Risk factors for stress urinary incontinence after native-tissue vaginal repair of pelvic organ prolapse

To identify risk factors for postoperative stress urinary incontinence (POSUI) after native-tissue prolapse repair without a concomitant anti-incontinence procedure.

The present single-center retrospective study included women with genital prolapse who underwent high uterosacral ligament suspension without a concomitant anti-incontinence procedure during 2008-2013. Univariate and multivariate analyses were performed to identify risk factors for POSUI (identified through clinical interview and International Consultation on Incontinence Modular Questionnaire-Short Form [ICIQ-SF] self-administration) at 6 months.

In total, 87 (20.9%) of 417 women developed POSUI. Preoperative stress urinary incontinence (SUI) and urodynamically diagnosed SUI were significantly associated with POSUI; moreover, women with POSUI had a higher preoperative ICIQ-SF score, a lower opening detrusor pressure, and a lower detrusor pressure at maximum flow than did women without POSUI (P<0.05 for all comparisons). In the multivariate analysis, preoperative SUI (odds ratio 3.11), a detrusor pressure at maximum flow of less than 30 cmH2 O (odds ratio 2.93), and urodynamically diagnosed SUI (odds ratio 2.26) were independent risk factors for POSUI.

Preoperative urodynamic parameters, obtained before prolapse repair surgery, were associated with POSUI and could be useful in providing adequate counseling to facilitate decision making on whether to add a concomitant anti-incontinence procedure.
