Complications of mid urethral slings: important outcomes for future clinical trials

Extended Treatment-dose Antibiotic Therapy vs Low-dose Prophylaxis for the Management of Recurrent Uncomplicated Urinary Tract Infections in Peri- and Post-menopausal Women

OBJECTIVE

To assess treatment efficacy over 1year in women with recurrent urinary tract infection (UTI) receiving extended treatment-strength antibiotics compared to standard low-dose prophylactic antibiotic regimens.

METHODS

A retrospective cohort study of adult women presenting with acute uncomplicated UTI between January 1, 2018 and October 1, 2020 meeting recurrent UTI criteria (≥2 in 6months or ≥3 in 1year). Women were offered either: (1) treatment-strength antibiotic therapy for 1month; or (2) up to 7days of treatment-strength antibiotics followed by ≥3-month of low-dose prophylactic antibiotics. We excluded those with complicated UTI. The primary outcome was one or more symptomatic, culture-proven UTIs within 12months. Multivariable logistic regression assessed differences in the primary outcome while controlling for potential confounders.

RESULTS

Among the 246 patients, women receiving extended treatment dose antibiotics (n=43) had a significantly lower risk of experiencing subsequent UTI within 1year when compared to those receiving standard prophylactic dosing for ≥3-month (n=203) (rate 34.9% vs 59.6%; P<.01). This significant risk reduction was maintained in logistic regression analyses while controlling for potentially confounding variables (aOR 0.42; 95% CI 0.20, 0.89).

CONCLUSION

Women treated with a 1-month course of treatment-strength antibiotics had a significantly lower risk of subsequent UTI within 12months compared to women receiving ≥3-month of prophylactic antibiotics. These retrospective data preliminarily suggest that extended treatment-strength antibiotic dosing may provide therapeutic benefit while reducing overall cumulative antibiotic dose and duration. This innovative approach warrants further evaluation in randomized trials.

Management of patients with mesh perforation into viscus following pelvic mesh surgery

PURPOSE

Pelvic mesh has been used for the treatment of pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Between 3 and 20% suffer complications with debilitating long-term outcomes. Uncommon complications include mesh perforation into viscus however there is minimal published data regarding outcomes following surgical management.

METHODS

A retrospective observational study of patients with diagnosis of mesh in viscus at three tertiary urogynaecology units was performed to report on clinical outcomes following surgical management.

RESULTS

Fifty-eight patients were diagnosed with mesh in viscus following cystourethroscopy and thorough examination of vagina/rectum. Mesh involved included mid-urethral slings-retropubic (36.9%), transobturator (18.5%), single incision slings (10.8%); transvaginal POP mesh (15.4%); sacrocolpopexy (13.8%); uncertain type (4.6%). Viscus involved included bladder (39.7%), urethra (50%), bladder and urethra (3.4%), and rectum (6.9%). Main presenting symptoms included mixed urinary incontinence (UI) (75.9%), recurrent urinary tract infections (rUTIs) (48.3%) and rectal/pelvic pain (56.9%). Fifty-one patients underwent mesh excision and viscus repair, with successful repair in all (100%). 48% had complete mesh excision. Mean follow up was 9.5 months (range 0.5-96 months). Post-operatively, there was a statistically significant reduction in rUTIs (p = 0.0004) as well as pain (p = 0.000005). None had recurrent mesh erosion, lower genitourinary tract fistula or wound breakdown.

CONCLUSIONS

All patients required thorough examination and cystourethroscopy for diagnosis. Surgical management of mesh in viscus appears to have low morbidity and is shown to reduce symptoms of rUTIs and pain as well as risk of recurrent mesh erosion and fistulae.

Magnetoactive elastomer-based dynamic urethral support device for stress urinary incontinence

Stress urinary incontinence (SUI) is the involuntary leakage of urine in response to increased intra-abdominal pressure during episodes of exertion. A common treatment method for SUI is sling implantation underneath the urethra to provide support. Most current sling procedures, however, cannot adjust urethral tension postoperatively. To address this limitation, we designed a soft magnetoactive elastomer (MAE) device capable of changing shape in response to moderate magnetic fields. To ensure shape change after fibrotic scar tissue encapsulation, MAE devices were embedded in agar gels with different stiffnesses, and their shape change was studied in response to up to 200 mT magnetic fields. A simple in vitro model of the lower urinary tract was designed to study device performance. Flow time was measured as a function of pressure in the simulated bladder as the model system leaked before and after activating sling with a hand-held magnet. MAE devices embedded in agar gel (100 kPa) in hammock-like configuration achieved 4.7% ± 1.1% change in height. Devices with silica-coated magnetic particles showed minimal loss in mass after two weeks in accelerated oxidative (2.36% ± 1.55%) and hydrolytic (0.58% ± 0.25%) conditions. Placing a sling under the model urethra provided urethral support; thus, increasing its resistance to flow. Normalized flow time significantly reduced from 1.56 ± 0.18 to 1.11 ± 0.16 when magnetic field was applied, indicating urethral support modulation at 60 cm-H2O. This dynamic sling, powered externally with physiologically safe magnetic fields, allowed for urethral support modulation in a model of the lower urinary tract. STATEMENT OF SIGNIFICANCE: Stress urinary incontinence (SUI) affects up to half the adult women during their lifetime, and slings are commonly used to treat severe cases. While sling implantation is minimally invasive and offers moderate to high cure rates, long-term sling complications, such as urine retention, remain a significant concern. Available adjustable SUI devices often require invasive surgeries, implantable electronics, and multiple mechanical components, increasing the overall invasiveness. Here, we report a proof of concept for using shape-morphing biomaterials to fabricate a dynamic device that can provide continence support and be triggered to change shape, enabling complete voiding. Such a dynamic device may prevent many complications associated with traditional slings and improve quality of life for women suffering from severe SUI.

Midurethral Sling Mesh Exposure Confers a High Risk of Persistent Stress Urinary Incontinence

INTRODUCTION AND HYPOTHESIS

The objective was to investigate the relationship between mesh exposure and persistent stress urinary incontinence (SUI) post-midurethral sling (MUS) surgery.

METHODS

Extensive data collection including patient demographics, obstetric history, existing medical conditions, previous surgeries, and surgical outcomes, encompassing both perioperative and postoperative complications.

RESULTS

Out of 456 patients who underwent the MUS procedure within the specified period, the persistence of SUI was noted in 6.4% of cases. Mesh exposure was observed in 8.8% of these cases. Notably, 25% of patients with mesh exposure suffered from persistent SUI, in stark contrast to 4.6% of those without mesh exposure (p < 0.0001). Further, multivariate analysis indicated that patients with mesh exposure had an approximately 6.5-fold increased likelihood (95% CI: 2.71-15.44) of experiencing persistent SUI compared with those without mesh exposure.

CONCLUSIONS

Mesh exposure is a significant independent risk factor for persistent SUI post-MUS surgery. Patients with mesh exposure are about 6.5 times more prone to persistent SUI than those without. Although mesh exposure is typically managed with expectant measures, vaginal estrogen or mesh excision, current evidence does not support surgical revision of MUS affected by mesh exposure or additional incontinence procedures during mesh excision.

Platelet-Rich Plasma for the Treatment of Stress Urinary Incontinence-A Randomized Trial

IMPORTANCE

Urinary incontinence affects millions of women worldwide.

OBJECTIVE

The aim of the current study was to evaluate the efficacy and safety of periurethral platelet-rich plasma (PRP) injections in women with stress urinary incontinence (SUI).

STUDY DESIGN

This was a single-center, double-blind, randomized sham-controlled trial. Fifty participants with SUI and urodynamic stress incontinence were randomized in 2 equally sized groups. Women in the PRP group received 2 PRP injections at 3 levels of the urethra at 4- to 6-week intervals. Women in the sham group were injected with sodium chloride 0.9%. At baseline, participants underwent urodynamic studies and a 1-hour pad test and completed the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), the Patient Global Impression Scale of Improvement, and the King's Health Questionnaire. At follow-up visits (1, 3, and 6 months), women underwent the 1-hour pad test and completed the King's Health Questionnaire and the ICIQ-FLUTS. Primary outcome was the subjective evaluation as indicated by the response to question 11a of the ICIQ-FLUTS questionnaire. Secondary outcomes included scores of questionnaires and urine loss assessed on the 1-hour pad test. The level of discomfort during injections and any adverse events were also evaluated.

RESULTS

During follow-up, the mean score of the 11a question decreased significantly in the PRP group compared with sham. Subjective cure was significantly higher in the PRP group (32% vs 4%, P < 0.001). A significant reduction of urine loss assessed on the 1-hour pad test was observed in the PRP group compared with the sham group at 6-month follow-up. No adverse events were observed.

CONCLUSIONS

Periurethral PRP injections were superior to sham injections in improving SUI symptoms with an excellent safety profile.

