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).
