Importance:
The retropubic midurethral sling (rMUS) and sacrocolpopexy are treatments for stress urinary incontinence (SUI) and pelvic organ prolapse, respectively, which are often performed concomitantly.
Objective:
The purpose of this study was to identify whether a difference exists in the failure rates of rMUS when placed alone or at the time of robotic sacrocolpopexy (RSC).
Study Design:
We conducted a single-center retrospective cohort study of patients who underwent rMUS placement between December 2015 and March 2020. The primary outcome was rMUS failure defined as additional treatment for SUI at any point.
Results:
There were 160 patients who underwent isolated rMUS and 175 patients who underwent rMUS and RSC. Patients who underwent isolated rMUS were more likely to be obese (P < 0.01). Patients who underwent RSC were older (63.3 ± 9.9 vs 57.7 ± 13.7 years, P < 0.0001) and more likely to be White (P = 0.02). Follow-up ranged from 0 to 46 months (median, 3 months; interquartile range, 3 months). Failure was observed in 2.3% of rMUS placed alone and 8.6% of rMUS with RSC. Patients who underwent rMUS and RSC had an odds ratio of 3.63 for rMUS failure (P = 0.03; 95% confidence interval, 1.16-11.38). Hypertension was associated with 4 times higher rMUS failure (odds ratio, 4.18; P = 0.02; 95% confidence interval, 1.29-13.58).
Conclusions:
We observed a significantly increased rate of rMUS failure from those placed alone to those placed at the time of RSC. Retropubic midurethral sling at the time of RSC was 4 times more likely to result in additional SUI treatment.
