Short-Term Urinary Retention After Tension-Free Vaginal Tape Midurethral Sling Performed Alone or as a Concomitant Procedure

Objective The objective was to determine whether a difference exists in short-term urinary retention after tension-free vaginal tape (TVT) midurethral sling placement when performed alone compared with when placed during a concomitant prolapse procedure. Methods We conducted a single-center retrospective cohort study that compared TVT procedures performed alone (group 1) to those with a concomitant prolapse procedure (group 2). The primary outcome was the proportion of patients discharged with an indwelling Foley catheter after failing postoperative voiding trial. Results There were 100 women in group 1 and 267 women in group 2. Concomitant prolapse procedures included vaginal approach (n = 47), robotic (n = 218), or both (n = 2). Forty-nine patients (13.4%) failed the initial voiding trial and 21 patients (5.7%) were discharged with an indwelling Foley catheter. The rate of short-term urinary retention requiring an indwelling catheter at discharge was not significantly different between group 1 and group 2 (9 [9.0%] vs 12 [4.5%], P = 0.1). The duration of catheterization after discharge was shorter in group 1 compared with group 2 (2.1 +/- 1.1 vs 4.3 +/- 2.0 days, P = 0.008). In multivariate analysis, patients discharged with a catheter were more likely to have diabetes with an odds ratio of 3.1 (95th confidence interval, 1.2-8.1). Conclusions The proportion of patients discharged with an indwelling catheter did not significantly differ if TVT was performed alone or at the time of a concomitant prolapse procedure (9.0% vs 4.5%, P = 0.1).
