Long-term follow-up of a multicentre randomised controlled trial comparing tension-free vaginal tape, xenograft and autologous fascial slings for the treatment of stress urinary incontinence in women

Application of human breast acellular dermal matrix (hbADM) in sling surgery for female stress urinary incontinence: a phase 1 clinical trial

PURPOSE

To evaluate the safety and feasibility of human breast acellular dermal matrix (hbADM) as an alternative to synthetic mesh and autologous fascia in sling surgery for female stress urinary incontinence (SUI), and to assess its preliminary efficacy in a phase 1 clinical trial.

METHODS

Twenty-five women with pure SUI underwent hbADM sling surgery at two centers. The primary outcomes were safety (adverse events) and feasibility. Secondary outcomes included changes in International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) scores, Patient Global Impression of Improvement (PGI-I), cough stress test results, and uroflowmetry parameters. Patients were followed up for 3 years. Statistical analysis included descriptive statistics, paired t-tests, and Wilcoxon signed-rank tests.

RESULTS

The hbADM sling procedure was performed as planned in all patients. Adverse events occurred in 10 patients (40%). Intraoperative and early postoperative events (9/25, 36%) were mild and consistent with standard sling procedures. Late complications, observed in 2 patients (8%), were limited to recurrent urinary tract infections (UTIs); one of these patients had also presented a UTI in the early phase. No cases of sling erosion or chronic pain were observed. Objective cure rates (negative cough stress test) remained high at 100% at 1 year and 95% at 3 years. However, patient-reported success (PGI-I ≤ 2) declined from 92% at 1 month to 65% at 3 years. The mean ICIQ-SF score improved significantly from 15.3 ± 3.4 at baseline to 5.8 ± 2.4 at 3 years post-surgery (p < 0.001). Uroflowmetry parameters remained stable throughout the follow-up. The recurrence rate was 10% at 3 years.

CONCLUSION

This phase 1 trial demonstrates the safety and feasibility of hbADM slings for female SUI treatment, with promising efficacy outcomes up to 3 years post-surgery. These results support further investigation of hbADM sling in larger, randomized controlled trials.

Comparison of midurethral tape with autologous rectus fascial sling surgery for stress urinary incontinence: A systematic review and meta-analysis

Objectives

To compare the success rates of autologous fascial mesh (sling and transobturator tape [TOT]) with midurethral synthetic meshes (tension-free vaginal tape sling [TVT] and TOT) for stress urinary incontinence.

Materials and methods

A literature search for studies published in English was conducted from May 10, 2022, to June 1, 2022. The search included MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Google Scholar, and ProQuest, using the terms{"Autologous fascial slings"}OR {"AFS"} AND{"TOT"} OR {"Transobturator tape"} OR{"TVT"} OR{"Transvaginal tape"}. A total of 20 studies, including 10 randomized controlled trials, were selected for the review. RevMan software (version 5.3) was used to calculate the pooled effect estimates for operative and postoperative variables.

Results

In the systemic review, 20 studies, including 10 randomized controlled trials, were assessed. In the TVT versus autologous pubovaginal sling (A-PVS) groups, the effect estimates for the surgical duration, catheter duration, success, and complication rates were more advantageous for TVT. However, in comparison to autologous transobturator tape groups, TOT provided better operative time and a shorter hospital stay. Moreover, in comparison to the A-PVS group, the TOT group was superior in terms of operating time, urethral catheterization, hospital stay, amount of residual urine, and wound complications. The A-PVS group had significantly more groin and thigh pain.

Conclusions

During medium- and long-term follow-ups, the use of autologous rectus fascia grafts using a A-PVS or TOT provided similar complication rates and urinary continence results as using midurethral synthetic meshes (TVT and TOT).

Comparison of Surgical Outcomes of Autologous Mid-Urethral Fascia Slings and Retropubic Mid-Urethral Slings for Women Undergoing a Primary Surgery for Stress Urinary Incontinence: A Systematic Review and Meta-Analysis

AIM

Current guidelines on surgical treatment of stress urinary incontinence (SUI) recommend an informed decision making process between the physicians and patients reviewing all available surgical options with and without mesh. However, there is a lack of synthesized clinical evidence on some of the comparisons that can feed into patient counseling processes. The aim of this study was to review the available studies comparing clinical outcomes of an autologous fascial sling (AFS) and a retropubic (RP) synthetic sling for women undergoing a primary surgery for SUI.

METHODS

We conducted a literature search from 1990 to 2024 following international guidelines. We have included studies reporting on comparative outcomes of AFS and RP synthetic sling surgeries as a primary procedure.

RESULTS

Three randomized studies were included with follow-up durations ranging from 24 months to 10 years. The mean percentage change in symptom scores ranged from 27.7% to 44.9%, with no significant difference between the two sling types. There was no difference between groups with regard to objective cure rates, subjective cure rates and length of hospital stay between AFS and RP slings. AFS surgeries had longer operative times. There were concerns about bias, particularly related to allocation, blinding, and missing outcome data.

CONCLUSION

Overall, both types of slings had similar cure rates but AFSs were associated with longer operative times. The study highlights the need for more research on the comparative effectiveness of AFS and synthetic slings for SUI surgery to guide decision-making for SUI surgical treatments.

Perspectives on technology: urethral slings in a post-mesh world

OBJECTIVES

To detail the history of synthetic mid-urethral slings (SMUSs) and fascial slings, their efficacy, associated complications, and changes to practice that have occurred after the issuing of the 2011 US Food and Drug Administration (FDA) Safety Communication statement on transvaginal mesh (TVM), and to highlight the need for surgical registries and high-quality randomised controlled data to guide recommendations for continence procedures, in view of current concerns regarding mesh.

METHODS

A literature search was conducted in EMBASE, PubMed, and the Cochrane Database of systematic reviews to identify articles published from 2011 onward, following the FDA Safety Communication regarding TVM.

RESULTS

Prior to the formal FDA Safety Communication in 2011, TVM was considered a safe option for the treatment of both pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The 2011 FDA safety communications and ensuing widely publicised litigation against TVM manufacturers have shifted both surgeon and patient acceptance of mesh products. Several efforts by medical and government bodies have been made to establish ways to monitor the surgical outcomes and safety of mesh products. The Australasian Pelvic Floor Procedure Registry is one such example. Although SMUSs have a long and established safety profile, perceptions of mesh products for SUI have also been negatively affected. The extent of this, however, has yet to be adequately measured through qualitative and quantitative data. The available data suggest it has been difficult for patients and consumers to distinguish between TVM morbidity for POP vs SUI. Furthermore, there remains a lack of high-quality randomised or real-world registry data to definitively exclude the SMUS from the SUI treatment algorithm. Since SMUSs are a viable option for SUI treatment, the concept of a 'post-mesh world' remains contentious.

CONCLUSION

Controversies surrounding SMUSs have changed the treatment landscape of SUI. Against the background of significant litigious action following the FDA warnings against mesh use, there has been significant reduction in the uptake of synthetic mesh products. Although there are ample data related to surgical outcomes and safety for both autologous fascial and retropubic SMUSs in carefully selected patients, informed consent and surgical training will be of paramount importance as newer synthetic materials reach clinical maturity.

Synthetic vs nonsynthetic slings for female stress and mixed urinary incontinence: a systematic review and meta-analysis

OBJECTIVE

This study aimed to systematically review objective and subjective success and surgical outcomes of suburethral sling surgery for female patients with stress or mixed urinary incontinence using synthetic vs nonsynthetic material with corresponding surgical approaches (retropubic or transobturator).

DATA SOURCES

We systematically searched Medline, Embase, EBM Reviews, ClinicalTrials.gov, and Web of Science Core Collection using standardized Medical Subject Headings (MeSH) without date restrictions (PROSPERO-registered). We double-screened studies and used backward citation chaining.

STUDY ELIGIBILITY CRITERIA

We included peer-reviewed randomized controlled trials and prospective or retrospective comparative studies examining outcomes of retropubic or transobturator synthetic vs nonsynthetic (autologous, allograft, or xenograft) slings for female stress or mixed urinary incontinence, with available English or French full texts. We excluded minislings (single insertion point). We allowed slings for recurrent stress or mixed urinary incontinence, and slings concomitant with prolapse surgery, with at least 6 weeks of postoperative follow-up. We excluded systematic reviews, meta-analyses, review studies, case-control studies, case reports, studies that did not describe surgical approach or material, and studies of combination slings.

METHODS

We evaluated study quality using RoB, the Cochrane risk-of-bias tool for randomized controlled trials, and the Newcastle-Ottawa scale for observational studies. We used pooled relative risk with 95% confidence intervals to estimate the effect of sling material type on each outcome through meta-analysis and meta-regression, as appropriate.