Advancements in scaffold for treating ligament injuries; in vitro evaluation

Tendon/ligament (T/L) injuries are a worldwide health problem that affects millions of people annually. Due to the characteristics of tendons, the natural rehabilitation of their injuries is a very complex and lengthy process. Surgical treatment of a T/L injury frequently necessitates using autologous or allogeneic grafts or synthetic materials. Nonetheless, these alternatives have limitations in terms of mechanical properties and histocompatibility, and they do not permit the restoration of the original biological function of the tissue, which can negatively impact the patient's quality of life. It is crucial to find biological materials that possess the necessary properties for the successful surgical treatment of tissues and organs. In recent years, the in vitro regeneration of tissues and organs from stem cells has emerged as a promising approach for preparing autologous tissue and organs, and cell culture scaffolds play a critical role in this process. However, the biological traits and serviceability of different materials used for cell culture scaffolds vary significantly, which can impact the properties of the cultured tissues. Therefore, this review aims to analyze the differences in the biological properties and suitability of various materials based on scaffold characteristics such as cell compatibility, degradability, textile technologies, fiber arrangement, pore size, and porosity. This comprehensive analysis provides valuable insights to aid in the selection of appropriate scaffolds for in vitro tissue and organ culture.

From thigh to pelvis: female genital prolapse repair with an autologous semitendinosus tendon transplant : Data of the German multicenter trial

INTRODUCTION AND HYPOTHESIS

The use of synthetic mesh for prolapse and incontinence surgery is discussed controversially and in several countries is either no longer used or permissible. Previous approaches with autologous tissue did not show from a patient´s perspective convincing long-term results. As there have been repeatedly significant complications with synthetic mesh, a new approach is urgently needed. During orthopedics and trauma surgeries, tendons from the thigh have been used for decades to replace cruciate ligament. The procedure of tendon removal from the thigh is fast, easy to learn and morbidity is low. In addition, a long-term durability of the transplant ought to be expected. The objective of this investigation was to show our experience with a semitendinosus tendon instead of a mesh for genital prolapse repair.

METHOD

After the first successful attempts using such tendons in cervicosacropexy and pectopexy in patients with genital prolapse, we initiated a national multicenter study in 2020. Five German hospitals participated in order to determine the feasibility of cervicosacropexy with tendon tissue instead of mesh.

RESULT

Up until now, we have operated and observed 113 patients for at least 6 months and have seen stable results in terms of fixation of the apical compartment. The expected low morbidity at the donor site was also confirmed through subjective assessment of the patients (Knee and Osteoarthritis Outcome Score). Improvement of quality of life was confirmed after the procedure with the Short Form Health Survey 12, Version 2.0. The results of this multicenter study showed that the desired elevation of the apical compartment with tendon tissue can be achieved with low morbidity and without a synthetic mesh.

CONCLUSION

Women with uterine prolapse can be treated minimally invasively and with very low morbidity by using the semitendinosus tendon. The involvement of multiple (five) medical centers confirms that the technique is easy to learn and be transferred to other clinical centers.

Does trocar puncture of the bladder during midurethral sling impact postoperative urinary storage and voiding symptoms?

INTRODUCTION AND HYPOTHESIS

The incidence of trocar bladder puncture during midurethral sling (MUS) surgery varies widely. We aim to further characterize risk factors for bladder puncture and examine its long-term impact on storage and emptying.

METHODS

This is an Institutional Review Board-approved, retrospective chart review of women who underwent MUS surgery at our institution from 2004 to 2018 with ≥12 months of follow-up. Unless prolonged catheterization was necessary, a voiding trial was performed prior to discharge, or the next morning in outpatients, regardless of puncture. Preoperative and postoperative details were obtained from office charts and operative records.

RESULTS

Of 1,500 women, 1,063 (71%) had retropubic (RP) and 437 (29%) had transobturator MUS surgery. Mean follow-up was 34 months. Thirty-five women (2.3%) sustained a bladder puncture. RP approach and lower BMI were significantly associated with puncture. No statistical association was found between bladder puncture and age, previous pelvic surgery, or concomitant surgery. Mean day of discharge and day of successful voiding trial were not statistically different between the puncture and nonpuncture groups. There was no statistically significant difference in de novo storage and emptying symptoms between the two groups. Fifteen women in the puncture group had cystoscopy during follow-up and none had bladder exposure. Level of the resident performing trocar passage was not associated with bladder puncture.

CONCLUSIONS

Lower BMI and RP approach are associated with bladder puncture during MUS surgery. Bladder puncture is not associated with additional perioperative complications, long-term urinary storage/voiding sequelae, or delayed bladder sling exposure. Standardized training minimizes bladder punctures in trainees of all levels.

Single Incision Mini-Sling Versus Mid-Urethral Sling (Transobturator/Retropubic) in Females With Stress Urinary Incontinence: A Systematic Review and Meta-Analysis

Stress urine incontinence (SUI) is most common in middle-aged women and the second most common in those over 75. SUI causes significant discomfort and suffering for patients and has a considerable financial impact on the healthcare system. Conservative approaches are recommended as the first step in treatment. However, surgery is often necessary to improve a patient's quality of life due to the high failure rate of conservative treatments. A thorough literature review of studies published before March 2023 was conducted on the safety and effectiveness of single-incision mini slings (SIMS) and standard mid-urethral slings (MUS). PubMed, Embase, Cochrane Library, and Elsevier's ScienceDirect were used to retrieve the studies. Two reviewers independently searched and evaluated the data based on inclusion and exclusion criteria. Review Manager 5.4 software was used for meta-analysis. Included were seventeen studies involving 3,503 female SUI patients without intrinsic sphincter deficiency (ISD) or mixed urinary incontinence. According to the results of our meta-analysis, the clinical efficacy of SIMS is comparable to that of MUS in terms of objective cure rate (RR: 0.99; 95% CI: 0.95 to 1.03, p: 0.66, I2: 29%). In contrast, it increases the post-procedure International Consultation on Incontinence Questionnaire (ICIQ) score (WMD: 0.08; 95% CI: -0.08 to 0.08). CI: -0.02 to 0.18, p: 0.11, I2: 55%) and improves the PGI-I score to a greater extent (RR: 1.04; 95% CI: 0.96 to 1.08, p: 0.36, I2: 76%). In contrast, there is no difference between the two groups regarding patient satisfaction (RR: 0.96; 95% CI: 0.92 to 1.01, p: 0.16, I2: 0%) and Sandvik score reduction (RR: 0.98; 95% CI: 0.94 to 1.02, p: 0.35, I2: 0%). In conclusion, single-incision mid-urethral slings (SIMS) are as effective as mid-urethral slings (MUS) for treating pure stress urinary incontinence (SUI) without intrinsic sphincter deficiency (ISD), with a shorter operation time. However, the SIMS procedure has a higher incidence of dyspareunia. At the same time, bladder perforation, mesh-related complications, pelvic/groin pain, urinary tract infection (UTI), worsening urgency, dysuria, and pain score are less likely to occur with SIMS. Only the decrease in pelvic/groin pain was statistically significant.

Surgical teaching of the retropubic midurethral sling: a virtual reality training system

INTRODUCTION AND HYPOTHESIS

The objective is to develop a low-risk, cost-effective method to teach procedures that require learning by feel and high-volume pattern recognition, starting with the midurethral sling.

METHODS

This video describes the creation of a virtual reality model utilizing de-identified patient data, artificial intelligence algorithms and haptics; and demonstrates the use of the training system for trocar passage of the retropubic midurethral sling procedure.

RESULTS

This innovative system overcomes the lack of visualization and "blind" nature of sling surgery. Novel artificial intelligence provides high accuracy of anatomical landmarks and a realistic 3D environment. The trainee benefits from haptic and visual alerts for real-time feedback on the trocar insertion pathway and scoring to develop competency.

CONCLUSION

This is one of the first noncadaveric, nonstatic models available in the field. It allows for multiple low-risk exercises and provides more surgeons with training outside the operating room, at their own institution, and avoids the need for patient subjects. Training can be disseminated at a significantly lower cost and greater convenience than remote cadaver laboratories or intraoperative observation and has a higher fidelity than available static models, particularly after multiple passes. This has implications not only for retropubic midurethral slings but also for urogynecological and "blind" surgery as a whole.

