Preoperative maximal flow rate may be a predictive factor for the outcome of tension-free vaginal tape procedure for stress urinary incontinence

This study examined factors potentially predicting on the outcome of the tension-free vaginal tape procedure for stress urinary incontinence. A total of 60 women (aged 35–71 years, mean 57) with at least follow-up of 2 years were included in the study. The tension-free vaginal tape procedure was performed under local anesthesia except in two patients. At the latest follow-up 50 (83.3%) were cured of stress urinary incontinence. Two patients had new-onset urge symptoms without urge incontinence episodes. Multivariate regression analysis showed maximal flow rate to be associated with 0.9-fold risk of the failure; no other parameters had statistical significance. Our results confirm the feasibility and safety of the tension-free vaginal tape procedure and demonstrate that preoperative low maximal flow rate may be associated with the failure of the tension-free vaginal tape procedure.