RESULTS

We screened 4341 abstracts, assessed 104 full texts, and retained 35 articles (30 separate studies). For retropubic synthetic vs nonsynthetic slings, there was no difference in the number of objectively or subjectively continent patients. The rates of reoperation for stress urinary incontinence and overall were higher with nonautologous retropubic slings than with synthetic slings. Compared with autologous slings, retropubic synthetic slings were associated with higher subjective continence in populations with ≥25% recurrent stress urinary incontinence (relative risk, 1.27; 95% confidence interval, 1.12-1.43). There were no differences in continence between transobturator synthetic and nonsynthetic slings. Subjective satisfaction was better in the transobturator synthetic group than in the autologous sling group (relative risk, 1.42; 95% confidence interval, 1.03-1.94).

CONCLUSION

Synthetic and nonsynthetic slings have comparable objective and subjective success, with synthetic materials generally showing better operative outcomes and fewer complications.

Complications of Synthetic Midurethral Slings: Is There a Relevant Discrepancy Between Observational Data and Clinical Trials?

CONTEXT

The complications of synthetic midurethral slings (MUSs) in women with stress urinary incontinence (SUI) have become a globally debated issue.

OBJECTIVE

To systematically review the short- and long-term complications of mesh slings reported in observational data compared with clinical trial data, to determine whether the complication rates from clinical trials reflects "real-world" observational data.

EVIDENCE ACQUISITION

PubMed and Cochrane Library were searched. Methods as detailed in Preferred Reporting Items for Systematic Reviews and Meta-analyses and Cochrane Handbook for Systematic Reviews of Interventions were followed.

EVIDENCE SYNTHESIS

Thirty registries/databases including 709 335 MUS procedures (1-22 yr of follow-up) were identified. MUS procedures were associated with intraoperative bladder perforation in 0.86-3.6%, urethral perforation in 0-0.1%, vascular injury in 0.04-0.1%, voiding lower urinary tract symptoms (LUTS) in 1.47-3.5%, vaginal exposure in 0.2-1.9%, and reoperation in up to 9% of cases. Forty-three randomised clinical trials were identified, including 6284 women who underwent MUS procedures and 2177 women who underwent other interventions (1-10 yr of follow-up). MUS procedures were associated with urinary tract perforation in 2.58%, vaginal injury in 1.43%, de novo voiding LUTS in 4.37%, de novo storage LUTS in 5.41%, mesh extrusion/exposure (vaginal/urinary tract) in 2.54%, dyspareunia in 2.26%, pain (pelvic/suprapubic/perineal) in 2.83%, and reoperation for complications required in 1.82% of cases. Meta-analyses of the randomised controlled trials revealed that retropubic MUSs were associated with more events of urinary tract perforation (risk ratio [RR] 9.81, 95% confidence interval [CI] 5.05-19.04, high certainty of evidence [COE]) and voiding LUTS (RR 1.57, 95% CI 1.19-2.07, high COE) than transobturator MUSs. MUSs were associated with more events of pain than mini-slings (RR 1.72, 95% CI 1.04-2.87, moderate COE).

CONCLUSIONS

Short- and long-term data on complications of polypropylene mesh used for female SUI are fairly comparable when using outcome data from well-designed clinical trials or from less structured prospective or retrospective registries. Comparisons have to be made with caution since the two systems of data collection are inherently incomparable. This knowledge should be incorporated in the discussion on how to implement polypropylene mesh for female stress incontinence.

PATIENT SUMMARY

In order to know whether mesh tapes used for treating stress incontinence work well and are safe, high-quality information is important. It appears that well-designed clinical studies give similar results to large registration databases. These data should be interpreted with caution in view of the different ways the information was collected. These results will help physicians and patients understand the risks of mesh tapes.

No mess with mesh; vaginal natural orifice transluminal endoscopic surgery (vNOTES) autologous posterior rectus fascia mesh for vaginal urinary incontinence procedures

Urinary incontinence affects 25-45 % of women with the gold standard surgical approach being placement of mid-urethral synthetic slings; tension-free vaginal tape (TVT) and trans-obturator tape (TOT). Due to the controversies regarding vaginal mesh the last decade, an increasing demand has evolved for incontinence treatment without vaginal synthetic mesh. The short term results of autologous rectus fascia sling for TOT surgery have shown similar success rates compared to those after the use of synthetic mesh, but the harvesting of the mesh is less minimally invasive and is associated with longer surgical time. vNOTES is a combination of a vaginal entrance to the abdomen and endoscopy via the vagina. The aim with the video is to show a new surgical technique with a fully vaginal, scarless vNOTES approach for harvesting the posterior rectus fascia for TVT and TOT procedures.

Autologous Slings in Female Stress Urinary Incontinence Treatment: Systematic Review and Meta-Analysis of Randomized Controlled Trials

INTRODUCTION AND HYPOTHESIS

The aim of this study is to evaluate the efficacy and safety of autologous fascial slings (AFS) compared with other surgical methods for female stress urinary incontinence (SUI) treatment.

METHODS

The search was performed on studies published before September 2023 to identify articles assessing the effectiveness and safety of AFS compared with other surgical methods in female SUI. Inclusion criteria were randomized controlled trials (RCTs) and adult women with SUI. Exclusion criteria were other urinary incontinence types, combined pharmacological treatment, pregnancy, and lactation. This systematic review was conducted according to the Population, Intervention, Comparison, and Outcome framework, Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 checklist, and was registered in the Prospective Register of Systematic Reviews.

RESULTS

Twenty RCTs were included in the systematic review and 10 RCTs in the meta-analysis. Comparison between AFS and synthetic midurethral slings (SMUS) did not show any statistically significant differences in the cure rate, frequency of urinary retention, or self-catheterization. SMUS showed more long-term postoperative complications (RR = 0.12, 95% CI: 0.03 to 0.50, p = 0.004), AFS had more in de novo urgency cases: (RR = 2.84, 95% CI: 1.13 to 7.10, p = 0.03). Operation time of SMUS was lower: (RR = 2.87, 95% CI: 2.56 to 3.19, p < 0.00001, I2 = 97%). SMUS showed significantly lower hospital stay duration: (RR = 1.92, 95% CI: 1.44 to 2.41, p < 0.00001).

CONCLUSIONS

In this systematic review and meta-analysis, autologous slings demonstrated the same efficacy in comparison with SMUS in the management of SUI in women. AFS showed lower incidence of long-term postoperative complications. SMUS demonstrated lower operation time, hospital stay and de novo urgency.

Autologous Fascial Slings for Stress Urinary Incontinence: a 17-year Follow-up of a Randomised Controlled Study

INTRODUCTION AND HYPOTHESIS

Safety concerns with the use of mesh in vaginal surgery have been ongoing. Autologous fascial slings (AFS) avoid foreign body complications. We compared the long-term (17-year) outcomes of two AFS repair methods-the standard sling and short sling (sling-on-string), and assessed durability and patient satisfaction of these for the treatment of stress urinary incontinence (SUI).

METHODS

A total of 107 patients from three urogynaecology units who had participated in a randomised controlled trial assessing standard (n = 52) and short (n = 55) slings were followed up for a median period of 17 years. Primary outcomes were Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) scores to assess the impact on the quality of life and symptom distress. Logistic quantile regression was employed to compare the two methods. Secondary outcomes included long-term complications and patient satisfaction.

RESULTS

Mean scores showed no statistically significant difference between the standard and short slings at the 17-year follow-up relating to IIQ and UDI scores, leakage or urgency (p > 0.05). Improved bladder function was observed at 17 years compared with baseline (standard sling-IIQ scores mean difference [MD] 1.22 [CI: 0.69, 1.74], UDI scores MD 0.83 [CI: 0.70, 0.97]; short sling-IIQ score MD 1.14 [CI: 0.73, 1.54], UDI scores MD 0.54 [CI: 0.40, 0.67]) with age-related deterioration over time. Re-operation rates were low and patient satisfaction rates were high (67.2%) at follow-up.

CONCLUSIONS

Autologous fascial slings are an effective and durable option for management of SUI and the short sling procedure can be recommended owing to plausible surgical advantages.

Ultra Long-term Follow-up of the Autologous Pubovaginal Sling for Stress Incontinence: Results at 23 Years

OBJECTIVE

To examine the efficacy, safety, and long-term durability of the autologous pubovaginal sling for stress incontinence over a 29-year period.

METHODS

A total of 192 consecutive female patients with stress urinary incontinence who underwent autologous pubovaginal sling from 1993 through 1999 were analyzed over a 29-year period. Intermediate and ultra long-term follow-up were obtained at a mean of 4 and 23 years, respectively. A total of 51 patients had sufficient data at both time intervals and were evaluated using a standardized questionnaire for resolution of stress incontinence, the primary endpoint, as well as resolution of urge incontinence, overall dryness, and voiding dysfunction.

RESULTS

At intermediate-term follow-up (mean 45.3 months), 96% of 51 patients reported no stress incontinence. In addition, 76% of patients experienced resolution of their preoperative urge incontinence. Overall dryness occurred in 84%. At ultra long-term follow-up (mean 22.9 years), 84% reported no stress incontinence and an overall dryness rate of 53%. Postoperative voiding dysfunction included de novo urge incontinence (3 patients) and persistent urinary obstruction requiring urethrolysis (1 patient).

