Introduction and hypothesis: The aim of this study is to investigate the risk factors of voiding dysfunction occurring within 1 month after surgical treatment of urinary incontinence.
Methods: Medical records of 903 women who underwent anti-incontinence surgery at Yonsei Medical Health System from January 1999 to April 2007 were reviewed. The patient demographics, urodynamic parameters, pelvic organ prolapse stage, surgical procedures, and concomitant surgery were retrospectively evaluated. Postoperative voiding dysfunction was defined as post-void residual urine measuring greater than 100 cc at two or more successive trials.
Results: Age, menopausal status, maximum flow rate, average flow rate, post-void residual, anti-incontinence surgery type, stage of pelvic organ prolapse, and concomitant prolapse surgery were associated predictors of voiding dysfunction after anti-incontinence surgery. In multivariate analysis, concomitant anterior colporrhaphy (OR 2.4; 95% CI 1.38-4.11) was the only independent risk factor.
Conclusions: The most important risk factor associated with voiding dysfunction was concomitant anterior colporrhaphy.
