ prolapse (POP) repairs. However, there are few comparative studies of different surgical techniques. This study was aimed at exploring whether surgical technique influenced the outcomes of NT anterior POP repairs.

METHODS

The surgical techniques of 22 consultant surgeons performing NT anterior POP repairs were filmed and categorised. These surgeons performed 809 anterior repairs within the PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trial (PROSPECT). Logistical regression models were used to determine the influence of the different surgical techniques on subjective and objective outcomes, using data collected during PROSPECT.

RESULTS

In adjusted multivariate linear regression models, fascial-flap repair was associated with an improved subjective outcome (POP-SS) compared with midline plication (β = -2.50 [-4.42 to -0.57]; p = 0.01). At 12 months, separate fascial defect repair was associated with a poorer objective outcome than midline plication (OR 6.06 [1.82-3.52], p = 0.006). At 24 months, deep dissection was associated with a poorer POP-SS than superficial dissection (0.32-2.60, p = 0.0). Continuous-locking closure of the skin was also associated with improved POP-SS compared with continuous non-locking closure (12 months: β = -1.94 [-3.42 to -0.45], p = 0.01).

CONCLUSION

Surgical technique may influence the outcome of native tissue anterior POP repairs. Our results should not change practice but inform future research; to develop methods of explicitly recording surgical techniques and allow confirmation of the effect of these aspects of technique on outcome.

Iliac vein variation in the sacral promontory on three-dimensional computed tomography angiography: a prospective observational study before laparoscopic sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

Venous injury may occur during exposure of the anterior longitudinal ligament at the anterior sacral promontory (SP). We aimed to quantitatively measure the extent of the vascular window (VW) in front of the SP in patients with internal iliac vein (IIV) variations using preoperative three-dimensional computed tomography angiography (3DCTA). We hypothesized that patients with IIV variations would have a narrow VW.

METHODS

This prospective observational study included patients scheduled for laparoscopic sacrocolpopexy (LSC) between July 2022 and April 2023 who underwent preoperative 3DCTA. The primary endpoint was the VW measurement in the standard and variant IIV groups using 3DCTA before LSC. The secondary endpoint was the difference between the two IIV groups adjusted for age, body mass index, hypertension, and diabetes using an analysis of covariance (ANCOVA) model. Multiple regression analysis was performed to analyze the effect of factors on the distance from the SP to great vascular bifurcations.

RESULTS

There were 20 cases of IIV variation (20.2%). VW was 28.8 ± 12.4 mm in the variant group and 39.6 ± 12.6 mm in the standard group (p = 0.001). In the ANCOVA model, IIV variations affected VW (coefficient, -11.8; 95% confidence interval [CI], -18.4 to -5.08, p < 0.001). Multivariate analysis revealed that the aorta-SP distance decreased with age (coefficient, -0.44; 95% CI, -0.77 to -0.11, p = 0.009).

CONCLUSIONS

One in five women has a vascular variant at the SP that restricts the "safe" zone of fixation to < 3 cm.

Impact of preoperative pelvic floor muscle function on the success of surgical treatment of pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

The objective of this study was to identify the potential characteristics of pelvic floor muscles (PFM) in the preoperative assessment that could be associated with post-surgical prolapse severity. We hypothesized that the same variables, if identified, could be addressed in preoperative rehabilitation to improve surgical results.

METHODS

This was a single-center prospective observational study that included women who underwent surgical pelvic organ prolapse repair between 2020-2022. Genital prolapse was evaluated according to the Pelvic Organ Prolapse Quantification (POP-Q) system. All the participants underwent a PFM assessment, including a vaginal digital assessment and manometry (Peritron™ 9300 V) before surgery and at 1-, 3-, and 6-month follow-ups. Several PFM variables were recorded: vaginal resting pressure, vaginal pressure during maximal voluntary contraction (MVC), area under the curve during a 10-second MVC, ability to correctly contract the PFMs, and reflexive activation during cough and relaxation. The primary endpoint of the analysis was objective surgical success defined as POP-Q 0 or 1 at the 6-month follow-up. Additionally, a change in pelvic floor muscle function was recorded during postoperative visits.

RESULTS

A total of 106 females were included in the study. Fifty-one were lost during the 6-month follow-up, which is a major limitation of the study. None of the examined parameters evaluating PFM were associated with surgical success. No statistically significant difference was found in MVC and PFM endurance before and after surgery. Post-surgery, a significant change was observed in the vaginal resting pressure and the ability to correct PFM activation and relaxation.

CONCLUSIONS

Preoperative PFM function is not associated with surgical success 6 months after surgery.