CONCLUSION

The autologous pubovaginal sling is effective, safe, and durable at a mean of 23 years, the longest known follow-up in the literature. Given the U.S. Food and Drug Administration (FDA) warnings regarding transvaginal mesh and growing concerns with the synthetic midurethral sling, the autologous pubovaginal sling should be offered as an option to those women seeking treatment for stress urinary incontinence.

Long-term outcomes of surgical interventions for stress urinary incontinence: a systematic review and network meta-analysis

BACKGROUND

Stress urinary incontinence is common among women, and surgical interventions have significantly improved patients' symptoms. The long-term effectiveness of these surgeries is increasingly drawing attention, yet it remains sparsely documented in the literature.

OBJECTIVE

To compare the long-term effectiveness and safety of retropubic tension-free vaginal tape (TVT-RP), tension-free vaginal tape-obturator (TVT-O), transobturator tape (TOT), single-incision sling (SIS), Burch colposuspension, and pubovaginal sling (PVS).

METHODS

A comprehensive and systematic literature review was conducted in PubMed, EMBASE, MEDLINE, Cochrane Library, Medicine, and clinicaltrials.gov from inception to May 2023. Selected trials were evaluated for potential bias using the Cochrane tool. Treatment modalities were compared using network meta-analysis to assess objective success rate, subjective success rate, and complications as outcomes.

RESULTS

A total of 37 studies involving 5720 patients were included. No significant statistical differences were found among the interventions regarding objective success rate. PVS had the highest surface under the cumulative ranking curve SUCRA value (93.1). For subjective success rate, TVT-RP, TVT-O, and PVS demonstrated superiority over SIS, with PVS having the highest SUCRA value (80.1). SIS had lower overall complication and pain rates compared to other methods, with statistical significance. There were no differences in reoperation rate, exposure rate, and urinary tract infection occurrence among the surgical approaches.

CONCLUSIONS

In terms of long-term effectiveness and safety, TVT-RP and TVT-O appear to be the preferred options for patients opting for synthetic slings, while for patients seeking nonsynthetic slings, PVS may represent the optimal choice.

Surgical Treatments for Women with Stress Urinary Incontinence: A Systematic Review

Stress urinary incontinence affects a large proportion of women in their lifetime. The objective of this review was to describe and compare the latest surgical trends in urinary incontinence and focus on the literature advantages, disadvantages, complications and efficacy of surgical procedures regarding this pathology. Using network meta-analysis, we have identified the most frequently used procedures (Burch surgery, midurethral sling and pubovaginal sling), and we have described and characterized them in terms of effectiveness and safety. Midurethral procedures remain the gold standard for surgical treatment of stress urinary incontinence, although the potential of serious complications following this procedure should be taken into consideration always. There is a clear need for a much more unified evaluation of possible complications and postoperative evolution. This process will help practitioners to adapt and individualize their strategy for each patient.

Cost-effectiveness Analysis: Autologous Rectus Fascial Sling Versus Retropubic Midurethral Sling for Female Stress Urinary Incontinence

IMPORTANCE

There are limited data on the economic comparison between retropubic midurethral sling and autologous fascial sling.

OBJECTIVE

This study aims to evaluate the cost-effectiveness of autologous rectus fascial sling compared with retropubic midurethral sling from both hospital and health care perspectives.

STUDY DESIGN

A decision tree model was developed with 1 year of follow-up. We included variables such as objective success rate, complications and subsequent treatments, and retreatment for incontinence. The model included the index procedure and 1 retreatment for stress urinary incontinence. Cost estimates were calculated from both hospital and health care perspectives. The outcomes were expressed in incremental cost-effectiveness ratio (ICER) or cost per quality-adjusted life-year (QALY). An ICER <$50,000/QALY was considered cost-effective.

RESULTS

From a hospital perspective, the overall cost of retropubic midurethral sling was higher than autologous rectus fascial sling ($2,348.94 vs $2,114.06), but was more effective (0.82 vs 0.80 QALYs). The ICER was $17,452/QALY. From a health care perspective, the overall cost of autologous rectus fascial sling was higher than retropubic midurethral sling ($4,656.63 vs $4,630.47) and was less effective. Retropubic midurethral sling was the dominant strategy, with ICER of -$1,943.32/QALY. If the success rate of autologous rectus fascial sling was ≥84.39%, or the cost of retropubic midurethral sling surgery was > $2,654.36, then autologous rectus fascial sling would become cost-effective.

CONCLUSIONS

Retropubic midurethral sling is the cost-effective treatment from the hospital perspective and the dominant treatment from the health care perspective. However, changes in the costs and success rates of surgical procedures can alter the cost-effectiveness results.

A preliminary evaluation of in vivo response to a filament-wound macroporous collagen midurethral sling in an ovine model

Stress urinary incontinence (SUI) impacts ~1/3 of women over age 50. Negative publicity around PP meshes used in pelvic prolapse repair drives the need for identifying alternative biomaterials for SUI repair. Our study evaluated in vivo response to collagen sling implanted in an ovine model. Electrocompacted collagen threads were filament wound as slings and crosslinked in genipin. Collagen slings were implanted suburethrally mimicking the transvaginal tape technique. Main study groups were: Collagen sling (n = 3, 6 months) and PP sling (n = 3, 6 months). Collagen sling was also tested at 3-weeks (n = 1) to observe early-stage tissue response and 1-year (n = 2) to assess biomaterial longevity in a preliminary capacity. Collagen slings healed to a fibrous ligament texture at 6 months and maintained such texture to 1 year. Histological scoring indicated biocompatible responses to collagen slings with no adverse events. All study groups exhibited complete tissue ingrowth and interstitial de novo collagen deposition at all time points. Collagen threads induced orderly de novo collagen deposition that was aligned along long axes of threads. Tissue infiltrated collagen slings that were explanted at 6 and 12 months presented similar structural strength with native tissues such as vagina and fascia, and PP (Lynx) slings (p > .05). With the limitation of low number of animals per time point in hindsight, this preliminary study justifies evaluation of collagen slings in a larger sample size of animals, particularly to assess persistence of ligamentous tissue response over longer durations than 1-year.

The efficacy and complications of retropubic tension‐free vaginal tapes after twenty years: a prospective observational study

OBJECTIVE

Long-term data regarding risks associated with tension-free vaginal tapes (TVT) are sparse, and where available are limited to small numbers. We analyse patient-reported outcomes of TVT after 16-24 years.

DESIGN

Prospective observational study.

SETTING

Single-centre study in a tertiary referral urogynaecology unit.

POPULATION

A cohort of 350 women who had a TVT inserted between 1999 and 2004, in which 96% had urodynamically proven stress incontinence.

METHODS

Postal questionnaire survey using the International Consultation on Incontinence Questionnaire, a visual analogue scale and a yes/no question as to whether they would have the procedure again.

MAIN OUTCOME MEASURES

The primary outcome was cure of stress urinary incontinence, which was assessed using the ICIQ-FLUTS questionnaire. Secondary outcomes included overactive bladder symptoms, pain, sexual dysfunction, and patient satisfaction with the procedure.

RESULTS

A total of 183/350 (52%) responses were received. The median age of women at follow up was 67 years (range 53-93 years) and the median follow up was 20 years (17-24 years). Stress urinary incontinence was denied by 39.3% of women. Urgency was reported by 42.1%. Bladder pain was reported either 'never' or 'occasionally' by 92.3% of women. The median satisfaction rate was 98/100 and 92.4% said they would have the TVT procedure again.

CONCLUSIONS

Tension-free vaginal tape has high levels of satisfaction and cure up to 24 years after placement. Pain was uncommon and its impact on quality of life was low. Symptoms of urgency were prevalent but may be related to age. TVT is an effective treatment for SUI more than 20 years after initial placement.

Minimally Invasive Autologous Fascia Sling at the Midurethra: A Case Series

STUDY OBJECTIVE

The primary objective was to determine the improvement in stress urinary incontinence symptoms using autologous fascia lata sling placed at the midurethra. The secondary objective was to determine the presence of leg pain after harvest of fascia lata graft.

DESIGN

Case series.

SETTING

Rural academic tertiary care center.

PATIENTS

All women who underwent an autologous fascia midurethral sling over a 1-year period between June 2019 and September 2020.

INTERVENTIONS

Autologous fascia lata midurethral sling.

MEASUREMENTS

Incontinence severity index, urodynamic distress inventory-6, and Likert pain scale.

MAIN RESULTS

Nineteen women received an autologous fascial sling at the midurethra using the described technique-16 fascia lata and 3 rectus fasciae. Mean improvement in incontinence severity index score was 6 points. Mean improvement in urodynamic distress inventory-6 and SUI subscale scores was 14 and 53, respectively, surpassing the minimally important difference for each. Median follow-up time was 9 months (range 2-16). Leg pain at the harvest site was bothersome in 1 patient beyond 6 weeks. Median time to passing voiding trial was 4 days (range 1-13 days). Four patients (21%) had postoperative voiding dysfunction, 3 of which resolved after sling loosening at a mean of 60 days after sling placement.

