Analysis of the impact of obesity on recurrence rates of stress urinary incontinence after urethrolysis or sling revision

Objective: The impact of obesity on the recurrence rates of stress urinary incontinence (SUI) after urethrolysis/sling revision was analyzed. Study Design: A retrospective analysis was conducted of patients who underwent urethrolysis or sling revision from January 2004 to November 2010. Results: Data from 74 patients were included. The mean body mass index (BMI) was 29.8 kg/m2 (SD, 6.3) and 37/74 (50%) women were obese (BMI Q 30 kg/m2) with a mean length of follow-up of 27 weeks (range, 6Y132 weeks). The following urethrolysis/sling revision surgical techniques were varied: partial transvaginal urethrolysis, complete transvaginal urethrolysis, abdominal urethrolysis, sling transection, and transvaginal sling stretching. Of the 74 cases, 25 (33.8%) had recurrent SUI after urethrolysis or sling revision. The BMI did not differ between those who did and did not have a recurrence (t test P = 0.68); 25/49 (51%) women who did not have a recurrence were obese and 12/25 (48%) women with recurrence were obese. Conclusions: Obesity was not associated with increased rates of SUI recurrence after urethrolysis/sling revision.