Liquid crystal elastomer based dynamic device for urethral support: Potential treatment for stress urinary incontinence

Stress urinary incontinence (SUI) is characterized by the involuntary loss of urine due to increased intra-abdominal pressure during coughing, sneezing, or exercising. SUI affects 20-40% of the female population and is exacerbated by aging. Severe SUI is commonly treated with surgical implantation of an autologous or a synthetic sling underneath the urethra for support. These slings, however, are static, and their tension cannot be non-invasively adjusted, if needed, after implantation. This study reports the fabrication of a novel device based on liquid crystal elastomers (LCEs) capable of changing shape in response to temperature increase induced by transcutaneous IR light. The shape change of the LCE-based device was characterized in a scar tissue phantom model. An in vitro urinary tract model was designed to study the efficacy of the LCE-based device to support continence and adjust sling tension with IR illumination. Finally, the device was acutely implanted and tested for induced tension changes in female multiparous New Zealand white rabbits. The LCE device achieved 5.6% ± 1.1% actuation when embedded in an agar gel with an elastic modulus of 100 kPa. The corresponding device temperature was 44.9 °C ± 0.4 °C, and the surrounding agar temperature stayed at 42.1 °C ± 0.4 °C. Leaking time in the in vitro urinary tract model significantly decreased (p < 0.0001) when an LCE-based cuff was sutured around the model urethra from 5.2min ± 1min to 2min ±0.5min when the cuff was illuminated with IR light. Normalized leak point force (LPF) increased significantly (p = 0.01) with the implantation of an LCE-CB cuff around the bladder neck of multiparous rabbits. It decreased significantly (p = 0.023) when the device was actuated via IR light illumination. These results demonstrate that LCE material could be used to fabricate a dynamic device for treating SUI in women.

Assessment of Adverse Events in a Matched Cohort of Women Undergoing Concurrent Midurethral Sling at the Time of Minimally Invasive Benign Gynecologic Surgery

IMPORTANCE

Procedures for stress urinary incontinence and benign gynecologic surgery are often performed concurrently, and associated complication rates have previously been unexplored.

OBJECTIVE

The aim of this study was to compare postoperative complication rates between women undergoing midurethral sling (MUS) placement at the time of benign gynecologic surgery and those undergoing MUS alone.

STUDY DESIGN

This was a retrospective matched cohort study of women undergoing MUS with or without concurrent minimally invasive benign gynecologic surgery from January 2010 through December 2020. Eligible women undergoing concurrent surgery were matched to a cohort of women undergoing MUS placement alone. The electronic medical record was queried for demographic and perioperative/postoperative data up to 12 months after surgery.

RESULTS

Thirty-eight women met inclusion criteria for the concurrent group, and 152 women were matched accordingly. The overall adverse event rate was 39.5% (95% confidence interval [CI], 0.25-0.55) for the concurrent group and 24.3% (95% CI, 0.18-0.32) for the MUS-only group ( P = 0.05). Adverse events with Clavien-Dindo grade ≤ 2 were higher in the concurrent group (Clavien-Dindo Grade 1: 5% vs 0%, P = 0.04; Clavien-Dindo Grade 2: 16% vs 6%, P = 0.04), as was composite postoperative resource utilization (76% vs 49%, P = 0.003). Mesh exposure ( P = 0.03) and sling lysis/excision rates ( P = 0.02) were higher in the concurrent group. On logistic regression, concurrent surgery cases remained significantly associated with sling mesh erosion (adjusted odds ratio, 12.6; 95% CI, 1.4-116.4).

CONCLUSIONS

Midurethral sling placement at the time of minimally invasive benign gynecologic surgery is safe but is associated with a higher incidence of postoperative hospital resource utilization and sling mesh extrusion, and a need for revision.

Home-based noninvasive pelvic floor muscle training device to assist women in performing Kegel exercise in the management of stress urinary incontinence

BACKGROUND

Stress urinary incontinence (SUI) is a major health problem affecting approximately 50% of the female population over 45 years of age. We evaluated the therapeutic effects of a home-based non-invasive wireless sensor pelvic floor muscle training (PFMT) device with assisted Kegel exercise for SUI.

METHODS

We included 60 women 40 to 60 years of age who were diagnosed with urodynamic SUI (mean pad test, 10.52 g). The PFMT device applicator was clamped on the upper inner thigh, and the patients could self-train at home. The signal was recorded and delivered to a 3G/4G smartphone via Bluetooth, which also allows guided feedback via the smartphone's voice. To evaluate the therapeutic effect, all patients completed the following questionnaires: a 3-day bladder diary, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the Urogenital Distress Inventory-Short Form, and the Incontinence Impact Questionnaire-7 (IIQ-7). One-hour pad test measurements were performed before the test (M0) and at 1 (M1), 2 months (M2), and 3 months (M3) after the PFMT device-assisted Kegel exercise.

RESULTS

The 1-hour pad test and the scores of the ICIQ-SF, UDI-6, and IIQ-7 questionnaires were improved at M1, M2, and M3, compared with the M0 values. The mean value of the post-voiding residual urine (PVR) significantly decreased at M2 and M3. The subjective and objective improvement rates at M3 were 80% and 72%, respectively.

CONCLUSION

The data demonstrated that 3 months of Kegel exercise assisted with a home-based PFMT device improved the number and severity of episodes, PVR, and quality of life in patients with SUI, suggesting that this device might serve as an alternative non-invasive therapy for mild and moderate SUI.

Symptom Resolution and Recurrent Urinary Incontinence Following Removal of Painful Midurethral Slings

OBJECTIVE

To evaluate pain improvement and recurrent stress incontinence (SUI) following painful synthetic midurethral sling (MUS) removal.

METHODS

We conducted a retrospective review of patients who underwent synthetic MUS removal at our institution from 2009-2016 for the indication of pain. We recorded sling type (transobturator vs retropubic), complete vs partial removal, and presenting symptoms. Postoperative pain improvement was categorized as resolved (pain resolved, requiring no further therapy), improved (pain less bothersome, may require further therapy), or unresolved (no/minimal improvement, requiring further management). Recurrent incontinence and further reconstructive procedures were assessed.

RESULTS

87 patients (49 complete and 38 partial removal) with pain as the primary indication for removal were included. Median age at intervention was 54 years with median follow-up of 8 months. Overall, pain improved or resolved in 78.1% of cases. Complete removal was associated with significantly greater percentage of pain resolution (63.3%) compared to partial removal (26.3%) (P = 0.002) regardless of sling type. No significant differences in recurrent SUI were noted in complete vs partial removal. Additional reconstructive procedures were performed in 28 patients, most commonly sling placement, with no significant difference in complete (20.4%) vs partial (28.9%) removal groups (P = 0.36). The overall complication rate was low (5.7%), a majority of which were transfusions (4.6%).

CONCLUSION

Following MUS removal, most patients experienced resolution or improvement of pain. Complete sling removal was associated with significantly greater percentage of pain resolution compared to partial removal in both retropubic and transobturator slings. Rates of recurrent SUI and reintervention for SUI were not related to the extent of sling removal.

[Voiding dysfunction after TVT: A 20-year experience TVT-placement under local anesthesia and sedation]

BACKGROUND

Trans-vaginal tape has become the gold standard for the cure of urinary stress incontinence, but post-operative voiding dysfunction is frequently reported. The purpose of this study is to assess the incidence of voiding dysfunction, dysuria, chronic urinary retention, and necessity of reoperation after retropubic TVT placement under local anaesthesia and sedation.

MATERIAL AND METHOD

We perform a retrospective study of a cohort of patient treated with the placement of a retropubic TVT under local anaesthesia and sedation between 1999 and 2019 for a SUI. Post-operative voiding dysfunction and necessity of reoperation were reviewed to access the principal aim of this study.

RESULTS

Three hundred and two patients who met the eligibility criteria were included in the study. At 3 months, the dysuria rate and chronic urinary retention rate was 4.3% and 1%. At 12 months it was 2.6% and 0.3% respectively. The 12-month sling section rate was 1% and long-term self-catherization rate was 0.3%. The objective cure rate was 93% and subjective cure was 92%.

CONCLUSION

TVT placement under local anaesthesia and sedation resulted in few voiding dysfunctions at medium/long-term, necessity of re-operation for refractory obstructive disorder and well functional results. Even if these results support more frequent use of this type of anaesthesia, it would be interesting to be able to follow them in a prospective study to conclude.

[Complications of mid-urethral sling - A review from the Committee for Female Urology and Pelviperineology for the French Association of Urology]

INTRODUCTION

Placement of a mid-urethral sling is the gold standard in the surgical management of stress urinary incontinence in women in France. The cure rate of this material is no longer to be demonstrated, but the per- and post-operative complications are currently the subject of a growing controversy not only in Europe but also across the Channel and across the Atlantic, having led to the modification of operative indications. In France, recommendations are also evolving with a stricter framework for indications for surgery by multidisciplinary consultation meeting and an obligation for postoperative follow-up in the short and long term.

OBJECTIVES

In this context, CUROPF realized a review of the literature bringing together the available scientific evidence concerning the occurrence of per- and post-operative complications relating to the installation of mid urethral sling. The bibliographic search was carried out using the Medline database and 123 articles were selected.

RESULTS

Analysis of the data highlights various complications, depending on the implanted material, the patient and the indication for surgery. The retro-pubic mid urethral sling provides more bladder erosion during surgery (up to 14%), more suprapubic pain (up to 4%) and more acute urinary retention (up to 19,7%) and postoperative dysuria (up to 26%). The trans obturator mid-urethral sling is responsible for more vaginal erosion during the operation (up to 10,9%), more lower limb pain of neurological origin (up to 26,7%). The risk of developing over active bladder is similar in both procedures (up to 33%). But these risks of complications must be balanced by the strong impact of urinary incontinence surgery on the overall quality of life of these women.

