Outcome of midurethral tape continence surgery in patients with and without urodynamically confirmed stress incontinence

Abstract

To compare the outcomes of midurethral tape continence surgery in patients with urodynamically confirmed stress incontinence (USI) and patients with symptoms of stress urinary incontinence but normal urodynamic studies (NUDS) and a positive 1-h pad test. Analysis of data collected prospectively from 356 women who underwent tension-free vaginal tape (TVT) surgery from June 1998 to September 2009. There were 25 women with NUDS but a positive pad test. Outcome measures in these 25 women were compared with 65 women with urodynamically confirmed stress incontinence. These 65 women were chosen as suitable controls from the group of 331 potential controls. All the women underwent TVT surgery under local or spinal anaesthesia. The outcome measures were: (1) absence of stress urinary incontinence symptoms, (2) new occurrence of lower urinary tract irritative symptoms (LUTS), (3) persistent voiding dysfunction (VD), and (4) recurrent urinary tract infections (UTIs). Following TVT, stress incontinence was absent in 100% and 97% of patients in the NUDS and USI groups respectively. The occurrence of LUTS was 4% and 4.6% in the NUDS and USI groups, while VD was found in 4% and 4.6% and recurrent UTIs in 8% and 6.1% of the groups respectively. There were no significant differences in outcomes following TVT in patients with and without urodynamically confirmed stress urinary incontinence.
