Risk factors for pelvic organ prolapse recurrence after sacrospinous hysteropexy or vaginal hysterectomy with uterosacral ligament suspension

The Role of Uterine Preservation at the Time of Pelvic Organ Prolapse Surgery

OBJECTIVE

The aim of the study was to synthesize the current literature and provide surgeons with data to inform counseling of eligible patients for uterine-preserving prolapse surgery (UPPS).

METHODS

We compared UPPS to similar techniques incorporating hysterectomy, including native-tissue repairs by vaginal, laparoscopic, or open approach; mesh-reinforced repairs by vaginal, laparoscopic, or open approach; obliterative repairs; and the Manchester procedure. Reviewed outcomes include surgical and patient-reported outcomes, complications, uterine pathology, and sexual function. We conducted a structured literature search of English language articles published 1990-2023, combining MeSH terms for pelvic organ prolapse and UPPS. Data were categorized by procedure and approach, and evaluated to provide recommendations and strength of evidence based on group consensus.

RESULTS

Patient counseling on prolapse surgery should follow a benefit/risk assessment related to techniques that preserve the uterus. The discussion should include the benefits of hysterectomy for cancer detection and prevention and acknowledgment that patients should continue cervical cancer screening and evaluation of abnormal uterine bleeding following UPPS. The rate of hysterectomy after UPPS is low and most commonly for recurrent prolapse. If cervical elongation is present, trachelectomy should be considered at the time of UPPS. There is no difference in sexual function between UPPS and prolapse repair with hysterectomy. Data on pregnancy outcomes following UPPS are limited.

CONCLUSIONS

Uterine-preserving prolapse surgery should be a surgical option for all patients considering surgical treatment for symptomatic pelvic organ prolapse unless contraindications exist. Uterine-preserving prolapse surgery should be offered using an individualized benefit and risk discussion of both approaches to help patients make an informed decision based on their own values.

Postoperative Activity Restrictions After Reconstructive Pelvic Surgery

IMPORTANCE

Restrictive physical activity after pelvic reconstructive surgery is recommended, although the optimal duration and intensity are not standardized.

OBJECTIVE

This systematic review and meta-analysis aimed to evaluate the existing literature comparing clinical outcomes for liberal postoperative physical activity versus standard of care, defined as restricted postoperative physical activity, after pelvic reconstructive surgery.

STUDY DESIGN

PubMed, CENTRAL, Scopus, Web of Science, and CINAHL databases were searched for observational and randomized studies comparing liberal postoperative physical activity and standard of care in women undergoing pelvic reconstructive surgery, reporting anatomic and functional outcomes. Statistical analysis was performed using RevMan software, presenting results as mean difference (MD) or odds ratio in a random-effects model, with 95% confidence intervals (CIs).

RESULTS

Five randomized trials, representing total n = 434, were included, with 2 studies on sling surgical procedures and 3 on prolapse surgical procedures. Data from 3 studies suggest no significant difference between liberal and standard postoperative instructions in surgical outcomes, measured by Point Ba from POP-Q assessment tool, up to 3 months follow-up (MD, -0.04; 95% CI, -0.16 to 0.07; P = 0.49). Disease-specific symptom distress, measured by Pelvic Floor Distress Inventory-20, favored the liberal approach (MD, -10.09; 95% CI, -18.33 to -1.86; P = 0.02). Other domains, including Urinary Distress Inventory-6, also showed significant improvements with liberal postoperative activities (MD, -4.29; 95% CI, -7.84 to -0.74; P = 0.02).

CONCLUSIONS

Patients with liberal postoperative physical activity recommendations in prolapse repair surgical procedures had similar short-term anatomic outcomes compared with standard restrictions, with more favorable outcomes in disease-specific symptom relief and quality of life.

