Updated Systematic Review and Meta-analysis of the Comparative Data on Colposuspensions, Pubovaginal Slings, and Midurethral Tapes in the Surgical Treatment of Female Stress Urinary Incontinence

Retropubic (RP-TVT) and transobturator miurethral (TO-TVT) midurethral sling (MUS) are popular surgical treatments for female stress urinary incontinence. The long-term efficacy and safety of the procedures is still a topic of intense clinical research and several randomised controlled trials (RCTs) have been published in the last years Objective To evaluate the efficacy and safety of MUS compared with other surgical treatments for female stress urinary incontinence. Evidence acquisition A systematic review and meta-analysis of the literature was performed using the Medline, Scopus, and Web of Science databases to update our previously published analyses. Evidence synthesis Twenty-eight RCTs were identified. In total, the meta-analyses included 15 855 patients. Patients receiving MUS had significantly higher overall (odds ratio [OR]: 0.59, p =0.0003) and objective (OR: 0.51, p =0.001) cure rates than those receiving Burch colposuspension. Patients undergoing MUS and pubovaginal slings had similar cure rates. Patients treated with RT-TVT had higher subjective (OR: 0.83, p =0.03) and objective (OR: 0.82, p =0.01) cure rates than those receiving TO-TVT. However, the latter had a lower risk of intraoperative bladder or vaginal perforation (OR: 2.4, p =0.0002), pelvic haematoma (OR: 2.61, p =0.002), urinary tract infections (OR: 1.31, p =0.04) and voiding lower urinary tract symptoms (OR: 1.66, p =0.002). Sensitivity analyses limited to RCTs with follow-up durations >60 mo demonstrated similar outcomes for RP-TVT and TO-TVT. No significant differences in efficacy were identified comparing inside-to-out and outside-to-in TO-TVT but vaginal perforations were less common with the former (OR: 0.21, p =0.0002). Conclusions The present analysis confirms the superiority of MUS over Burch colposuspension. The studies comparing insertion of RT-TVT and TO-TVT showed higher subjective and objective cure rates for the RP-TVT but at the cost of higher risks of some complications and voiding lower urinary tract symptoms. Efficacy of inside-out and outside-in techniques of TO-TVT insertion was similar, although the risk of vaginal perforation was lower in the inside-to-out TO-TVT. Patient summary Retropubic and transobturator midurethral slings are a popular treatment for female stress urinary incontinence. The available literature suggest that those slings are either more effective or safer than other older surgical procedures. Retropubic tapes are followed with slightly higher continence rates as compared with the transobturator tapes but are associated with higher risk of intra- and postoperative complications.

The present analysis confirms the superiority of midurethral sling over Burch colposuspension. The studies comparing insertion of retropubic tension-free vaginal tapes and transobturator tension-free vaginal tapes (TO-