CONCLUSION

Midurethral autologous fascial sling placement significantly improves symptoms of SUI but carries a risk of voiding dysfunction. Harvesting fascia lata using a fascial stripper is associated with minimal postoperative morbidity.

Use of Magnetic Resonance Imaging in women with suspected complications following insertion of implants for pelvic organ prolapse and stress urinary incontinence surgery

OBJECTIVE

To evaluate the role of Magnetic Resonance Imaging (MRI) in women presenting with suspected implant complications following surgery for pelvic organ prolapse (POP) and stress urinary incontinence (SUI).

STUDY DESIGN

Retrospective single-centre cohort study in a designated tertiary referral centre. All women with vaginally and/or abdominally placed implants for POP or SUI who were referred with suspected mesh complications, and investigated with an MRI scan, between January 2018-October 2020 were included in the study.

RESULTS

97 women were identified over this time-period with a total of 123 implants, a median age of 55 years (Range: 34-79) and an average insertion to presentation time of 84 months (Range: 2-300). 78% (74) had one implant in situ, with the remainder having at least 2 in situ. Transobturator tapes (TVT-O/TOT) were the most common implants [35% (43)]. Chronic Pelvic or abdominal pain was the most common clinical symptom [73.2% (71/112 primary complaints)] with provoked tenderness on examination being the most common clinical finding [27.8% (32/115 clinical findings)]. MRI was more likely to detect abdominally placed implants [100% (all 30)] and Retropubic Tapes [89% (16/18)] when compared to Transvaginal POP implants [87.5% (28/32)] and TVT-O/TOT [67% (29/43)]. MRI identified both cases of Sacrocolpopexy mesh rupture as well as all 11 cases of infection (100%). In 91% (10/11) of these cases, MRI revealed the infection to be more widespread than clinical findings initially suspected. Cohen's Kappa demonstrated excellent correlation between MRI and surgical findings in cases with implant related infection, rupture and normal findings (κ = 1; z = 4.58; p = 0.00000459).

CONCLUSION(S)

MRI can be a useful tool in assessment and management of patients with complications from implants. MRI can detect infection that may be more extensive that is initially clinically apparent in the outpatient setting. Abdominal implants appear to be easier to detect than transvaginal meshes and trans obturator tapes.

Very long-term follow-up of autologous pubovaginal fascia slings in women with stress urinary incontinence

INTRODUCTION AND HYPOTHESIS

The objective was to report on the very long-term outcome of a published series of autologous pubovaginal slings (PVS) in women with stress urinary incontinence (SUI).

METHODS

Following institutional review board approval, a cohort of well characterized, non-neurogenic women who underwent an autologous PVS (primary [PVS1] and secondary [PVS2]) for SUI was re-evaluated for their very long-term outcome status. Data collected included demographics, validated questionnaires (Urogenital Distress Inventory - short form [UDI-6], Incontinence Impact Questionnaire - short form 7, quality of life), SUI retreatment/operations, and subjective patient-reported SUI improvement (%) and symptom recurrence. The primary outcome was success defined as UDI-6 question 3 (SUI) ≤ 1 and no SUI retreatment/operation. Patients not seen in clinic for 2 years were contacted via a standardized phone interview.

RESULTS

From 83 patients with 7-year intermediate follow-up data, 34 (PVS1 = 18, PVS2 = 16) had very long-term follow-up based on clinic visit (7) or phone interviews (27). Those lost to follow-up (49), including 5 deceased, did not differ in demographics and intermediate outcomes from the followed cohort, but lived further away (>75 miles). At a mean age of 74 years, and with a median follow-up of 14.5 years, 53% met the success criteria (PVS1 = 44%, PVS2 = 63%). Mean postoperative questionnaire scores did not differ significantly between intermediate and very long-term follow-ups, and long-term outcomes between PVS1 and PVS2 remained similar.

CONCLUSIONS

A majority of women with long-term follow-up after PVS for primary and secondary SUI remained successful more than 14 years after their surgery. Both groups, PVS1 and PVS2, fared equally well, confirming the durability of PVS as a treatment alternative for SUI.

European Association of Urology Guidelines on the Diagnosis and Management of Female Non-neurogenic Lower Urinary Tract Symptoms. Part 1: Diagnostics, Overactive Bladder, Stress Urinary Incontinence, and Mixed Urinary Incontinence

CONTEXT

Female lower urinary tract symptoms (LUTS) are a common presentation in urological practice. Thus far, only a limited number of female LUTS conditions have been included in the European Association of Urology (EAU) guidelines compendium. The new non-neurogenic female LUTS guideline expands the remit to include these symptoms and conditions.

OBJECTIVE

To summarise the diagnostic section of the non-neurogenic female LUTS guideline and the management of female overactive bladder (OAB), stress urinary incontinence (SUI), and mixed urinary incontinence (MUI).

EVIDENCE ACQUISITION

New literature searches were carried out in September 2021 and evidence synthesis was conducted using the modified GRADE criteria as outlined for all EAU guidelines. A new systematic review (SR) on OAB was carried out by the panel for the purposes of this guideline.

EVIDENCE SYNTHESIS

The important considerations for informing guideline recommendations are presented, along with a summary of all the guideline recommendations.

CONCLUSIONS

Non-neurogenic female LUTS are an important cause of urological dysfunction. Initial evaluation, diagnosis, and management should be carried out in a structured and logical fashion based on the best available evidence. This guideline serves to present this evidence to health care providers in an easily accessible and digestible format.

PATIENT SUMMARY

This report summarises the main recommendations from the European Association of Urology guideline on symptoms and diseases of the female lower urinary tract (bladder and urethra) not associated with neurological disease. We cover recommendations related to diagnosis of these conditions, as well as the treatment of overactive bladder, stress urinary incontinence, and mixed urinary incontinence.

Autologous fascial slings remain viable at long-term follow-up: a post cystectomy case report

BACKGROUND

Autologous fascial slings (AFS) have been used for a very long time in the treatment of female stress urinary incontinence, but the introduction of synthetic mesh slings placed either retropubicallyor trans-obturator has decreased the need to harvest the autologous rectus muscle fascia, thus reducing invasiveness and operative time. However AFS are still indicated in complicated cases and re-interventions, and the FDA has underlined safety concerns over the use of surgical meshes for the transvaginal repair of prolapsed pelvic organs.

CASE PRESENTATION

A 76-year-old woman with muscle-invasivebladder cancer underwent radical cystectomy 16 years after retropubic positioning of an autologous rectus muscle fascial sling for SUI, with complete symptom resolution. The sling was easily identified and removed en bloc with the bladder and urethra, providing an opportunity to histologicallyevaluate the autologous fascial graft after its long permanence in the new position. Histopathological examination demonstrated increased fibroblastic proliferation and formation of capillaries. A slight separation and an increased waviness of the connective fibers were both evident. An increased vascularity was also apparent, including transverse vessels, with clusters of vessels. A relative inflammatory reaction was present in over 300 cells/10 HPF. All these characteristics indicated viable connective tissue.

CONCLUSIONS

AFS remain a valuable surgical option for both primary and recurrent SUI in women, showing high cure rates and low complications in the long-term. The present case, to the best of our knowledge, presents the longest follow-up period of an autologous rectus muscle fascia placed retropubically and its histological evaluation documents characteristics which support its mechanical strength and viability.

Modified autologous fascial sling technique ('sling on a string') for stress incontinence

Introduction and hypothesis

Describe the modified autologous fascial sling procedure that has been employed in the largest randomized controlled trial comparing autologous slings, mesh slings and xenografts.

Methods

The video aims to demonstrate the modified Aldridge technique. The surgical procedure is demonstrated. A 6-cm suprapubic incision is made to harvest the rectus sheath fascia. Loop-0-PDS sutures are attached on either end of the sling. A marking suture is placed in the middle of the graft to facilitate tension-free adjustment. A vaginal incision is made at the mid-urethra. Paraurethral dissection is performed to create a tunnel for the fascial graft to be passed through (in the same manner as with transvaginal mesh slings). The ends of the graft PDS sutures are passed through the paraurethral tunnel. One hand is placed abdominally below the rectus muscles to palpate the pelvic floor from above. The graft sutures are passed through the pelvic floor with control on either side. A cystoscopy is performed to check the bladder integrity. The graft placement is adjusted to be tenson-free. The incisions are closed. The short- and long-term outcomes of this technique have been investigated and published.

Results

The cure rates and complication rates were no different in the mesh and autologous slings. The xenograft had inferior outcomes.

Conclusion

Autologous fascial slings can be used in the surgical management of urodynamic stress incontinence. The technique demonstrated in this video is the technique employed in the largest randomized controlled trial investigating the efficacy of autologous fascial slings to xenografts and tapes.

Is There Outcome Reporting Heterogeneity in Trials That Aim to Assess the Effectiveness of Surgical Treatments for Stress Urinary Incontinence in Women?