The External Validation of a Multivariable Prediction Model for Recurrent Pelvic Organ Prolapse After Native Tissue Repair: A Prospective Cohort Study

Background/Objectives: A prediction model for anatomical cystocele recurrence after native tissue repair was developed and internally validated in 2016. This model estimates a patients' individual risk of recurrence and can be used for counseling. Before implementation in urogynecological clinical practice, external validation is needed. The aim of this study was to assess the external validity of this previously developed prediction model. The secondary aim was to test the performance of this model with a composite and subjective outcome of pelvic organ prolapse (POP) recurrence. Furthermore, the aim was to investigate whether risk factors for POP recurrence were in line with the population in which the original model was developed. Methods: In this prospective multicenter cohort study, 246 patients who underwent anterior colporrhaphy were included. Inclusion criteria were patients scheduled to undergo a primary anterior colporrhaphy (with a POP Quantification (POPQ) stage ≥ 2 cystocele). A combination of a primary anterior colporrhaphy with other POP or incontinence surgery (without the use of vaginal or abdominal mesh material) was permitted. Patients with prolapse or incontinence surgery prior to index surgery could not participate. All patients filled in questionnaires, pelvic floor ultrasound was performed preoperatively, and data from the medical file concerning POPQ stage and obstetric and general history were obtained. Results: Thirty women (12.2%) were lost at follow up. Anatomical cystocele recurrence was present in 107/216 (49.5%), subjective recurrence in 19/208 (9.1%), and 39/219 (17.8%) patients met the criteria for composite outcome. The area under the receiver operating characteristic curves for anatomical, composite, and subjective recurrence were 65.5% (95% CI: 58.7-72.4), 55.8% (95% CI 47.3-64.3%, NS), and 55.1% (95% CI 45.1-65.2%), respectively. In the multivariable analysis, preoperative cystocele stage 3 or 4 and a complete levator defect on ultrasound were independent risk factors for anatomical recurrence. For composite recurrence, younger age and an active employment status were only risk factors in univariable analysis. No significant risk factors for subjective recurrence could be identified. Conclusions: This external validation study showed a moderate performance for a prediction model for anatomical recurrence. The model cannot be used for a composite or subjective outcome prediction because of poor performance. For composite and subjective recurrence, new prediction models need to be developed.

Value of pelvic examination in women with pelvic organ prolapse: A systematic review

BACKGROUND

Recent recommendations from the French High Authority of Health on pelvic organ prolapse (POP) management underline the value of a pelvic examination.

OBJECTIVES

The aim of this paper was to analyze the literature and identify the best evidence available regarding pelvic examination for women presenting prolapse-associated symptoms in terms of diagnosis and predictability of treatment success.

SEARCH STRATEGY

The databases were queried similarly using Medical Subject Headings (MeSH) and non-MeSH terms broadly related to pelvic examination and POP management.

SELECTION CRITERIA

We included studies assessing the diagnostic contribution of pelvic examination (correlation with symptoms) and its value for assessing the risk of pessary failure or recurrence after reconstructive surgery.

DATA COLLECTION AND ANALYSIS

We assessed peer-reviewed articles on PubMed, Embase, and Cochrane database up to May 2023. The methodological quality of all the included studies was assessed using the ROBINS-E or RoB2 tools.

MAIN RESULTS

In all, 67 studies were retained for the review. Prolapse-associated symptoms are poorly correlated with POP diagnosis. The symptom that is best correlated with the POP stage is the presence of a vaginal bulge (moderate to good correlation). The factors most strongly associated with the risk of recurrence after surgery or pessary failure are clinical: essentially a higher POP stage before surgery, levator ani muscle avulsion, and vaginal and genital measurements.

CONCLUSIONS

In women complaining of prolapse-associated symptoms, a pelvic examination (vaginal speculum and digital vaginal examination) can confirm the presence of POP and identify risk factors for treatment failure or recurrence after surgical management or pessary placement. A higher stage of POP and levator ani muscle avulsion-discernible on pelvic examination-are major risk factors for POP recurrence or treatment failure. These features must be taken into account in the treatment choice and discussed with the patient.

