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

Abstract

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. 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). 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. 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. 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.