CONTEXT

Inconsistent reporting of effectiveness outcomes in surgical trials of stress urinary incontinence (SUI) has hindered direct comparisons of various surgical treatments for SUI.

OBJECTIVE

To systematically review the verbatim outcome names, outcome definitions, and tools used to measure the outcomes in surgical trials of SUI in women.

EVIDENCE ACQUISITION

Trials of women with SUI who have undergone surgical interventions were included. We conducted a systematic review (SR) on outcomes reported in randomized controlled trials of surgical management published in 2014-2019, covering the following databases: MEDLINE, EMBASE, CENTRAL, and CDSR. Verbatim outcome names extracted from the included studies were categorized and then grouped into domains using the Williamson-Clarke (W/C) outcome taxonomy. A matrix was also created to visualize and quantify the dimensions of outcome reporting heterogeneity in SUI trials.

EVIDENCE SYNTHESIS

A total of 844 verbatim outcome names were extracted, of which, 514 varied terms were reduced to 71 standardized outcome names. They were further categorized into 11 domains from the W/C taxonomy. There were 7.24 different terms on average to describe each outcome, and the four outcomes with the most heterogeneity evident in terms used to describe them were "urinary retention", "reoperation", "subjective cure rate" and "quality of life". Each of them had ≥20 different terms. Only 28% of the outcome definitions were reported and a variety of measuring tools was noted, particularly in subjective outcomes. High heterogeneity was found in the outcome names, outcome definitions, choice and number of measuring instruments of the outcomes, and choice and number of outcomes reported across studies.

CONCLUSIONS

This SR provides objective evidence of heterogeneity in outcome reporting in SUI surgical trials. Our categorization of outcomes highlights the difficulties in summarizing the current evidence base. A core outcome set, developed using the methods advocated by the Core Outcome Measures in Effectiveness Trials (COMET) and COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) initiatives, is required.

PATIENT SUMMARY

In this research, we have highlighted the diversity in outcomes reporting in stress urinary incontinence (SUI) surgical trials and have categorized the outcomes. We support the development of a core outcome set for SUI, which will promote future clinical researchers to measure the same outcome in the same way in all trials. This will, in turn, help researchers summarize the evidence more effectively and aid decision making for patients and doctors.

Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition)

The present article is an abridged English translation of the Japanese Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition), published in September 2019. These guidelines consist of a total of 212 pages and are unique worldwide in that they cover female lower urinary tract symptoms other than urinary incontinence. They contain two algorithms for "primary treatment" and "specialized treatment," respectively. These guidelines, consisting of six chapters, address a total of 26 clinical questions including: (i) treatment algorithms; (ii) what are female lower urinary tract symptoms?; (iii) epidemiology and quality of life; (iv) pathology and illness; (v) diagnosis; and (vi) treatment. When the patient's symptoms mainly involve voiding and post-micturition symptoms, specialized treatment should be considered. In the event of voiding symptoms concurrent with storage symptoms, residual urine should be measured; if the residual urine volume is <100 mL, then diagnosis and treatment for storage symptoms is prioritized, and if the volume is ≥100 mL, then specialized treatment should be considered. When storage symptoms are the primary condition, then the patient is subject to the primary treatment algorithm. Specialized treatment for refractory overactive bladder includes botulinum toxin injection and sacral nerve stimulation. For stress urinary incontinence, surgical treatment is indicated, such as urethral slings. The two causes of voiding symptoms and post-micturition symptoms are lower urinary tract obstruction and detrusor underactivity (underactive bladder). Mechanical lower urinary tract obstruction, such as pelvic organ prolapse, is expected to improve with surgery.

Female stress urinary incontinence surgery: 'Resurgence of the Titans'

OBJECTIVE

To evaluate the trends in female stress urinary incontinence (SUI) surgery in a UK tertiary referral center during five years before the July 2018 tape suspension and to compare it with National Health Service (NHS) England data.

MATERIALS AND METHODS

A retrospective study of female SUI procedures (bulking agents, mid-urethral sling [MUS], colposuspension, autologous fascial sling) in a single UK tertiary referral center between 2013 and 2018. The treatment choice was made through shared decision-making on the basis of national standardized information leaflets, patient's own research, and discussion/clarification with the surgeon. Data on NHS England SUI surgery between 2012 and 2018 were extracted from a retrospective review of the hospital episode statistics.

RESULTS

Between 2013 and 2018, 448 procedures for SUI were performed at our center. In contrast to a significant 31% decline in the total number of SUI procedures in NHS England in that time period, no decline in the number of SUI procedures occurred in our center. However, the distribution of SUI procedures did change significantly. MUS procedures declined significantly (46% total and 45% relative), whereas bulking agents and colposuspensions showed a clear relative rise (+11% and +30%). The distribution of SUI procedures in NHS England also changed significantly with a decline in MUS procedures (39% total and 11% relative) and an increase in bulking agents (82% total and 9% relative).

CONCLUSION

When all invasive treatment options are transparently presented to female patients with SUI, they prefer other surgical treatments as an alternative to MUS.

Autologous Fascial Slings for Surgical Management of Stress Urinary Incontinence: A Come Back

Stress urinary incontinence (SUI) is a common type of urinary incontinence adversely affecting the quality of life of women. For mild SUI, life style changes, pelvic floor exercises and medical treatment with duloxetine may help. Most patients of moderate to severe SUI usually require surgical treatment. Various surgical treatment options include Kelly's plication, Burch colposuspension, bulking agents and sling surgeries. Although, suburethral fascial slings including the autologous rectus fascia slings were in vogue before 1990, they were overtaken by minimally invasive, faster and easier artificial midurethral slings (tension free vaginal tape and transobturator tape). However, observation of serious long-term and life changing complications of synthetic midurethral slings like mesh erosion, chronic pelvic pain and dyspareunia led to their adverse publicity and medico legal implications for the operating surgeons. This led US FDA (Food and Drug Administration) to issue a warning against their use. Currently, their use has significantly decreased in many countries, and they are no longer available in some countries. This has led to renaissance of use of natural autologous fascial sling, especially rectus fascia for surgical management of SUI. Although performing rectus fascia sling surgery is technically more challenging, takes longer, has more short-term morbidity like voiding dysfunction, their long-term success is high with very little risk of serious complications like mesh erosion, chronic pelvic pain and dyspareunia. However, multicentric trials and longer follow ups are needed before it's routine recommendation This review discusses the role of autologous fascial sling (especially rectus fascia) for the surgical management of SUI in the current time and the need of ongoing training of this procedure to gynecology residents and urogynecology fellows.

Current Use of the Artificial Urinary Sphincter in Adult Females

PURPOSE OF REVIEW

The aim of the present report was to review the recent evidences regarding the use of artificial urinary sphincter (AUS) in adult females.

RECENT FINDINGS

While the excellent functional outcomes of AUS in female patients with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD) have been reported for decades, its use has remained confidential in most countries likely due to its challenging implantation and inherent morbidity. Over the past few years, laparoscopic and, more recently, robotic techniques of AUS implantation in female patients have been described with promising perioperative outcomes. As a result, the use of AUS has increased in several countries. The indications are mostly recurrent or persistent SUI after previous anti-incontinence procedures and neurogenic SUI. Owing to its unique potential to restore continence while maintaining low outlet resistance during the voiding phase, AUS may be of special interest in female patients with detrusor underactivity. High level of evidence data from trials which are underway, along with developments in robotic surgery and technological refinements of the device, may well, almost 50 years after its introduction, give to the AUS its momentum as a major contributor in the female SUI armamentarium. While the use of AUS in female patients has been restricted to some countries and a few high-volume centers, it has started spreading again over the past few years, thanks to the rise of minimally invasive approaches which facilitate its implantation, and this is yielding promising outcomes.

Tissue engineering in female pelvic floor reconstruction

Pelvic organ prolapse is a common and frequently occurring disease in middle-aged and elderly women. Mesh implantation is an ideal surgical treatment. The polypropylene mesh commonly used in clinical practice has good mechanical properties, but there are long-term complications. The application of tissue engineering technology in the treatment of pelvic organ prolapse disease can not only meet the mechanical requirements of pelvic floor support, but also be more biocompatible than traditional polypropylene mesh, and can promote tissue repair to a certain extent. In this paper, the progress of tissue engineering was summarized to understand the application of tissue engineering in the treatment of pelvic organ prolapse disease and will help in research.

Traditional suburethral sling operations for urinary incontinence in women

BACKGROUND

Stress urinary incontinence constitutes a significant health and economic burden to society. Traditional suburethral slings are surgical operations used to treat women with symptoms of stress urinary incontinence.

OBJECTIVES

To assess the effectiveness of traditional suburethral sling procedures for treating stress urinary incontinence in women; and summarise the principal findings of relevant economic evaluations.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), as well as MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP); we handsearched journals and conference proceedings (searched 27 February 2017) and the reference lists of relevant articles. On 23 January 2019, we updated this search; as a result, several additional reports of studies are awaiting classification.