Laparoscopic Sacrohysteropexy for the Management of Uterovaginal Prolapse: a Pilot, Single-Center Experience from Saudi Arabia

Background

Laparoscopic sacrohysteropexy is an emerging uterine-preserving strategy for management of uterovaginal prolapse (UVP). The literature on laparoscopic sacrohysteropexy for management of UVP is very scarce from Saudi Arabia. This research examined the feasibility, clinical utility, and safety of laparoscopic sacrohysteropexy in a Saudi setting.

Methods

A retrospective study was conducted, including all patients who met the inclusion criteria. The laparoscopic sacrohysteropexy technique was adapted with modifications from the "Oxford hysteropexy". The primary endpoint was overall success, defined as anatomical success in all vaginal compartments (UVP grade 0 or 1 postoperatively). The secondary endpoint was the mean change in point C. Descriptive data were summarized with numbers and percentages, while numerical data used means ± standard deviations. Fisher's exact and Student's t tests were used for univariate analyses. Significant surgical outcome predictors were identified via logistic regression, with p <0.05 considered statistically significant.

Results

Overall, 21 patients met the inclusion criteria. The most frequent indication for laparoscopic sacrohysteropexy was UVP without anterior or posterior wall prolapse (n = 15, 71.4%), whereas the most frequent grade of UVP was grade III (n = 13, 61.9%). One patient (4.8%) required switch to laparotomy due to severe adhesions. No perioperative complications were recorded. The mean change in point C and hospital stay were 5.8 ± 2.1 (range: 0-8) and 1.4 ± 0.6 days (range: 1-3), respectively. Surgical success was achieved in 18 patients (85.7%). Only three patients experienced recurrences (one, two, and six months postoperatively). The mean change in point C was significantly higher in successful cases contrasted with the failed cases (6.5 versus 1.3).

Conclusion

Laparoscopic sacrohysteropexy for management of uterovaginal prolapse revealed technical feasibility, safety, and beneficial utility of the procedure. Further large-sized and multicentric investigations are important to gather additional pertinent information on laparoscopic sacrohysteropexy.

Three-year outcomes of a randomized clinical trial of perioperative vaginal estrogen as adjunct to native tissue vaginal apical prolapse repair

BACKGROUND

As the muscular and connective tissue components of the vagina are estrogen responsive, clinicians may recommend vaginal estrogen to optimize tissues preoperatively and as a possible means to reduce prolapse recurrence, but long-term effects of perioperative intravaginal estrogen on surgical prolapse management are uncertain.

OBJECTIVE

This study aimed to compare the efficacy of perioperative vaginal estrogen vs placebo cream in reducing composite surgical treatment failure 36 months after native tissue transvaginal prolapse repair.

STUDY DESIGN

This was an extended follow-up of a randomized superiority trial conducted at 3 tertiary US sites. Postmenopausal patients with bothersome anterior or apical vaginal prolapse were randomized 1:1 to 1-g conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally twice weekly for ≥5 weeks preoperatively and continued twice weekly for 12 months postoperatively. All participants underwent vaginal hysterectomy (if the uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The primary report's outcome was time to failure by 12 months postoperatively, defined by a composite outcome of objective prolapse of the anterior or posterior walls beyond the hymen or the vaginal apex descending below one-third the total vaginal length, subjective bulge symptoms, and/or retreatment. After 12 months, participants could choose to use-or not use-vaginal estrogen for atrophy symptom bother. The secondary outcomes included Pelvic Organ Prolapse Quantification points, subjective prolapse symptom severity using the Patient Global Impression of Severity and the Patient Global Impression of Improvement, and prolapse-specific subscales of the 20-Item Pelvic Floor Distress Inventory and the Pelvic Floor Impact Questionnaire-Short Form 7. Data were analyzed as intent to treat and "per protocol" (ie, ≥50% of expected cream use per medication diary).

