Long-term outcomes after sacrocolpopexy with or without transobturator tape.

Introduction And Hypothesis: The aim of this study was to report the long-term outcomes after sacrocolpopexy (SCP) with or without transobturator tape (TOT).

Methods: We conducted a planned secondary analysis of a prospective, observational study comparing urinary outcomes in women who underwent SCP with or without TOT based on the results of a prolapse-reduction stress test. Patients were enrolled between November 2008 and December 2011 and were followed up 5 years after surgery. The primary outcomes were 5-year success rates for stress urinary incontinence (SUI) and pelvic organ prolapse (POP) estimated using the Kaplan-Meier method. SUI success was defined as a negative cough stress test, no bothersome SUI symptoms, and no additional anti-incontinence surgery. POP success was defined as no vaginal bulge symptoms, no apical descent greater than one-third of the total vaginal length or anterior or posterior vaginal wall prolapse beyond the hymen, and no retreatment for prolapse.

Results: Of 240 women enrolled, 175 (73%) completed 5 years of follow-up. The estimated SUI success rate was 91.1% in the TOT group and 56.5% in the no TOT group (difference, 34.6%; 95% confidence interval, 24.1 to 45.1). The estimated POP success rate was 90.0% in the TOT group and 92.9% in the no TOT group (difference, -2.9%; 95% confidence interval, -10.7 to 4.9).

Conclusions: The advantage of concomitant TOT for SUI after SCP that was seen at 2 years remained at 5 years. Long-term POP failure rates after SCP are low and not affected by concomitant TOT.