SELECTION CRITERIA

Randomised or quasi-randomised trials that assessed traditional suburethral slings for treating stress or mixed urinary incontinence.

DATA COLLECTION AND ANALYSIS

At least two review authors independently extracted data from included trials and assessed risk of bias. When appropriate, a summary statistic was calculated: risk ratio (RR) for dichotomous data, odds ratio (OR) for continence and cure rates that were expected to be high, and mean difference (MD) for continuous data. We adopted the GRADE approach to assess the quality of evidence.

MAIN RESULTS

A total of 34 trials involving 3244 women were included. Traditional slings were compared with 10 other treatments and with each other. We did not identify any trials comparing suburethral slings with no treatment or sham treatment, conservative management, anterior repair, or laparoscopic retropubic colposuspension. Most trials did not distinguish between women having surgery for primary or recurrent incontinence. One trial compared traditional slings with bladder neck needle suspension, and another trial compared traditional slings with single-incision slings. Both trials were too small to be informative. Traditional suburethral sling operation versus drugs One small trial compared traditional suburethral sling operations with oxybutynin to treat women with mixed urinary incontinence. This trial did not report any of our GRADE-specific outcomes. It is uncertain whether surgery compared with oxybutynin leads to more women being dry (83% vs 0%; OR 195.89, 95% confidence interval (CI) 9.91 to 3871.03) or having less urgency urinary incontinence (13% vs 43%; RR 0.29, 95% CI 0.09 to 0.94) because the quality of this evidence is very low. Traditional suburethral sling versus injectables One small trial compared traditional slings with suburethral injectable treatment. The impact of surgery versus injectables is uncertain in terms of the number of continent women (100% were dry with a traditional sling versus 71% with the injectable after the first year; OR 11.57, 95% CI 0.56 to 239.74), the need for repeat surgery for urinary incontinence (RR 0.52, 95% CI 0.05 to 5.36) or the occurrence of perioperative complications (RR 1.57, 95% CI 0.29 to 8.49), as the quality of evidence is very low. Traditional suburethral sling versus open abdominal retropubic colposuspension Eight trials compared slings with open abdominal retropubic colposuspension. Moderate-quality evidence shows that the traditional suburethral sling probably leads to more continent women in the medium term (one to five years) (69% vs 59% after colposuspension: OR 1.70, 95% CI 1.22 to 2.37). High-quality evidence shows that women were less likely to need repeat continence surgery after a traditional sling operation than after colposuspension (RR 0.15, 95% CI 0.05 to 0.42). We found no evidence of a difference in perioperative complications between the two groups, but the CI was very wide and the quality of evidence was very low (RR 1.24, 95% CI 0.83 to 1.86). Traditional suburethral sling operation versus mid-urethral slings Fourteen trials compared traditional sling operations and mid-urethral sling operations. Depending on judgements about what constitutes a clinically important difference between interventions with regard to continence, traditional suburethral slings are probably no better, and may be less effective, than mid-urethral slings in terms of number of women continent in the medium term (one to five years) (67% vs 74%; OR 0.67, 95% CI 0.44 to 1.02; n = 458; moderate-quality evidence). One trial reported more continent women with the traditional sling after 10 years (51% vs 32%: OR 2.22, 95% CI 1.07 to 4.61). Mid-urethral slings may be associated with fewer perioperative complications (RR 1.74, 95% CI 1.16 to 2.60; low-quality evidence). One type of traditional sling operation versus another type of traditional sling operation Nine trials compared one type of traditional sling operation with another. The different types of traditional slings, along with the number of different materials used, mean that trial results could not be pooled due to clinical heterogeneity. Complications were reported by two trials - one comparing non-absorbable Goretex with a rectus fascia sling, and the second comparing Pelvicol with a rectus fascial sling. The impact was uncertain due to the very low quality of evidence.

AUTHORS' CONCLUSIONS

Low-quality evidence suggests that women may be more likely to be continent in the medium term (one to five years) after a traditional suburethral sling operation than after colposuspension. It is very uncertain whether there is a difference in urinary incontinence after a traditional suburethral sling compared with a mid-urethral sling in the medium term. However, these findings should be interpreted with caution, as long-term follow-up data were not available from most trials. Long-term follow-up of randomised controlled trials (RCTs) comparing traditional slings with colposuspension and mid-urethral slings is essential. Evidence is insufficient to suggest whether traditional suburethral slings may be better or worse than other management techniques. This review is confined to RCTs and therefore may not identify all of the adverse effects that may be associated with these procedures. A brief economic commentary (BEC) identified three eligible economic evaluations, which are not directly comparable due to differences in methods, time horizons, and settings. End users of this review will need to assess the extent to which methods and results of identified economic evaluations may be applicable (or transferable) to their own setting.

Do we need better information to advise women with stress incontinence on their choice of surgery? Report from the ICI-RS 2018

AIMS

The regulatory warnings about the safety of the synthetic midurethral slings (MUS) had a significant effect on how patients and physicians approach surgical management of stress urinary incontinence (SUI). In this changing landscape, the purpose of this research Think Tank (TT) was to provide an update of the current knowledge about the safety and efficacy of SUI surgery, to review patient goals and expectations and to identify factors affecting the decision making for surgery.

METHODS

This is a consensus report of the proceedings of TT3: "Do we need better information to advise women with stress incontinence on their choice of surgery?" from the annual International Consultation on Incontinence-Research Society (ICI-RS), June 2018.

RESULTS

Despite the body of evidence supporting the continued use of MUS, the short follow-up of most of the studies and the lack of "real life" data regarding pain and sexual dysfunction make the development of recommendations challenging. Women with SUI are often happy to "trade" efficacy for a procedure with less associated morbidity and therefore it is not always the procedure with the highest success rate that is ultimately chosen. However, a number of factors influence treatment decision and there is limited evidence about what level of all these factors women are willing to tolerate for a given success rate, or how much success they are willing to trade for a lower complication rate.

CONCLUSIONS

The ICI-RS proposed research questions which may be able to assist in improving the counseling and management of women with SUI.

Old wine into new wineskins: an update for female stress urinary incontinence

PURPOSE OF REVIEW

To review minimally invasive modifications of traditional surgeries for female stress urinary incontinence (SUI) in light of increased demand.

RECENT FINDINGS

Prior to the synthetic mid-urethral sling (MUS), traditional procedures were used to correct SUI. Often these were retropubic colposuspension procedures for a hypermobile urethra and fascial slings for sphincter deficiency but fell out of favor because of increased morbidity compared with synthetic MUS. As controversy rages over use of mesh in female pelvic reconstructive surgery, more women desire nonmesh alternatives. Traditional approaches have been modified to enable colposuspensions and fascial slings to be performed minimally invasively without minimizing efficacy.

SUMMARY

Minimally invasive modifications to traditional procedures for SUI have been available for about a decade but interest has been recently reignited in the setting of patient concern over mesh.

Managing female pelvic floor disorders: a medical device review and appraisal

Pelvic floor disorders (PFDs) will affect most women during their lifetime. Sequelae such as pelvic organ prolapse, stress urinary incontinence, chronic pain and dyspareunia significantly impact overall quality of life. Interventions to manage or eliminate symptoms from PFDs aim to restore support of the pelvic floor. Pessaries have been used to mechanically counteract PFDs for thousands of years, but do not offer a cure. By contrast, surgically implanted grafts or mesh offer patients a more permanent resolution but have been in wide use within the pelvis for less than 30 years. In this perspective review, we provide an overview of the main theories underpinning PFD pathogenesis and the animal models used to investigate it. We highlight the clinical outcomes of mesh and grafts before exploring studies performed to elucidate tissue level effects and bioengineering considerations. Considering recent turmoil surrounding transvaginal mesh, the role of pessaries, an impermanent method, is examined as a means to address patients with PFDs.

Revisiting current treatment options for stress urinary incontinence and pelvic organ prolapse: a contemporary literature review

Stress urinary incontinence (SUI) and pelvic organ prolapse (POP) affect many women in their lifetime. In this review, we describe and evaluate the latest treatment options for SUI and POP, including the controversy around transvaginal mesh (TVM) use. Growing evidence supports the utilization of pelvic floor muscle training as first-line treatment for both SUI and POP. Vaginal pessaries continue to be an effective and reversible option to manage SUI and POP symptoms. The midurethral sling remains the gold standard for surgical treatment of SUI, although patients and clinicians should acknowledge the potentially serious complications of TVM. Burch urethropexy and pubovaginal sling offer good SUI cure and may be preferred in women wishing to avoid mesh implants; however, their operative morbidities and more challenging surgical approach may limit their use. Site-specific cystocele or rectocele repairs may be indicated for isolated anterior or posterior vaginal compartment prolapse; however, in women with more severe POP, evidence supports using a vaginal native-tissue repair involving apical suspension as the primary surgical technique. Although abdominal and laparoscopic sacrocolpopexies are both effective in treating POP, their failure and mesh complication rates increase with time. There is insufficient evidence to support the widespread use of uterine-preserving surgical POP repairs at present due to the lack of long-term data. Routine TVM use is not recommended in POP surgeries and should only be considered on a case-by-case basis by trained surgeons, primarily in women with multiple risk factors for POP recurrence. In general, clinicians should individualize SUI and POP treatment options for women based on their symptoms, comorbidities, and risk factors for mesh-related complications.