RESULTS

Of 206 postmenopausal patients, 199 were randomized, and 186 underwent surgery. Moreover, 164 postmenopausal patients (88.2%) provided 36-month data. The mean age was 65.0 years (standard deviation, 6.7). The characteristics were similar at baseline between the groups. Composite surgical failure rates were not significantly different between the estrogen group and the placebo group through 36 months, with model-estimated failure rates of 32.6% (95% confidence interval, 21.6%-42.0%) and 26.8% (95% confidence interval, 15.8%-36.3%), respectively (adjusted hazard ratio, 1.55; 95% confidence interval, 0.90-2.66; P=.11). The results were similar for the per-protocol analysis. Objective failures were more common than subjective failures, combined objective and subjective failures, or retreatment. Using the Patient Global Impression of Improvement, 75 of 80 estrogen participants (94%) and 72 of 76 placebo participants (95%) providing 36-month data reported that they were much or very much better 36 months after surgery (P>.99). These data included reports from 51 of 55 "surgical failures." Pelvic Organ Prolapse Quantification measurements, Patient Global Impression of Severity scores, and prolapse subscale scores of the 20-Item Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire-Short Form 7 all significantly improved for both the estrogen and placebo groups from baseline to 36 months postoperatively without differences between the groups. Of the 160 participants providing data on vaginal estrogen usage at 36 months postoperatively, 40 of 82 participants (49%) originally assigned to the estrogen group were using prescribed vaginal estrogen, and 47 of 78 participants (60%) assigned to the placebo group were using vaginal estrogen (P=.15).

CONCLUSION

Adjunctive perioperative vaginal estrogen applied ≥5 weeks preoperatively and 12 months postoperatively did not improve surgical success rates 36 months after uterosacral or sacrospinous ligament suspension prolapse repair. Patient perception of improvement remained very high at 36 months.

Is It Possible to Diagnose Surgical Uterine Prolapse With Transperineal Ultrasound? Multicenter Validation of Diagnostic Software

OBJECTIVES

To validate an ultrasound software that uses transperineal ultrasound to diagnose uterine prolapse (UP).

METHODS

Multicenter, observational and prospective study with 155 patients that had indications for surgical intervention for dysfunctional pelvic floor pathology. Each patient underwent an examination with Pozzi tenaculum forceps was performed in the operating room with the patient anesthetized, followed by surgical correction of stages II-IV UP. Transperineal ultrasound was used to assess the difference in the pubis-uterine fundus measurement. With a multivariate logistic regression binary model (with the measurement ultrasound at rest, the Valsalva maneuver and age) using nonautomated methods to predict UP. With the purpose of evaluating the model, a table with coordinates of the receiver operating characteristic (ROC) curve, after which sensitivity and specificity were assessed.

RESULTS

A total of 153 patients were included (73 with a diagnosis of surgical UP). It was obtained from the AUC (0.89) of the probabilities predicted by the model (95% confidence interval, 0.84-0.95; P < .0005). Based on the ROC curve for the model, obtaining a sensitivity of 91.8% and a specificity of 72.7%, values that were superior to those for the clinical exam for surgical UP (sensitivity: 80.8%; specificity: 71.3%).

CONCLUSIONS

We validated software that uses transperineal ultrasound of the pelvic floor and patient age to generate a more reliable diagnosis of surgical UP than that obtained from clinical examinations.

Outcomes of robotic sacrocolpopexy

This review aimed to summarize the complications and surgical outcomes of robot-assisted sacrocolpopexy. Nineteen original articles on 1,440 robotic sacrocolpopexies were reviewed, and three systematic reviews and meta-analyses were summarized in terms of intraoperative, perioperative, postoperative, and/or surgical outcomes. Robotic sacrocolpopexy has demonstrated low overall complication rates and favorable surgical outcomes. Nevertheless, long-term follow-up outcomes regarding objective and/or subjective prolapse recurrence, reoperation rates, and mesh-related complications remain unclear. Further research is required to demonstrate whether the robotic approach for sacrocolpopexy is feasible or can become the modality of choice in the future when performing sacrocolpopexy.

