Objective: A midurethral sling is the gold standard surgical treatment for stress urinary incontinence (SUI), however a lower success rate has been reported in the treatment of SUI after pelvic organ prolapse surgery. The aim of this study was to compare the success rates, quality of life, and complications with treatment using tension-free vaginal tape (TVT) and transobturator tape (TOT) in these patients. Materials and Methods: We enrolled patients who had symptomatic SUI after anterior vaginal mesh repair who underwent either TVT or TOT surgery. Successfully cure was defined as the absence of urinary leakage in a stress test during filling cystometry, and a negative cough test. Quality of life was evaluated using the short form of the Urinary Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). Results: We included 50 patients in the TOT group and 37 patients in the TVT group, with a median follow-up of 18.5 months. The TVT group had a significantly higher success rate than the TOT group (88% vs. 60%, p = 0.036), while there was no statistically significant difference in de novo detrusor overactivity (30% vs. 9%, p = 0.090). There was also no significant difference in postoperative quality of life (UDI-6, 5.9 ± 7.9 vs. 5.0 ± 5.9, p = 0.639; IIQ-7, 5.2 ± 12.5 vs. 4.3 ± 9.7, p = 0.766). The TVT group had a longer operative time (p < 0.001) and hospital stay (p = 0.004), however the TOT group required more repeat surgeries for recurrent SUI (p = 0.045). Conclusion: Retropubic TVT is a more effective surgical option than TOT in women with SUI after vaginal mesh repair.
