Reoperation for urinary incontinence.

Abstract

The objective of the study was to describe the rate and associated factors of reoperation for urinary incontinence. A cohort study using Washington state hospitalization records from 1987 to 2005 of inpatient urinary incontinence surgeries. The cumulative reoperation rate was estimated for the entire cohort and by procedure. Cox regression was used to estimate the hazard of reoperation. A total of 41,705 women underwent either a sling or retropubic colposuspension (Burch); 1895 underwent reoperation for urinary incontinence (8.6%; 95% confidence interval, 7.8-9.5%), a rate of 5.5 per 1000 woman-years. Women undergoing Burch had a lower reoperation rate than those undergoing slings (4.2 vs 6.7 per 1000 woman-years; P < .001). Concomitant hysterectomy was associated with a lower reoperation rate for Burch and sling repairs (5.4-2.9 and 7.7-4.2 per 1000 woman-years). Reoperation for urinary incontinence occurs commonly in the general population. The variable reoperation rate observed should be further investigated, given current trends toward increased Sling use.