CONCLUSION

Thus, surgical failure and long term complications exist but should not limit the surgical management of stress urinary incontinence with mid urethral tape. Women should be treated with individualized decision-making process and long-term follow -up is necessary.

The Use of Platelet-rich Plasma as a Novel Nonsurgical Treatment of the Female Stress Urinary Incontinence: A Prospective Pilot Study

OBJECTIVES

The aim of the study was to evaluate the efficacy and safety of platelet-rich plasma (PRP) for the treatment of stress urinary incontinence (SUI).

METHODS

This was a prospective observational pilot study conducted in a tertiary referral unit, enrolling women with SUI booked for SUI surgery. A total of 20 consecutive women met the inclusion criteria and attended all follow-ups. All participants underwent 2 PRP injections into the lower one third of the anterior vaginal wall at 4- to 6-week intervals. At baseline, they underwent urodynamic studies, a 1-hour pad test, and completed the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms and King's Health Questionnaire. At follow-up visits (1, 3, and 6 months), patients underwent the 1-hour pad test and completed the King's Health Questionnaire, International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms, and Patient Global Impression Scale of Improvement. Primary outcome was to evaluate posttreatment SUI. Secondary outcomes included assessment of patient-reported questionnaires, assessment of urine loss (1-hour pad test), and the level of discomfort during injections (visual analog scale score). Statistical analysis was performed before PRP and 1, 3, and 6 months after the last treatment.

RESULTS

A significant improvement in SUI symptoms was observed 3 months after treatment with a further improvement at 6 months. A mean reduction of 50.2% in urine loss was observed in the 1-hour pad test. At the 6-month follow-up, 80.0% of women reported to be at least improved. No adverse effects were observed.

CONCLUSIONS

Platelet-rich plasma injections were both effective and safe at least in the short term and could be offered as an alternative outpatient procedure for the treatment of SUI. However, these encouraging findings warrant further investigation with randomized controlled trials.

A retrospective analysis of perioperative complications associated with retropubic tension-free vaginal tape in 960 women

Purpose

The purpose is to analyse perioperative complications associated with the retropubic tension-free vaginal tape (TVT) procedure and their management.

Methods

This retrospective, monocentric cohort study included 960 women after retropubic TVT procedure performed by one surgeon from 2011 to 2016. Complications were identified up to 6 weeks after the procedure, divided into specific and general complications and classified based on the Clavien–Dindo (CD) Classification. A visit 6 weeks after the surgical procedure was attended by all patients.

Results

77 complications, of which 74 occurred postoperatively and 3 intraoperatively, affecting 72 (7.5%) out of 960 women. Urinary retention and voiding problems were the most common complication. The mean age of women suffering complications was 3.4 years higher in comparison to the mean age of women without complications (p = 0.036). The Body Mass Index (BMI) of the group of women with perioperative complications had an average BMI which was 0.5 kg/m² lower than the average BMI of the women without complications. 22 (12.8%) out of 172 women with recurrent stress incontinence had postoperative complications, of which 21 were related to the TVT.

Conclusion

The retropubic TVT is a surgical procedure associated with a low number of perioperative complications, even in the group of elderly and overweight women, as well as in cases of recurrent stress incontinence.

Medical malpractice in stress urinary incontinence management: A 30-year legal database review

BACKGROUND

The purpose of this study is to investigate the most common reasons for and judicial outcomes of malpractice claims related to stress urinary incontinence (SUI) management.

MATERIALS AND METHODS

Using the Westlaw database, a search was performed using the terms "medical malpractice" or "negligence" in combination with "stress incontinence" or "stress urinary incontinence" between January 1, 1990 and January 1, 2020. Extracted information included trial date, demographic information, defendant profession, procedure performed, procedure complications, alleged malpractice, trial outcome, and monetary award. Data were analyzed using descriptive statistics.

RESULTS

The Westlaw search yielded 79 case results. Of the cases, 70.4% (n = 38/54) had a defense verdict, 22.2% (n = 12/54) had a plaintiff verdict, and 7.4% (n = 4/54) were settled. The most commonly implicated procedure was mid-urethral sling (63.2%, n = 36/57). Among the plaintiffs, 48.4% (n = 61/126) claimed negligence in preoperative care, 33.3% (n = 42/126) claimed negligence in surgical performance, and 18.3% (n = 23/126) claimed negligence in postoperative care. Lack of informed consent was the most common complaint related to negligence in preoperative care (42.6%, n = 26/61). The average indemnity payment was $1,253,644 for preoperative care negligence, $1,254,491 for surgical performance negligence, and $2,239,198 for postoperative care negligence. Of the defendants, 63.4% (n = 52) were gynecologists and 36.6% (n = 30) were urologists.

CONCLUSIONS

Negligent preoperative care, with a particular emphasis on failure to obtain informed consent, and negligent surgical performance are the leading causes of malpractice claims during SUI management. Mid-urethral sling was the most commonly litigated procedure. This study highlights key factors to consider in minimizing malpractice risk during SUI management.

Retropubic mid-urethral slings and de novo urinary urgency and frequency: The role of retropubic hematomas

AIMS

This is a prospective cohort study comparing de novo lower urinary tract symptoms (LUTS) in subjects undergoing a retropubic mid-urethral sling who either did or did not develop a postoperative retropubic hematoma within 6 weeks of surgery. The secondary objective was to measure the incidence and prevalence of retropubic hematomas, and subject characteristics associated with retropubic hematomas.

METHODS

Eligible subjects were recruited before undergoing a retropubic mid-urethral sling with or without concurrent pelvic reconstructive surgery. Validated urinary symptom questionnaires were completed before surgery and at 6 weeks postoperatively. An abdominal ultrasound was used to establish baseline lower urinary tract imaging. Ultrasound was repeated immediately after surgery and 6 weeks later to assess for the presence of retropubic hematomas.

RESULTS

Ninety-four subjects were enrolled. Baseline urgency and frequency were measured in 35% (33/93) of subjects. At 6 weeks postoperatively, 2% (1/52) had de novo LUTS which were not associated with a retropubic hematoma at any time. Immediately after surgery, the incidence of retropubic hematomas was 17% (16/94) while the prevalence of retropubic hematomas 6 weeks after surgery was 4% (3/75). There was no significant difference in the change in hemoglobin before and after surgery between those with and without postoperative retropubic hematomas.

CONCLUSIONS

There is no significant association with de novo LUTS and retropubic hematomas. Though there is a 17% incidence of retropubic hematomas detected immediately after surgery, those with hematomas who were not lost to follow-up resolved by the 6-week postoperative visit and is of unclear clinical significance.

Reporting and grading of complications after mid-urethral sling surgeries: Could the "Clavien-Dindo Classification" be adopted?

Background:

To construct a modified model for reporting and grading of postoperative complications after the mid-urethral sling (MUS) procedure based on the Clavien-Dindo classification. In addition, complications of three different types of MUS were compared.

Materials and methods:

A PubMed search for postoperative complication after MUS was carried out for the period between January 1990 and July 2018. Reported complications were stratified in a plate form designed in accordance with grades of the Clavien-Dindo classification. Then, the proposed model was applied on reported complications in 160 females who underwent three different procedures of MUS (transvaginal tape [TVT], transobturator tape [TOT], and autologous fascial sling) with a minimum follow-up of 24 months.

Results:

The mean ± SD age at time of surgery was 46 ± 7 years. TVT was carried out in 75 (47%) patients, TOT in 40 (25%), and fascial sling in 45 (28%). The total number of complications was 62 in 43 (26.8%) patients. The vast majority of complications were Grade I and Grade II 19 (12%) and 21 (13%) out of 160 patients, respectively. Transient postoperative voiding difficulty (Grade II) and de novo urgency (Grade II) were the most prevalent complications in the fascial sling method (15.4% for each), whereas transient thigh pain (Grade II) was the most frequently reported complication after TOT (10%). Life-threatening vascular injury (Grade IV-a) was a serious complication in TVT cases.

Conclusions:

Postoperative complications of the MUS could be graded according to Clavien's classification. The vast majority of complications were Graded I or II. TVT can cause serious life-threatening complications.

Mesh Sling Arm Removal for Persistent Pain After an Initial Vaginal Suburethral Mesh Sling Removal Procedure

OBJECTIVES

Pain is a recognized complication of mid-urethral slings (MUS), which may lead to suburethral sling removal (SSR) alone, or to a more extensive removal approach. We report on the outcomes of women who required an SSR or an additional secondary MUS arm removal for pain only.