Surgery for female SUI: The ICI algorithm

INTRODUCTION

Stress urinary incontinence (SUI) is common in women and can significantly impact quality of life.

METHODS

This is a review of the 6th International Consultation on Incontinence (ICI) chapter analyzing level of evidence on surgical treatment of SUI as well as the consensus algorithm that resulted from the detailed work in the committee report as of April 2017. Included studies in this review were selected to highlight the algorithm for management.

RESULTS

Non-operative and surgical treatment options exist; conservative therapies comprise first line management, but if SUI remains bothersome, surgical treatment should be considered. Bulking agents offer a minimally invasive option with moderate short-term success rates. The most commonly performed surgical treatments for SUI are mid-urethral and pubovaginal slings, with high cure rates and patient satisfaction. Retropubic suspension is a more traditional but widely accepted procedure. Single incision sling, adjustable sling, or artificial urinary sphincter may be appropriate in carefully selected patients.

CONCLUSIONS

The choice of surgical procedure should be made only after a thorough discussion and shared decision between the patient and surgeon regarding risks, benefits, and alternatives. A trial of conservative therapy should be conducted where relevant. Referral to a specialist should be considered in women with a more complex presentation.

Intraoperative and early postoperative complications in women with stress urinary incontinence treated with suburethral slings: a randomised trial

Introduction

The midurethral sling has become the current standard for the treatment of female stress urinary incontinence.

Aim

To assess intraoperative complications, early post-operative complications as well as the efficacy of tension-free vaginal tape: retropubic and trans-obturator tape procedures.

Material and methods

The analysis involved 91 tension-free vaginal tape (TVT) and 60 transobturator tape (TOT) procedures. Both groups were comparable in terms of patient characteristics, urodynamic results, and preoperative quality of life (QoL) assessment. The complications were registered, and the effectiveness of the procedures was assessed subjectively by the patients at 1-, 3-, 6- and 12-month follow-up.

Results

A significantly lower risk of intraoperative and early post-operative complications was noted in the case of TOT procedures (OR = 0.35%, 95% CI: 0.13–0.92). Moreover, regardless of the method used, patients with two or more vaginal deliveries in their history had a reduced risk of complications, as compared to nulliparas and uniparas (OR = 0.38%, 95% CI: 0.16–0.91). Previous gynaecological surgery and old age increase the risk of complications with borderline significance (OR = 2.5, 95% CI: 0.97–6.3; OR = 2.3, 95% CI: 0.95–5.5 respectively). The rates of cure, improvement and failure were similar in both groups, as was the significant positive change in post-operative life quality.

Conclusions

TVT and TOT procedures are characterised by a high cure rate and improvement in the post-operative quality of life. However, it seems that the transobturator approach should be the preferred method of treatment of SUI due to the reduced risk of complications, shorter procedure time, and lower intraoperative blood loss.

Optimising the tension of an autologous fascia pubovaginal sling to minimize retentive complications

AIM

To determine the optimal degree of pubovaginal slings (PVS) tension, measured by lax sling dimensions to minimize the risk of urinary retention.

METHODS

This prospective study analyzed female patients undergoing PVS for stress urinary incontinence (SUI) by two surgeons over 24 months from January 2016. Intra-operative measurements of lax sling dimensions tented over rectus fascia were recorded. Logistic regression was used to analyse the likelihood of urinary retention (more than 3 months of intermittent self-catheterisation (ISC) or surgical revision) for given PVS dimensions. The secondary analysis assessed for an association between PVS measurements and persistent SUI.

RESULTS

Fifty-one patients were recruited with a median age of 53 (34-78) and follow-up of 11 (3-20) months. All but one patient reported improvement of SUI. Ten (19.6%) patients developed postoperative urinary retention. Five (9.8%) resolved after a temporary period of ISC. The other five (9.8%) required ongoing ISC or sling division. A strong association existed between short sling height and prolonged urinary retention (P = 0.00). Receiver operating characteristic (ROC) curve analysis showed a sling height of 40 mm had a sensitivity of 100% and specificity of 51% for retentive complications (area under curve [AUC]  = 0.90). Lax sling height up to 60 mm was not associated with persistent SUI.

CONCLUSIONS

Stretching the sling suspension sutures at least 40 mm above the rectus fascia was associated with a lower risk of urinary retention than less than 40 mm. This simple technique would appear to be worth evaluating in a larger sample. A looser sling did not compromise the cure of SUI at a mean follow-up of 11 months.

In vivo biocompatibility and time-dependent changes in mechanical properties of woven collagen meshes: A comparison to xenograft and synthetic mid-urethral sling materials

Meshes woven from highly aligned collagen threads crosslinked using either genipin or 1-ethyl-3-(3-dimethylaminopropyl) carboiimide and N-hydroxy succinimide (EDC/NHS) were implanted in a subcutaneous rat model to evaluate their biocompatibility (at 2 weeks, 2 months, and 5 months), mechanical properties (at baseline, 2 months, and 5 months) and ultimately their suitability for use as mid-urethral slings (MUS) for management of stress urinary incontinence. Porcine dermal (Xenmatrix) and monofilament polypropylene (Prolene) meshes were also implanted to provide comparison to clinically used materials. Quantitative histological scoring showed tissue integration in Xenmatrix was almost absent, while the open network of woven collagen and Prolene meshes allowed for cellular and tissue integration. However, strength and stiffness of genipin-crosslinked collagen (GCC), Prolene, and Xenmatrix meshes were not significantly different from those of native rectus fascia and vaginal tissues of animals at 5 months. EDC/NHS-crosslinked collagen (ECC) meshes were degraded so extensively at five months that samples could only be used for histological staining. Picrosirius red and Masson's trichrome staining revealed that integrated tissue within GCC meshes was more aligned (p = 0.02) and appeared more concentrated than ECC meshes at 5 months. Furthermore, immunohistochemical staining showed that GCC meshes attracted a greater number of cells expressing markers for M2 macrophages, those associated with regeneration, than ECC meshes (p = 0.01 for CD206+ cells, p = 0.001 CD163+ cells) at 5 months.

The use of implanted materials for treating women with pelvic organ prolapse and stress urinary incontinence

PURPOSE OF REVIEW

To review the current clinical management of stress urinary incontinence and pelvic organ prolapse following the adverse complications seen in the use of polypropylene mesh to treat both.

RECENT FINDINGS

Materials developed for use in abdominal hernia repair have not proven risk-free when used to support pelvic organs particularly when inserted via the vagina. Following unacceptably high levels of severe complications when high-density polypropylene mesh is inserted via the vagina to treat pelvic organ prolapse, reported over the last decade, there is now an agreed consensus between surgeons about surgical approaches and materials, which should be recommended for use in stress urinary incontinence and pelvic organ prolapse.

SUMMARY

There is a need for new biomaterials and tissue engineered/regenerative medicine approaches to treat stress urinary incontinence and pelvic organ prolapse. New materials need to be evaluated critically in both preclinical and clinical studies before being adopted into routine clinical use.

Female stress urinary incontinence MDT

The management of female stress urinary incontinence (SUI) has come under scrutiny in recent years following growing reports of mesh-related complications. Patients require thorough evaluation and management as part of a multidisciplinary team, and extensive counselling about the surgical treatment options is imperative. There is no clear consensus on the optimal management of the complex group of patients with mesh-related complications or recurrent SUI. We present two cases of female SUI to highlight the key factors to be considered when managing these patients.

Level of evidence: Level 5.

Surgery for Stress Urinary Incontinence: Autologous Fascial Sling

This article describes the operative technique of autologous fascial pubovaginal sling (AFPVS) surgery, examines the senior author's outcomes with AFPVS, compares these outcomes with those of other large studies and meta-analyses, and compares the safety and efficacy of AFPVS with those of the synthetic midurethral sling (SMUS). Recently, the SMUS has become the treatment of choice for most surgeons. The efficacy of the SMUS remains unchallenged and comparable with that of AFPVS, but SMUS are associated with more severe complications. In the author's opinion, the AFPVS should remain the gold standard for treating SUI.

Tension-free vaginal tape-obturator for the treatment of stress urinary incontinence: a 12-year prospective follow-up

OBJECTIVE

To evaluate the long-term safety and effectiveness of inside-out transobturator tape (tension-free vaginal tape-obturator, TVT-O) for the treatment of stress urinary incontinence (SUI).

PATIENTS AND METHODS

Between August 2004 and August 2006, 87 consecutive patients with SUI who underwent TVT-O were enrolled in this prospective cohort study. Patients with mixed UI, or pelvic organ prolapse requiring surgery, were excluded. Data relating to long-term postoperative complications, subjective satisfaction rate (Patient Global Impression of Improvement), objective cure rate (stress test), quality of life (QoL), and sexual function, were collected during follow-up. The Incontinence Impact Questionnaire (IIQ-7) and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) were used to assess QoL and sexual function, respectively. Statistical analyses were performed using paired-sample t-tests.

