The prevalence of voiding difficulty after TVT,its impact on quality of life,and related risk factors

Objective: To determine the prevalence of voiding difficulty (VD), quality of life, and related risk factors after tension-free vaginal tape (TVT). Design: Prospective cohort study in 703 women with a TVT procedure for stress urinary incontinence. Main outcome measures: VD stated by women, Urogenital Distress Inventory (UDI-6) question 5 (difficulty in emptying the bladder), maximum flow rate, postvoid residual urine, necessity of postoperative catheterization, tape division, and impact on quality of life (Incontinence Impact Questionnaire, IIQ-7). Results: Postoperative catheterization (>24 h) was necessary in 11% and tape division in 1.3% of patients. There were 26% of women who stated VD and 25% reported moderate to great impairment on the UDI-6 after 36 months. While the negative impact on the outcome of TVT in women with abnormal voiding compared to women without is higher, the impact decreased significantly after TVT, implying a considerable improvement in quality of life. Pre-operative existing voiding difficulty and concomitant prolapse surgery were independent risk factors. Conclusions: Symptoms of VD occurred after TVT and caused lesser improvement in quality of life.