METHODS

After Institutional Review Board (IRB) approval, the charts of nonneurogenic women who underwent SSR for pain only were reviewed. Demographic information, MUS type, self-reported pain resolution, and preoperative and postoperative questionnaires, including Urogenital Distress Inventory-Short form question 6 (UDI-6 Q6) scores, were collected for the SSR (group 1) and secondary removal (group 2) groups.

RESULTS

Of 52 women who underwent SSR for pain only between 2005 and 2018, 16 (31%) required a secondary procedure to remove the extension arms due to persistent pain after SSR. All women in group 2 experienced pain immediately after SSR (UDI-6 Q6 score of 2 to 3). Patients whose pain improved after SSR presented at a median 61 months after MUS whereas those in group 2 underwent SSR at median 34 months after MUS. Median duration of follow-up in group 2, after the secondary procedure, was 34 months. Over one half of those in group 2 (54%) noticed pain cure/improvement. Seven were left with persistent pain.

CONCLUSIONS

In women who underwent SSR for pain only, 67% reported pain resolution. An additional procedure to remove the extension arms of the mesh was performed in one third of women for persistent pain after SSR.

Stress Urinary Incontinence After Urethral Diverticulum Repair Without Concomitant Anti-Incontinence Procedure

OBJECTIVE

To review the rates of persistent and de novo stress urinary incontinence (SUI) following urethral diverticulum (UD) repairs performed without concomitant SUI surgical procedures.

METHODS

Following IRB approval, charts of women who underwent UD excision by three FPMRS surgeons were reviewed. Data collected from the electronic medical record included demographic information, preoperative symptoms and evaluation (validated questionnaires [UDI-6, QoL]), imaging studies, operative details, post-operative symptoms, and subsequent surgical interventions. Excluded were women with <6 months follow-up or concomitant pubovaginal sling placement. SUI was diagnosed by patient report, and UD was confirmed by preoperative magnetic resonance imaging or voiding cystourethrogram. The primary outcome was defined as the rate of SUI following UD repair. Secondary outcomes included resolution of pre-operative SUI, rate of self-reported secondary SUI, and SUI surgical intervention post-UD repair.

RESULTS

From 2003-2018, 61 of 67 women met study criteria. SUI pre-UD repair was reported in 31 of 61 (51%). During UD repair, 3 patients underwent Martius flap interposition. Post-UD repair, 18/61 (30%) reported SUI. Persistent SUI was present in 14 of 31 (45%), and de novo SUI occurred in 4 of 30 (13%). Postoperative responses revealed statistically significant improvements in QoL and most questions of UDI-6 at median 18 months. SUI was surgically managed in 3 patients using bulking agent injections (2) and autologous fascial sling placement (1). Overall, 3 of 61 (5%) underwent SUI intervention post-UD repair.

CONCLUSION

Without prophylactic SUI corrective procedures performed during UD repair, we observed a low rate of de novo SUI, and only 5% with bothersome SUI opting for surgical intervention.

Urinary incontinence before and after pelvic organ prolapse surgery-A national database study

INTRODUCTION AND HYPOTHESIS

To investigate how pelvic organ prolapse (POP) surgery affects symptoms of urinary incontinence (UI) in women with POP and concomitant UI.

METHODS

Data from the Danish Urogynaecological Database were collected from 2013 to 2016. Inclusion criteria were urinary incontinent women who underwent POP surgery alone. Based on the preoperative results of the International Consultation on Incontinence Questionnaire-Urinary Incontinence-short form (ICIQ-UI-sf), women were categorized with stress urinary incontinence (SUI), urgency urinary incontinence (UUI) or mixed urinary incontinence (MUI). Postoperatively, the women were categorized based on the postoperative ICIQ-UI-sf, except here, undefined urinary incontinence and urinary continence were added to the categories. Statistical analyses included multivariate logistic regression analyses, examining the odds of urinary continence in each category. The included parameters were preoperative POP stage (POP-Q), compartment, BMI, age and preoperative ICIQ-UI-sf total score. P-values < 0.05 were considered statistically significant.

RESULTS

A total of 1657 women were included. Significantly more women with preoperative UUI achieved urinary continence (60%) compared to women with preoperative SUI (52%) and MUI (38%). More than 70% of all women achieved either urinary continence or an improvement in UI, regardless of subtype. For women with UUI, the likelihood of achieving urinary continence was higher if the anterior compartment was involved. Women with MUI were more likely to achieve urinary continence if they had POP-Q stage 3-4.

CONCLUSIONS

Most women with symptomatic POP and concomitant UI find that their UI is either cured or improved after POP surgery alone.

Polypropylene and polyvinylidene fluoride transobturator slings for the treatment of female stress urinary incontinence: 1-Year outcomes from a multicentre randomized trial

AIMS

To compare the effectiveness and safety of polypropylene (PP) and polyvinylidene fluoride (PVDF) transobturator tapes (TOT) for the treatment of female stress urinary incontinence (SUI).

METHODS

This is a multicentre randomized trial. Women with SUI or stress-predominant mixed urinary incontinence and scheduled for a TOT procedure were randomized to PP or PVDF slings. The primary outcome was 1-year cure or improvement rate using composite criteria. Complications were also compared. Relationships with outcomes were analyzed using multivariable logistic regressions models.

RESULTS

From April 2016 to January 2018 285 participants were randomized. PP and PVDF slings showed similar high cure or improvement rate (91.0% vs. 95.6%, p = .138). Improvement in validated questionnaires was also similar. PVDF slings were associated with a lower rate of de novo urgency incontinence (adjusted odds ratio = 0.35; 95% confidence interval = 0.15-0.80). We found no statistical differences in complications rates, although a higher incidence of long-term pain events were observed in the PP group. The study is underpowered to find differences in specific complications owing to the low number of events.

CONCLUSION

PP and PVDF TOTs are equally effective, although PVDF is associated with fewer cases of de novo urgency incontinence. Further studies are needed to give robust conclusions on safety profiles.

Case Report: Management of Multiple Deep-Tissue Cellulitis Without Sling Removal After an Anti-incontinence Procedure in a Female With Diabetes Mellitus

The transobturator suburethral tape procedure is emerging as a preferred surgical option in the management of stress urinary incontinence. This procedure, also called tension-free vaginal tape transobturator (TVT-O) procedure, has fewer risks of injury to the bladder, similar effectiveness, and shorter surgery duration compared with the older tension-free vaginal tape (TVT) procedure. In this study, we report the case of a female patient with type 2 diabetes mellitus who developed emergency ketoacidosis and severe cellulitis after a TVT-O procedure, which was successfully managed without sling removal and open drainage of abscesses after multi-point puncture drainage, guided by ultrasound and appropriate antibiotic administration. The patient showed appropriate urinary continence with controlled diabetes mellitus 24 months after treatment. In conclusion, cellulitis from the pelvic floor to the associated thigh after TVT-O procedure in a diabetic patient can be managed conservatively if no sling exposure is confirmed. However, these patients should be closely observed and followed up during the perioperative period, especially for synthetic sling use.

Single-incision Midurethral Sling by the Dynamic Intraoperative Standing Sling Technique as an Office-based Procedure: A Pilot Study

OBJECTIVES

To assess the safety, feasibility, and short-term success of placing Solyx (Boston Scientific, Marlborough, MA) single-incision midurethral sling (SIMUS) using the Dynamic Intraoperative Standing Sling Technique (DISST) in an office setting under local anesthesia.

METHODS

The safety and efficacy of the in-office Solyx DISST procedure for treatment of stress urinary incontinence was assessed 6 months from the procedure. Improvement in stress urinary incontinence was measured using validated questionnaires (Medical, Epidemiologic, and Social Aspects of Aging, MESA; Incontinence Impact Questionnaire-7, IIQ-7; Pelvic Organ Prolapse/Urinary Incontinence Sexual Function, PISQ-12) and by a negative standing provocative stress test. Postoperative complications were documented along with subjective pain diaries, return to work/activities, and overall satisfaction.

RESULTS

From July 2019 through February 2020, 20 subjects underwent in-office Solyx procedure by the DISST technique. Six of the 20 (30%) subjects required intraoperative sling adjustments. There were no complications as related to the office-based procedure. Participants reported a favorable intraoperative experience. Subjects had excellent postoperative pain control and early return to work and normal activities. At 6 months, all 20 subjects had negative standing provocative stress tests, showed statistically significant improvements on MESA, IIQ-7, and PISQ-12, and reported high satisfaction and acceptance for the procedure and outcomes. There were no late (>6 weeks) complications associated with the Solyx procedure.

CONCLUSIONS

It appears safe and feasible to perform Solyx SIMUS by the DISST method in the office. Subjects remained dry and reported excellent improvement in symptoms and quality of life 6 months from surgery.

Contasure-needleless single incision slings versus transobturator slings (TOT/TVT-O) for female patients with stress urinary incontinence: a systematic review and meta-analysis

Background

To assess the current evidence on the effectiveness and safety of Contasure-Needleless (C-NDL) versus transobturator slings (TOT/TVT-O) in the management of female stress urinary incontinence (SUI).

