Voiding dysfunction following suburethral tape

Abstract

Voiding dysfunction (VD) is relatively common following suburethral tape insertion. Our study aimed to identify perioperative variables that predict VD. Women who underwent suburethral tapes (TVT(TM) and TVT-O(TM)), either as sole procedure or with a concomitant prolapse repair, were studied retrospectively. The primary outcome was women requiring catheterisation and/or re-catheterisation in the postoperative period. A total of 319 women underwent suburethral tapes within the study period: 256 case notes (80.2%) were available for review and 40/256 women (15.6%) developed postoperative VD. No preoperative urinary symptoms were associated with postoperative VD. Univariate analysis demonstrated three variables associated with VD: average flow rate (Q-ave) ≤5th centile (odds ratio (OR) 2.3, 95% CI 1.2-6.5, p = 0.016), a combination of Q-ave and maximum flow rate (Q-max) ≤5th centile (OR 2.8, 95% CI 1.1-6.9, p = 0.030) and concomitant prolapse procedure (OR 3.6, 95% CI 1.5-8.9, p = 0.005). Following multivariate logistic regression Q-ave ≤5th centile and concomitant prolapse procedure showed the strongest association with VD.
