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

Objective To identify risk factors for postoperative stress urinary incontinence ( POSUI ) after native‐tissue prolapse repair without a concomitant anti‐incontinence procedure. Methods 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. Results 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 cm H 2 O (odds ratio 2.93), and urodynamically diagnosed SUI (odds ratio 2.26) were independent risk factors for POSUI . Conclusion 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.