Methods

A comprehensive literature review of articles that investigated the efficacy and safety of C-NDL and TOT/TVT-O was performed based on studies published before June 2019 and retrieved from PubMed, Embase, CNKI and the Cochrane Library. Two reviewers searched the literature, independently extracted the data and evaluated the quality of the data according to the inclusion and exclusion criteria. A meta-analysis was performed by using Review Manager 5.3 software.

Results

Seven studies with 1188 SUI female patients without intrinsic sphincter deficiency (ISD) or mixed urinary incontinence were included. Our meta-analysis showed that the clinical efficacy of C-NDL is statistically non-inferior to that of TOT / TVT-O in terms of subjective cure rate [OR = 0.77, 95% confidence interval (CI) (0.53 to 1.10), p = 0.15] and objective cure rate [OR = 0.78, 95% CI (0.53 to 1.13), p = 0.19]. In addition, operating times were statistically shorter with C-NDL compared to TOT / TVT-O [mean difference (MD) = − 7.38, 95% CI (− 10.73 to − 4.04), p < 0.0001]. In terms of the postoperative visual analogue scale (VAS) and the incidence of postoperative pain, C-NDL has a greater advantage [MD = − 1.71, 95% CI (− 2.91 to − 0.50), p = 0.005]; [OR = 0.21, 95% CI (0.05 to 0.96), p = 0.04]. Complication rates were statistically similar between the groups, except for groin pain which was higher in TOT / TVT-O.

Conclusion

Our data suggest that C-NDL slings have similar short-term efficacy as TOT/TVT-O in curing SUI patients. Compared with TOT/TVT-O, C-NDL is associated with a shorter operative time, and the incidence of postoperative pain is decreased. Nevertheless, these findings should be further confirmed through large-volume, well-designed prospective randomized controlled trials (RCTs) with long-term follow-up.

Therapeutic effects of Low intensity extracorporeal low energy shock wave therapy (LiESWT) on stress urinary incontinence

This study aimed to evaluate the therapeutic effects of Low intensity extracorporeal low energy shock wave therapy (LiESWT) on stress urinary incontinence (SUI). The investigation was a single-arm, open-label, multicentre study conducted in Taiwan. 50 female patients with SUI received LiESWT-treated with 0.25 mJ/mm² intensity, 3000 pulses, and 3 pulses/second, once weekly for 4-weeks (W4) and 8-weeks (W8). The pad test, uroflowmetry, life quality questionnaires, and 3-day urinary diary measurement were performed before and after LiESWT intervention. The results revealed that 8-week of LiESWT treatment meaningfully improved urine leakage (pad test), maximum flow rate, post-voided residual urine, average urine volume, functional bladder capacity, urinary frequency, urgency symptom, and nocturia, which also persisted to show significant improvements at 1-month follow up (F1). Moreover, bothersome questionnaires scores were significantly improved at W4, W8, and F1 as compared to the baseline (W0). These results indicated that 8 weeks of LiESWT attenuated SUI symptoms on physical activity, reduced bladder leaks and overactive bladder (OAB), implying that LiESWT brought significant improvement in the quality of life. (ClinicalTrials.gov number, NCT04059133).

Three-year follow-up in patients with urinary stress incontinence treated with Altis® single-incision sling

BACKGROUND

The purpose of the study is to report three years follow-up of single incision slings for the treatment of stress urinary incontinence (SUI). The main outcomes are to evaluate the efficacy of the device and to assess safety, adverse events, quality of life, demographic features of treated women and prognostic factors for SUI.

METHODS

We performed a retrospective, double-center, single-arm study. Data were collected by medical records and a telephone interview 3 years after the implant of the mini-sling. Complication rate, subjective efficacy and degree of satisfaction were investigated.

RESULTS

Fifty-four patients were treated between March 2015 and March 2017, of which 47 answered the survey. Forty-one of 47 procedures (87.2%) were considered effective. Among more relevant complications, there was one case of extrusion of mesh and three cases of new onset of urinary disfunction, of which two cases of urgency urinary incontinence (UUI) and one case of de-novo SUI. Most complications were solved within few days after the procedure. Concerning the subjective impression of improvement, investigated by using the Patient Global Impression of Improvement (PGI-I) questionnaires, 41 patients reported subjective satisfaction, three reported no change in quality of life and three patients had worsening of symptoms.

CONCLUSIONS

The procedure was safe and effective for the treatment of SUI but more data are needed to confirm our preliminary results.

The new etiology and surgical therapy of stress urinary incontinence in women

OBJECTIVES

To determine the subjective and objective cure rate of a urethral stabilization procedure (USP) for stress urinary incontinence (SUI) in women; to describe this new surgical intervention; to record its potential complications; to establish the SUI etiology.

STUDY DESIGN

The author conducted a prospective case series study in ambulatory settings and under local anesthesia. Thirty-four consecutive women with uncomplicated SUI subjected to USP, which was performed by reconstructing site-specific defects within the urethral stabilizing mechanism (USM) and using no surgical slings, meshes or absorbable sutures. The paravaginal defect(s) was repaired by transvaginal approach. The endopelvic fascia was sharply separated from the ventral perineal membrane (VPM) just above the anterior urethral meatus. The vestibular bulbs sharply dissected from VPM and advance upwards. The VPM defect(s) reconstructed and vestibular bulbs placed back to the original location. The access to the peri- and the para-urethral region was created by making a lateral vertical incision, aside from the lateral urethral meatus and defects were repaired. The suburethral transverse incision was made beneath the urethral meatus and the stratum-by-stratum surgical dissection conducted until the lateral vaginourethral ligament is visualized bilaterally. The defect(s) within the vaginourethral ligaments was surgically reconstructed, and the vaginal wall repaired. The primary outcome measured subjective and objective cure rates, and the secondary outcome measured the occurrence of potential complications. The five-year postoperative follow-up was conducted.

RESULTS

Two out of thirty-four patients dropped-out from the study. The USP performed without difficulties, and no severe complication observed. One-subject developed superficial wound separation (3.1 %) and one-subject (3.1 %) developed urinary urge incontinence at the 5-postoperative-year. At 60-month follow-up subjective and objective cure rates were a 92 % and an 88 % respectively.

CONCLUSIONS

The urethral stabilization procedure yields a high degree of subjective and objective cure rates without severe complications and is a well-tolerated operation by women. The urethral stabilization procedure is a simple, easy to implement, and reproducible method for uncomplicated stress urinary incontinence in women. Site-specific defects within the urethral stabilizing mechanism constitute the etiology of the stress urinary incontinence in women.

Single-incision midurethral sling shows less pain and similar success rate in a short-term follow-up compared to the transobturator tape method in the treatment of stress urinary incontinence

OBJECTIVE

To compare the efficacy, complications, quality of life, and patient satisfaction rates in women treated for stress urinary incontinence (SUI) using the adjustable anchored single-incision midurethral sling (SIMS) and standard midurethral sling (MUS) procedures.

MATERIAL AND METHODS

A total of 113 women between October 2012 and October 2016 underwent either the adjustable SIMS (n=54) or MUS (n=57) procedure. The postoperative pain profile was assessed using a 10-point visual analog scale at the fixed time-point quality of life and an additional postoperative 3^rd week appointment. We asked our patients the following two questions to evaluate their satisfaction with surgery and their preference: "Would you have this kind of surgery again?" (Q1), and "Would you recommend this type of surgery to another patient with same symptoms?" (Q2). For the evaluation of patient complaints, the Incontinence Impact Questionnaire (IIQ-7) and Urinary Distress Inventory (UDI-6) were used before and after the procedure.

RESULTS

Women in the SIMS group had a significantly lower postoperative pain profile for up to 3 weeks (p<0.001). There was no significant difference in perioperative complications and postoperative continence rates between the groups. With regard to Q1 and Q2, a significant difference was found between the groups (p=0.003 and p=0.002, respectively). While the questionnaire scores of the IIQ-7 and UDI-6 were also significantly improved at postoperative evaluations (p<0.001), there was no significant difference between the two groups.

CONCLUSION

SIMS is associated with a significantly improved postoperative pain profile and earlier return to work when compared to MUS.