Perioperative Vaginal Estrogen as Adjunct to Native Tissue Vaginal Apical Prolapse Repair: A Randomized Clinical Trial

Importance

Surgical repairs of apical/uterovaginal prolapse are commonly performed using native tissue pelvic ligaments as the point of attachment for the vaginal cuff after a hysterectomy. Clinicians may recommend vaginal estrogen in an effort to reduce prolapse recurrence, but the effects of intravaginal estrogen on surgical prolapse management are uncertain.

Objective

To compare the efficacy of perioperative vaginal estrogen vs placebo cream on prolapse recurrence following native tissue surgical prolapse repair.

Design, Setting, and Participants

This randomized superiority clinical trial was conducted at 3 tertiary US clinical sites (Texas, Alabama, Rhode Island). Postmenopausal women (N = 206) with bothersome anterior and apical vaginal prolapse interested in surgical repair were enrolled in urogynecology clinics between December 2016 and February 2020.

Interventions

The intervention was 1 g of conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally nightly for 2 weeks and then twice weekly to complete at least 5 weeks of application preoperatively; this continued twice weekly for 12 months postoperatively. Participants underwent a vaginal hysterectomy (if uterus present) and standardized apical fixation (either uterosacral or sacrospinous ligament fixation).

Main Outcomes and Measures

The primary outcome was time to failure of prolapse repair by 12 months after surgery defined by at least 1 of the following 3 outcomes: anatomical/objective prolapse of the anterior or posterior walls beyond the hymen or the apex descending more than one-third of the vaginal length, subjective vaginal bulge symptoms, or repeated prolapse treatment. Secondary outcomes included measures of urinary and sexual function, symptoms and signs of urogenital atrophy, and adverse events.

Results

Of 206 postmenopausal women, 199 were randomized and 186 underwent surgery. The mean (SD) age of participants was 65 (6.7) years. The primary outcome was not significantly different for women receiving vaginal estrogen vs placebo through 12 months: 12-month failure incidence of 19% (n = 20) for vaginal estrogen vs 9% (n = 10) for placebo (adjusted hazard ratio, 1.97 [95% CI, 0.92-4.22]), with the anatomic recurrence component being most common, rather than vaginal bulge symptoms or prolapse repeated treatment. Masked surgeon assessment of vaginal tissue quality and estrogenization was significantly better in the vaginal estrogen group at the time of the operation. In the subset of participants with at least moderately bothersome vaginal atrophy symptoms at baseline (n = 109), the vaginal atrophy score for most bothersome symptom was significantly better at 12 months with vaginal estrogen.

Conclusions and Relevance

Adjunctive perioperative vaginal estrogen application did not improve surgical success rates after native tissue transvaginal prolapse repair.

Manchester Procedure vs Sacrospinous Hysteropexy for Treatment of Uterine Descent: A Randomized Clinical Trial

Importance

In many countries, sacrospinous hysteropexy is the most commonly practiced uterus-preserving technique in women undergoing a first operation for pelvic organ prolapse. However, there are no direct comparisons of outcomes after sacrospinous hysteropexy vs an older technique, the Manchester procedure.

Objective

To compare success of sacrospinous hysteropexy vs the Manchester procedure for the surgical treatment of uterine descent.

Design, Setting, and Participants

Multicenter, noninferiority randomized clinical trial conducted in 26 hospitals in the Netherlands among 434 adult patients undergoing a first surgical treatment for uterine descent that did not protrude beyond the hymen.

Interventions

Participants were randomly assigned to undergo sacrospinous hysteropexy (n = 217) or Manchester procedure (n = 217).

Main Outcomes and Measures

The primary outcome was a composite outcome of success, defined as absence of pelvic organ prolapse beyond the hymen in any compartment evaluated by a standardized vaginal support quantification system, absence of bothersome bulge symptoms, and absence of prolapse retreatment (pessary or surgery) within 2 years after the operation. The predefined noninferiority margin was 9%. Secondary outcomes were anatomical and patient-reported outcomes, perioperative parameters, and surgery-related complications.