RESULTS

At the 12-year follow-up, 73 patients (84%) were available for evaluation. Overall, the long-term complication rate was 45.2%. De novo overactive bladder was observed in 12.3% of patients. None of the patients reported severe voiding dysfunction that required treatment by tape removal or catheterisation. However, 16 patients (16/73, 21.9%) had voiding changes compared with their preoperative status. Persistent groin pain was reported in 1.4% of the patients, and tape exposure occurred in 5.5%. The subjective satisfaction rate and objective cure rate were 80.8% and 82.2%, respectively. Compared with preoperative scores, the IIQ-7 score decreased significantly (P < 0.05), whilst there was no significant difference in the PISQ-12 score (P = 0.893).

CONCLUSIONS

This 12-year follow-up study showed that TVT-O is a highly effective procedure for the treatment of SUI. The long-term complication rate appears to be slightly high, which should raise concern.

The Midurethral Fascial "Sling on a String": An Alternative to Midurethral Synthetic Tapes in the Era of Mesh Complications

BACKGROUND

Surgery for stress urinary incontinence (SUI) has been dominated recently by synthetic midurethral tapes. Increasing recognition of serious complications associated with nonabsorbable polypropylene mesh has led to resurgence in interest in alternative approaches, such as the autologous fascial sling (AFS). Despite being an efficacious and durable option in women with recurrent and complex SUI, there has been a reluctance to consider AFS in women with primary SUI due to a perception that it is only appropriate for treating patients with intrinsic sphincter deficiency (ISD) and is associated with high rates of urinary retention and de novo storage symptoms.

OBJECTIVE

The video presented demonstrates the technique for a loosely applied midurethral AFS. In contrast to AFS applied at the bladder neck, this technical modification in patients who demonstrate primary SUI without ISD avoids high rates of de novo storage symptoms and urinary retention.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective review of data on patients undergoing AFS at a tertiary referral unit.

SURGICAL PROCEDURE

AFS placement in a "loose" fashion using a short length of fascia suspended on a suture bilaterally at the midurethral level rather than at the bladder neck and only using more tension in patients with ISD.

MEASUREMENTS

Subjective cure rate, rates of postoperative storage symptoms, and urinary retention necessitating intermittent self-catheterisation (ISC).

RESULTS AND LIMITATIONS

A total of 106 patients underwent AFS; the mean follow-up period was 9 mo. The mean age was 52.6 (range 24-83) yr. In total, 46.2% had primary SUI, whilst all of the remaining 53.8% had undergone prior surgical intervention. Overall subjective cure occurred in 79.2% of patients; a further 15.1% described significant subjective improvement in symptoms, whilst 5.7% reported no change in symptoms. In those with primary SUI, rates of subjective cure, improvement, and nonresolution of symptoms were 87.8%, 12.2%, and 0%, respectively. In individuals with prior surgical intervention, rates of subjective cure, improvement, and nonresolution of symptoms were 72.0%, 17.5%, and 10.5%, respectively. De novo storage symptoms occurred in 8.2% of those with primary SUI compared with 14.0% of those with prior surgical intervention. Only 2.0% patients with primary SUI needed to perform ISC beyond 2 wk compared with 10.5% of those after prior surgery.

CONCLUSIONS

A midurethral AFS appears to be effective and safe both in women with primary SUI who want to avoid the placement of permanent material and its attendant risks, and in more complex cases where this is less appropriate.

PATIENT SUMMARY

A graft taken from the covering of the abdominal muscle or the outer aspect of the thigh is an alternative to a synthetic vaginal mesh in women who have stress urinary incontinence requiring surgical treatment. Placing the graft loosely at the midpoint of the urethral tube, rather than at the bladder neck, reduces the risk of postoperative voiding difficulty and overactive bladder symptoms. Long-term data have suggested an outcome at least as good as a synthetic nonabsorbable tape without the potential for sling erosion into adjacent structures, as it avoids the use of nonabsorbable material.

An in-house Composix™-based pubovaginal sling trial for female stress urinary incontinence: Five-year comparative followup to tension-free and transobturator vaginal tapes

INTRODUCTION

We compared the efficacy of three slings in the long-term treatment of stress urinary incontinence (SUI): tension-free vaginal tape (TVT), vaginal tape-obturator (TVT-O), and an in-house two-layered polypropylene mesh with a submicronic polytetrafluoroethylene (Composix™). Our primary endpoint was the objective measurement of continence (24-hour pad test). Secondarily, we measured the satisfaction and complication rates.

METHODS

This prospective, non-randomized study included 128 patients with SUI. Preoperative evaluation included medical history, physical exam, 24-hour pad test, Urinary Incontinence Quality of Life Scale (IQOL), FPSUND, and global satisfaction questionnaires. Patients were followed at one month postoperative, biannually for two years, and then annually for a total of five years. Followup visits included a focused questionnaire, physical exam, satisfaction questionnaire, 24-hour pad test, IQOL, and FPSUND questionnaires.

RESULTS

Composix, TVT, and TVT-O groups included 60, 34, and 34 patients, respectively. No significant differences were found in baseline characteristics except for the pad test. Length of catheterization was the only immediate operative significant parameter (Composix 4.7 days vs. TVT 1.1 days vs. TVT-O 2.6 days; p=0.03). The entire cohort had significant improvements in their IQOL, FPSUND, and pad test at one and four years (p<0.01). The cohort-wide 24-hour pad test average weight was 30.4 g preoperatively vs. 5 g at 12 months (p<0.00001) (Composix 37 to 5 g, TVT 83 to 4 g, and TVT-O 55 to 5 g). The Composix group had a higher number of minor complications (Clavien I, II) and secondary procedures.

CONCLUSIONS

This single-surgeon cohort with five-year followup demonstrated a large improvement and maintenance of continence in all three surgical groups. The Composix-based sling provided comparable continence outcomes at a fraction of the cost; however, its increased morbidity and higher complication rate raise concerns over future use.

Long-term outcomes of TOT and TVT procedures for the treatment of female stress urinary incontinence: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESES

One of the most relevant topics in the field of pelvic floor dysfunction treatment is the long-term efficacy of surgical procedures, in particular, the use of prosthesis. Hence, a systematic review and meta-analysis was conducted to evaluate the long-term effectiveness and safety of midurethral sling (MUS) procedures for stress urinary incontinence (SUI), as reported in randomised controlled trials (RCTs) and non-randomised studies.

METHODS

This systematic review is based on material searched and obtained via PubMed/Medline, Scopus, and the Cochrane Library between January 2000 and October 2016. Peer-reviewed, English-language journal articles evaluating the long-term (≥5 years) efficacy and safety of MUS in women affected by SUI were included.

RESULTS

A total of 5,592 articles were found after the search, and excluding duplicate publications, 1,998 articles were available for the review process. Among these studies, 11 RCTs (0.6%) and 5 non-RCTs (0.3%) could be included in the qualitative and quantitative synthesis. Objective and subjective cumulative cure rates for retropubic technique (TVT) and transobturator tape (TOT; both out-in and in-out) were 61.6% (95% CI: 58.5-64.8%) and 76.5% (95% CI: 73.8-79.2%), and 64.4% (95% CI: 61.4-67.4%) and 81.3% (95% CI: 78.9-83.7%) respectively. When considering TOT using the out-in technique (TOT-OI) and TOT using the in-out technique (TVT-O) the objective and subjective cumulative cure rates were 57.2% (95% CI: 53.7-60.7%) and 81.6% (95% CI: 78.8-84.4%), and 68.8% (95% CI: 64.9-72.7%) and 81.3% (95% CI: 77.9-84.7%) respectively. Furthermore, this article demonstrates that both TVT and TOT are associated with similar long-term objectives (OR: 0.87 [95% CI: 0.49-1.53], I 2 = 67%, p = 0.62) and subjective (OR: 0.84 [95% CI: 0.46-1.55], I 2 = 68%, p = 0.58) cure rates. Similarly, no significant difference has been observed between TTOT-OI and TVT-O) in objective (OR: 3.03 [95% CI: 0.97-9.51], I 2 = 76%, p = 0.06) and subjective (OR: 1.85 [95% CI: 0.40-8.48], I 2 = 88%, p = 0.43) cure rates. In addition, this study also shows that there was no significant difference in the complication rates for all comparisons: TVT versus TOT (OR: 0.83 [95% CI: 0.54-1.28], I 2 = 0%, p = 0.40), TOT-OI versus TVT-O (OR: 0.77 [95% CI: 0.17-3.46], I 2 = 86%, p = 0.73).

CONCLUSIONS

Independent of the technique adopted, findings from this systematic review and meta-analysis suggest that the treatment of SUI with MUS might be similarly effective and safe at long-term follow-up.