Multiple doses of stem cells maintain urethral function in a model of neuromuscular injury resulting in stress urinary incontinence

Stress urinary incontinence (SUI) is more prevalent among women who deliver vaginally than women who have had a cesarean section, suggesting that tissue repair after vaginal delivery is insufficient. A single dose of mesenchymal stem cells (MSCs) has been shown to partially restore urethral function in a model of SUI. The aim of the present study was to determine if increasing the number of doses of MSCs improves urethral and pudendal nerve function and anatomy. We hypothesized that increasing the number of MSC doses would accelerate recovery from SUI compared with vehicle treatment. Rats underwent pudendal nerve crush and vaginal distension or a sham injury and were treated intravenously with vehicle or one, two, or three doses of 2 × 10⁶ MSCs at 1 h, 7 days, and 14 days after injury. Urethral leak point pressure testing with simultaneous external urethral sphincter electromyography and pudendal nerve electroneurography were performed 21 days after injury, and the urethrovaginal complex and pudendal nerve were harvested for semiquantitative morphometry of the external urethral sphincter, urethral elastin, and pudendal nerve. Two and three doses of MSCs significantly improved peak pressure; however, a single dose of MSCs did not. Single, as well as repeated, MSC doses improved urethral integrity by restoring urethral connective tissue composition and neuromuscular structures. MSC treatment improved elastogenesis, prevented disruption of the external urethral sphincter, and enhanced pudendal nerve morphology. These results suggest that MSC therapy for postpartum incontinence and SUI can be enhanced with multiple doses.

Management of vaginal mesh exposure: A systematic review

Objectives: To identify various predisposing factors, the clinical presentation, and the management of vaginal mesh-related complications, with special emphasis on mesh exposure and the indications for and results of vaginal mesh removal.

Methods: A systematic literature review was performed using a search strategy based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. PubMed was queried for studies regarding aetiology, risk factors, and management of vaginal mesh exposure from 1 January 2008 to June 2018. Full-text articles were obtained for eligible abstracts. Relevant articles were included, and the cited references were used to identify relevant articles not previously included.

Results: A total of 102 abstracts were identified from the PubMed search criteria. An additional 45 studies were identified based on review of the cited references. After applying eligibility criteria and excluding impertinent articles, 58 studies were included in the final analysis.

Conclusion: Numerous studies have found at least some degree of symptomatic improvement regardless of the amount of mesh removed. Focal areas of exposure or pain can be successfully managed with partial mesh removal with low rates of complications. With partial mesh removal, many patients will ultimately require subsequent mesh removal procedures. For this reason, complete mesh excision is an alternative for patients with diffuse vaginal pain, large mesh exposure, and extrusion of mesh into adjacent viscera. However, when considering complete mesh removal, it is important to counsel patients regarding possible complications of removal and the increased risk of recurrent stress urinary incontinence and pelvic organ prolapse postoperatively.

Transobturator tape material detected in the bladder neck: a case report

INTRODUCTION

Stress urinary incontinence surgeries (transobturator tape and tension-free vaginal tape) are safely performed with success rates over 90%. The transobturator tape procedure attracted more attention due to the lack of major complications, such as intraabdominal organ and vascular injuries, related to the tension-free vaginal tape procedure. Although there are no major or mortality-related complications, more lower urinary complaints, especially vaginal erosion, are reported in transobturator tape surgery. Here we present a rare complication of transobturator tape surgery: the accidental placement of mesh material in the bladder neck. With this case report, we aimed to discuss the diagnosis and management of misplaced transobturator tape material.

CASE PRESENTATION

A 38-year-old Caucasian woman who had stress urinary incontinence that had persisted for 6 years underwent transobturator tape surgery in a different clinic 2 years ago. Subsequently, she presented to our clinic with lower urinary tract complaints such as incontinence and dysuria. A physical examination was unremarkable besides total incontinence. A diagnostic cystoscopy was performed and sling material that crossed her bladder neck from 3 o'clock to 10 o'clock was identified. The misplaced transobturator tape material was cut endoscopically with an internal urethrotomy knife. Afterwards, a midurethral incision was made and mesh parts were removed bilaterally. After successful removal of the mesh material, a new transobturator tape was placed.

CONCLUSIONS

Even though transobturator tape surgery is a safe and effective procedure for stress urinary incontinence, certain complications can be encountered. Misplacement of the mesh material through the bladder neck is a rare complication and can be managed by successfully removing the mesh material and appropriately placing new transobturator tape material.

Exploring stress urinary incontinence outcomes after sling excision for perforation or exposure

OBJECTIVE

This study assessed stress urinary incontinence (SUI) outcomes after sling excision for urinary tract perforation or vaginal exposure, and compared the outcomes of concomitant versus staged autologous fascia pubovaginal sling (AFPVS).

METHODS

A retrospective chart review of all patients who underwent midurethral sling (MUS) excision for urinary tract perforation or vaginal exposure at a tertiary referral center between 2010 and 2015 was performed. Therapeutic strategies were categorized as concomitant AFPVS, staged AFPVS, and no anti-incontinence procedure.

RESULTS

In all, 32 patients were included for analysis: 13 with vaginal tape exposure (40.6%) and 19 with urinary tract tape exposure (59.4%). In patients who had SUI prior to sling excision (43.8%), the rate of resolved or improved SUI postoperatively was higher in the concomitant AFPVS group than in those who underwent sling excision alone (83.3% vs 12.5%, respectively; P = 0.03). Of 18 patients with no SUI prior to sling excision, 12 experienced recurrent SUI after sling removal (66.7%). The rate of recurrent SUI was lower in patients with vaginal MUS exposure than urinary tract MUS perforation, but this did not reach statistical significance (57.1% vs 72.7%, respectively; P = 0.63). The rates of resolved SUI after AFPVS were comparable in patients with concomitant and staged AFPVS (66.7% vs 71.4%, respectively; P = 0.99).

CONCLUSIONS

Many patients with MUS perforations or exposures will have SUI at initial presentation or develop SUI after removal of the synthetic sling. The decision to perform a concomitant AFPVS or to stage the surgical management of SUI can be individualized.

Long-term outcomes and quality of life effects of single incision mini sling procedure in stress urinary incontinence patients

OBJECTIVE

We aimed to evaluate the long-term outcomes and quality of life of patients who underwent single incision minisling (SIMS) procedure.

STUDY DESIGN

62 patients who were diagnosed with stress urinary incontinence (SUI) and received treatment with SIMS procedure (Ophira, Promedon, Argentina) were included in the study. Mean age was 50.73 ± 9.28 years and mean follow-up duration after surgery was 30.68 ± 7.52 months. Preoperative urological and gynecological features of the patients were recorded. Gynecological examination, pelvic ultrasonography, stress test, Q-tip test, cystometry were performed and incontinence and quality of life questionnaires (ICIQ-SF, IIQ-7, UDI-6, VAS-QOL, FSFI) were completed by all patients before and after the operation.

RESULTS

Stress urinary incontinence was observed in all patients during pre-op evaluations. 62 patients aged between 35-85 (mean age 50.73 ± 9.28) years were included and follow up duration ranged between 12-44 (average 30.68 ± 7.52) months. In regard to patient evaluations, 27 patients (43.5%) felt that the surgery was very effective, 25 (40.3%) felt surgery was effective and 10 (16.1%) did not report any difference after surgery. In the long-term postoperative follow up; 2 (3.2%) patients had dyspareunia and 7 (11.3%) patients had vaginal tape erosions which were diagnosed 2-40 months postoperatively. According to Q-tip test results, proximal urethral mobility was significantly decreased after surgery. All questionnaire scores were also significantly improved at post-operative evaluations. (P < 0.001) CONCLUSIONS: Our study confirmed that the Ophira mini sling technique provided high subjective cure rate and improved symptoms and quality of life in patients with SUI. These results suggest that the single incision mini sling procedure is an advisable alternative to other surgical procedures due to its low complication rates and ease of learning and applying the procedure. This procedure also demonstrated excellent tolerability, minimal pain, low morbidity and increased quality of life scores, in ICIQ-SF, IIQ-7, UDI-6, VAS-QOL, FSFI.

Intraoperative Vaginal Perforation During Various Mid-Urethral Sling Procedures Treating Female Stress Urinary Incontinence

BACKGROUND

Incidence of intraoperative vaginal perforation is generally considered to be low but varies among different procedures. Vaginal perforation could not only prolong the surgeries and aggravate surgical trauma but also result in postoperative discomfort or even a second surgery.

METHOD

Vaginal perforation, vaginal epithelial perforation, vaginal wall perforation, vaginal penetration, urinary incontinence were searched in PubMed, Cochrane, Embase database to identify the qualified clinical trial and relevant literature sources were also searched.

RESULTS

A total of 9223 cases of from 33 trials from literatures and 387 cases from our own trail were analyzed, which provided detailed data on intraoperative vaginal perforation. Incidence of intraoperative vaginal perforation during mid-urethral sling surgery treating stress urinary incontinence was generally low, which was 1.56%. Incidence of intraoperative vaginal perforation during transobturator (TOR) procedure was higher than that during retropubic (RPR) procedure, which were 2.11% and 0.89% respectively. Incidence of intraoperative vaginal perforation during outside-to-inside TOR procedure like TOT and MONARC was higher than that during inside-to-outside TOR procedure like TVT-O, which were 2.74% and 1.52%, respectively. Incidence of intraoperative vaginal perforation during single-incision surgery like H-type TVT-SECUR reached 1.97%, while no report on U-type TVT-SECUR surgeries.

