Modified autologous transobturator tape surgery — evaluation of short term results

Autologous versus synthetic midurethral transobturator sling: A systematic review and meta-analysis of outcomes

INTRODUCTION

There have been concerns around the use of synthetic mesh for stress urinary incontinence (SUI) surgery with a renewed interest in the use of autologous tissues. Recently, an autologous transobturator sling (aTOT) has been described, but the comparative data with synthetic transobturator sling (sTOT) is limited. The objective of this systematic review and meta-analysis was to assess the outcome of aTOT and compare it with sTOT.

METHODS

A systematic search of PubMed, Scopus, and Web of Science databases was performed and all articles available up to December 31, 2023 were screened. Studies reporting on the outcomes of aTOT and those comparing aTOT with sTOT were included. This review was performed as per Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

RESULTS

Eleven studies evaluating 323 patients that met the criteria were included in the final analysis, of which 6 were single arm (155 patients) and 5 were comparative. In single-arm studies, the pooled success rate, defined as negative cough stress test at 12 months follow-up was 96.8%, 3.8% had postoperative urinary retention, 6.1% had graft site-related complications and 7.6% required additional intervention for persistent SUI. The overall complication rate was 20.6% and there were no Clavien III-V complications. aTOT had similar success and complication rates when compared with sTOT but had a significantly longer operative time (weighted mean difference: 22.35 min, p < 0.00001) and superior sexual function outcomes.

CONCLUSIONS

aTOT, at short-term follow-up (12 months), has similar efficacy and complication rates when compared to sTOT. However, given that the data is limited and not of very good quality, and the fact that long-term follow-up is not available, further studies are required to better define the role of aTOT in the management of female patients with SUI.

Evaluation of the effectiveness of transobturator tape operation in the treatment of stress incontinence

Abstract Background/Aims:: In this study, In this study, we aimed to assess the effectiveness of Transobturator Tape Operation in the treatment of Stress İncontinence Methods: We retrospectively evaluated 454 patients who had TOT operations due to stress urinary incontinence between January 1, 2017, and December 31, 2020, at the İstanbul Kanuni Traning and Research Hospital. The basic clinical characteristics of the participants were recorded. The number of daily peds, values of Q-type test and urinary retention, and scores of urogenital disorder inventory-6 and impact of incontinence inquiry form at the clinical evaluation perioperatively and 6 months after the operation. Data analysis of the study was done with the SPSS version 24.0 package program. Kolmogorov-Smirnov test was used for normality analysis. Wilcoxon test was used for the comparisons of preop and postop data. It was considered statistically significant when the P value was below 0.05 Results: The study was conducted on 454 patients aged 26-83 years with a mean age of 50.3±10 years. The overall complication rate was 15.9. The rate of those who recovered six months after the operation was 89.6%. The number of daily peds, values of Q-tip test and urinary retention, and scores of questionnaires were significantly reduced after surgery (p=0.001). Conclusions: The TOT operation can be preferred in treating stress incontinence with acceptable success and outcome. The scales of questionnaires successfully determine patient satisfaction with surgical efficacy for SUI.

Risk Factor of De Novo Urgency and Urge Incontinence After Autologous Fascia Pubovaginal Sling

Introduction

Pubovaginal sling is an efficient and safe procedure for stress urinary incontinence without the complications of synthetic sling. Urine retention and de novo urgency are bothersome aftermath of this procedure. We aim to identify potential risk factors for de novo urgency after autologous pubovaginal sling.

Methods

From 2013 to 2016, 347 patients underwent autologous pubovaginal sling. Age, BMI, pelvic irradiation, use of anticholinergic medication, previous vaginal related surgical histories, “over-tight” technique, and concomitant surgeries were examined for potential risk factors. De novo urgency/urge incontinence was defined as treatment (medication, botulinum toxin injection, sacral neuromodulation) for urge postoperatively and was not noted before surgery. Chi-square and fisher’s exact tests were used as statistical analysis.

Results

A total of 109 patients underwent autologous rectus fascia pubovaginal sling, after excluding status post urethral diverticulectomy, concomitant diverticulectomy, and concomitant abdominal surgery. Twenty-three (21.1%) patients were treated for de novo urge/urge incontinence, 18 (78.2%) with anticholinergic, 4 (17.3%) with botox injection and 2 (8.69%) with sacral neuromodulation. None but prior pelvic organ prolapse surgery was associated with developing de novo urge/urge incontinence (p=0.026).

Discussion

Patients with prior pelvic organ prolapse surgery were more likely to be at risk of de novo urgency after autologous pubovaginal sling. This study provided more information for preoperative consultation for patients undergoing incontinence surgery.

Impact of Autologous Transobturator Sling Surgery on Female Sexual Function: A Comparative Study with Mesh Used Mid-Urethral Sling Surgeries

INTRODUCTION

To avoid mesh-related complications, autologous transobturator-tape (a-TOT) technique is a viable option in stress urinary incontinence (SUI) surgery. The method differs from TOT and retropubic tape (RT) in the usage of autologous tissue. We hypothesized that a-TOT improves female sexual dysfunction (FSD) more than TOT and RT.

METHODS

This is a retrospective cohort study. Patients who underwent a-TOT, TOT, and RT surgeries were surveyed regarding the cure of SUI, complications, and FSD parameters. The groups were compared according to baseline and postoperative data.

RESULTS

A-TOT, TOT, and RT groups included 37, 69, and 36 patients, respectively. The median follow-up time was 19 months. The groups were similar in terms of preoperative characteristics. The objective cure, subjective cure, and overall complication rates were comparable among the groups (p > 0.05). A-TOT group had significant improvements in mean female sexual function index (FSFI) scores, TOT group deteriorated, and RT group remained stable (p = 0.001, p = 0.001, and p = 0.226, respectively). The postoperative mean total FSFI scores were 25.73 ± 2.46, 23.17 ± 3.35, and 21.53 ± 2.47 for the a-TOT, TOT, and RT groups, respectively. The a-TOT group had better results than the TOT and RT groups (p < 0.05 and p < 0.05), and besides, the difference between the TOT and RT groups was statistically significant (p < 0.05). According to percentage changes in domain scores following the operations, the a-TOT group had significantly better results in desire, arousal, lubrication, satisfaction, and pain domains than the TOT group (p < 0.05) as well as better desire, arousal, and pain domains (p < 0.05) than the RT group.

DISCUSSION/CONCLUSIONS

Besides comparable outcomes in SUI treatment, the a-TOT technique provides improvements in female sexual functions while TOT worsens and RT does not change. Favorable outcomes in sexual functions caused by improvements in desire, arousal, satisfaction, and pain domains are observed following the a-TOT technique.