Results

Among 393 participants included in the as-randomized analysis (mean age, 61.7 years [SD, 9.1 years]), 151 of 196 (77.0%) in the sacrospinous hysteropexy group and 172 of 197 (87.3%) in the Manchester procedure group achieved the composite outcome of success. Sacrospinous hysteropexy did not meet the noninferiority criterion of -9% for the lower limit of the CI (risk difference, -10.3%; 95% CI, -17.8% to -2.8%; P = .63 for noninferiority). At 2-year follow-up, perioperative outcomes and patient-reported outcomes did not differ between the 2 groups.

Conclusions

Based on the composite outcome of surgical success 2 years after primary uterus-sparing pelvic organ prolapse surgery for uterine descent, these results support a finding that sacrospinous hysteropexy is inferior to the Manchester procedure.

The association between smoking status and post-operative complications in pelvic organ prolapse corrective surgeries

INTRODUCTION AND HYPOTHESIS

Tobacco is a known risk factor for pelvic organ prolapse (POP) as well as postoperative complications in general surgery procedures. Very little is known regarding the impact of tobacco use on postoperative outcomes in POP-correcting procedures, however. We hypothesize that tobacco use will be associated with an increased risk of postoperative complications in these procedures.

METHODS

This study utilized the National Surgical Quality Improvement Program (NSQIP) database for the years 2012-2020. Patients who underwent POP-correcting procedures were identified using current procedural terminology (CPT) codes. Baseline characteristics between the patient populations were compared using chi-square and one-way ANOVA tests as indicated. Binary logistic regression was used to evaluate the incidence of postoperative complications based on smoking status while controlling for demographic and clinical factors.

RESULTS

This study included 43,406 total patients, 39,614 non-smokers and 3792 smokers. Postoperative complications including deep wound infections (P < 0.001), intraperitoneal infections (P = 0.003), wound dehiscence (P = 0.014), urinary tract infections (P = 0.029), and hospital readmissions (P < 0.001) were significantly higher in patients who smoke than those who do not. Further evaluation of patients who did not undergo mesh placement intraoperatively and those who solely underwent vaginal procedures showed similar trends.

CONCLUSIONS

This study demonstrates a higher incidence of postoperative complications after POP-correcting procedures in patients with who smoke. Wound complications, urinary tract infections, and hospital readmission confer a considerable amount of risk to patient outcomes in addition to significant healthcare cost. Consideration should be given to smoking status in preoperative evaluation and counseling before these procedures.

Surgical outcomes in patients aged 70 years and older following uterosacral ligament suspension: a comparative study

PURPOSE

The number of elderly patients bothered by pelvic organ prolapse symptoms is growing rapidly. The aim of this study was to evaluate the relationship between age and surgical outcomes in women undergoing uterosacral ligament suspension for treatment of apical prolapse.

METHODS

We performed a retrospective cohort study including women who underwent uterosacral ligament suspension between 2010 and 2020. The cohort was divided into two groups: (1) Patients 70 years or older; (2) Patients under the age of 70. Outcome measures included clinical, anatomical, and composite outcomes as well as patient satisfaction.

RESULTS

A total of 271 patients were included in the final analysis. Of them 209 patients were under age 70 and 62 patients 70 years or older. Mean age was 59 ± 6 vs. 73 ± 3 for the young and elderly age groups, respectively. Clinical success was high for both groups, reaching 94% vs. 89% for elderly and young patients, respectively (p = 0.34). Anatomical and composite outcome success were higher in the young age group (76% vs. 56%, p < 0.01 and 70% vs. 54%, p = 0.02, respectively); however, following multivariate analysis these differences were no longer statistically significant. Following multivariate logistic regression analysis for the dependent parameter of anatomical success, increased pre-operative genital hiatus and vaginal surgical route were associated with anatomical failure while performing a concomitant posterior colporrhaphy increased likelihood for anatomical success.

CONCLUSION

Women over the age of 70 undergoing uterosacral ligament suspension for treatment of apical prolapse have comparable outcomes to younger patients.
