PurposeThe efficacy and safety of retropubic and transobturator tension-free vaginal tape mid urethral slings remain controversial in patients with stress urinary incontinence and risk factors for recurrence. We compared the techniques after initial mid urethral sling insertion in select groups, including patients with obesity, intrinsic sphincter deficiency, pelvic organ prolapse and recurrent stress urinary incontinence.Materials And MethodsWe used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement to report the methods and results of the current review. Randomized controlled trials and observational studies were included. We assessed the objective and subjective cure rates, and the complication rate using the OR with the 95% CI. The protocol of the current meta-analysis was registered on PROSPERO (No. CRD42018102233).ResultsWe retrieved 28 studies in a total of 2,607 patients to compare the efficacy and safety of retropubic vs transobturator tension-free vaginal tape in select groups (mean followup 26.9 months). Meta-analysis of the objective cure rate showed the significant superiority of retropubic compared to transobturator tension-free vaginal tape in patients overall (OR 3.37, 95% CI 2.55-4.43, p <0.00001, I2 = 37%) and in each subpopulation. The subjective cure rate of retropubic tension-free vaginal tape was also significantly superior to that of transobturator tension-free vaginal tape in in patients overall (OR 2.01, 95% CI 1.45-2.80, p <0.0001, I2 = 0%) and in those with intrinsic sphincter deficiency and recurrent stress urinary incontinence after mid urethral sling insertion. There was no significant difference in overall complications between retropubic and transobturator tension-free vaginal tape (OR 1.22, 95% CI 0.89-1.66, p = 0.21, I2 = 0%).ConclusionsThe meta-analysis showed the superiority of retropubic tension-free vaginal tape over transobturator tension-free vaginal tape in terms of the objective and subjective cure rates in patients with obesity, intrinsic sphincter deficiency, pelvic organ prolapse and recurrent stress urinary incontinence after mid urethral sling insertion. Retropubic tension-free vaginal tape also has morbidity comparable to that of transobturator tension-free vaginal tape.