CONCLUSION

The incidence of intraoperative vaginal during mid-urethral sling procedures for female stress urinary incontinence is fairly high. Vaginal perforation was more common in trans-obturator route (TOR) than retropubic route (RPR). In TOR route, it was less frequent in inside-to-outside procedure than outside-to-inside procedure. Surgery proficiency could also have an impact on this complication.

Results of the British Association of Urological Surgeons female stress urinary incontinence procedures outcomes audit 2014-2017

OBJECTIVES

To analyse the results of the stress urinary incontinence (SUI) audit conducted by the British Association of Urological Surgeons (BAUS), and to present UK urologists' contemporary management of SUI.

PATIENTS AND METHODS

The BAUS audit tool is an online resource, to which all UK urologists performing procedures for SUI are invited to submit data. The data entries for procedures performed during 2014-2016 were collated and analysed.

RESULTS

Over the 3-year period analysed, 2917 procedures were reported by 109 surgeons, with a median of 20 procedures reported per surgeon. A total of 2 366 procedures (81.1%) were recorded as a primary surgery, with 548 procedures (18.8%) performed for recurrent SUI. Within the time period analysed, changes were noted in the frequency of all procedures performed, with a trend towards a reduction in the use of synthetic mid-urethral tapes, and a commensurate increase in the use of urethral bulking agents and autologous fascial slings. A total of 107 (3.9% of patients) peri-operative complications were recorded, with no association identified with patient age, BMI or surgeon volume. Follow-up data were available on 1832 patients (62.8%) at a median of 100 days postoperatively. Reduced pad use was reported in 1311 of patients (84.5%) with follow-up data available and 86.3% reported a pad use of one or less per day. In all, 375 patients (85%) reported being satisfied or very satisfied with the outcome of their procedure at follow-up, although data entry for this domain was poor. De novo overactive bladder (OAB) symptoms were reported by 15.2% of patients (263/1727), and this was the most commonly reported postoperative complication. For those reporting pre-existing OAB prior to their SUI surgery, 28.7% (307/1069) of patients reported they got better after their procedure, whilst 61.9% (662/1069) of patients reported no change and 9.4% of patients (100/1 069) got worse.

CONCLUSIONS

This review identified that, despite urological surgeons undertaking a relatively low volume of procedures per year, SUI surgery by UK urologists is associated with excellent short-term surgeon- and patient-reported outcomes and low numbers of low grade complications. Complications do not appear to be associated with surgeon volume, nor do they appear higher in those undergoing mesh surgery. Shortfalls in data collection have been identified, and a longer follow-up period is required to comment adequately on long-term complications, such as chronic pain and tape extrusion/erosion rates.

Retrospective review of intra- and post-operative complications with minimal versus large space of Retzius infiltration at the time of retropubic TVT placement

INTRODUCTION AND HYPOTHESIS

A concern when using the retropubic tension-free vaginal tape (TVT) for stress urinary incontinence (SUI) is bladder perforation. This article describes a technique hypothesised to reduce the risk of intra-operative bladder perforation, termed the large space of Retzius infiltration (LSORI) technique. A large volume of infiltration of 360 ml saline-vasoconstrictor solution (180 ml × 2) into the space of Retzius (LSORI) at the time of retropubic TVT insertion will reduce the incidence of intra-operative bladder perforations.

METHODS

This was a retrospective study reviewing the medical records of 89 women who underwent the retropubic TVT procedure at two urogynaecology Units. The intra- and post-operative characteristics associated with minimal (MSORI) versus large retropubic space of Retzius infiltrations (LSORI) were examined.

RESULTS

Eighty-nine patients undergoing SUI surgery met the inclusion criteria. Forty-one patients had MSORI (volume range 20-60 ml bilaterally) versus 48 who had the 180-ml bilateral LSORI. No bladder perforations (0%) occurred in the LSORI group versus four in the MSORI group (9.8%), found to be statistically significant (p = 0.013). All other outcomes examined had no statistical difference. The TVT-related pain incidence: 8.3% (LSORI) versus 9.8% (MSORI). Post-operative urinary retention incidence was 6.3% (LSORI) and 14.6% (MSORI). Retropubic haematoma incidence was 0% (LSORI) and 2.4% (MSORI). Post-operative UTI rate was 12.5% (LSORI) and 17.1% (MSORI).

CONCLUSIONS

This retrospective review revealed the potentially beneficial effect of the large (180 ml × 2) bilateral SORI with retropubic TVT placement in terms of the reduction in risk of bladder perforation. It also showed no potential added risk of post-operative complications.

Comparative study of transobturator sling with and without concomitant prolapse surgery for female urodynamic stress incontinence

AIM

To demonstrate the clinical and urodynamic outcomes of transobturator sling (TOT) with or without concomitant prolapse surgery for the treatment of urodynamic stress incontinence (USI).

METHODS

We recruited 143 consecutive patients diagnosed with USI, who received outside-in TOT in a university hospital. Preoperative and postoperative examinations were implemented using structured urogynecological questionnaires, pelvic organ prolapse quantification examination and urodynamic testing. Patient demographics, surgical and urodynamic results were compared between TOT with and without concomitant prolapse surgery.

RESULTS

The mean follow-up was 30.1 months (range 12-57). Postoperative stress urinary incontinence (SUI) occurred in 10 (7%) patients at 3 months and 10 (7%) patients at 12 months postoperatively. There was no significant difference in prevalence of postoperative SUI between groups of TOT only and TOT combined with pelvic surgery. Preoperative urodynamic results demonstrated that TOT only (n = 96) had a higher maximal flow rate and a lower residual urine amount when compared to TOT combined with pelvic surgery (n = 47). A significant decrease in maximal urethral closure pressure (MUCP) was found in 119 patients who received postoperative urodynamic examination. In comparison with preoperative urodynamic data, postoperative urodynamic results showed a significant decrease in MUCP in the TOT combined with prolapse surgery group, but no significant urodynamic changes in the group of TOT only.

CONCLUSION

Both TOT and TOT combined with prolapse surgery can be effective in correcting SUI in patients with USI 12 months postoperatively, with significant changes in MUCP.

The efficacy and safety comparison of surgical treatments for stress urinary incontinence: A network meta-analysis

AIMS

Stress urinary incontinence (SUI) is a common problem worldwide. Mainstream surgical procedures include tension-free vaginal tape (TVT), transobturator tape (TOT), tension-free vaginal tape-obturator (TVT-O), tension-free vaginal tape SECUR (TVT-S), and adjustable single-incision sling (Ajust). The aim of this study was to compare the efficacy and safety of these surgical procedures and assess which surgery is most optimal for SUI by adopting a network meta-analysis (NMA).

METHODS

Electronic databases including PubMed, Cochrance Library, and Embase database were researched systematically, until March 21, 2017. The randomized controlled trials (RCTs) that compared the efficacy and safety of TVT, TOT, TVT-O, TVT-S, and Ajust were identified. The studies were included in the analysis when met the predefined inclusion criteria. After demographic and outcome data extraction, a network meta-analysis was conducted with software R 3.3.2 and STATA 14.0. Objective cure rate, subjective cure rate, postoperative complication rate, bladder perforation, tape erosion, urinary retention, and postoperative pain were considered as outcomes, and the outcomes were displayed as odds ratios (ORs) and 95% credible intervals (CrI). The consistency of direct and indirect evidence was assessed by node splitting. The ranks based on probabilities of intervention for the different endpoints were performed.

RESULTS

Fourty-five RCTs with 7295 participants were analyzed. The NMA results revealed that, TVT, TOT, and Ajust had a higher objective cure rate than TVT-O and TVT-S (TVT-O: OR = 0.76, 95%CI [0.61, 0.94]; TVT-S: OR = 0.41, 95%CI [0.28, 0.60]). TVT, TOT, and TVT-O had a superior subjective cure rate than TVT-S and Ajust (Ajust: OR = 0.45, 95%CI [0.20, 0.91]; TVT-S: OR = 0.29, 95%CI [0.15, 0.56]). With TVT as the reference, TVT-S had a statistically lower postoperative complication rate (TVT-S: OR = 0.39, 95%CI [0.16, 0.89]). TVT-O, TVT-S, and TOT had a significantly lower bladder perforation rate (TOT: OR = 0.076, 95%CI [0.0060, 0.37]; TVT-O: OR = 4.1e-17, 95%CI [6.1e-48, 0.0032]; TVT-S: OR = 3.8e-17, 95%CI [1.8e-48, 0.0052]). There were no obvious differences between the five treatments for tape erosion. TVT-O exhibited a less postoperative retention (TVT-O: OR = 0.35, 95%CI [0.16, 0.74]). Probabilities of ranking results indicated that TOT was the treatment with best ranking in efficacy and a relatively high safety.

CONCLUSIONS

Our study recommend TOT as the optimal regimen for SUI with high efficacy and moderate safety when compared with TVT, TVT-O, TVT-S, and Ajust interventions. However, with the limitation of our study, additional high-quality studies are needed to further evaluate the outcomes.
