Abstract

The association between baseline functional status and urinary continence recovery after radical prostatectomy remains controversial. We tested the hypothesis that baseline erectile and urinary function predicts urinary continence recovery after bilateral nerve sparing radical prostatectomy. The study included 752 patients with prostate cancer treated with bilateral nerve sparing radical prostatectomy between 2003 and 2009. All patients had preoperative functional and oncological data available, including age at surgery, body mass index, prostate specific antigen, and erectile and urinary function. Preoperatively erectile and urinary function was assessed by the erectile function domain of the International Index of Erectile Function and the International Prostatic Symptoms Score. Urinary continence was defined as wearing no pads. Univariate and multivariate Cox regression models were used to test the association between predictors and urinary continence recovery after surgery. At a mean postoperative followup of 30.7 months (median 29, range 1 to 80) 611 patients (81.3%) had recovered urinary continence. Overall the urinary continence recovery rate at 1 and 3 years was 73.9% and 82.2%, respectively. On univariate Cox regression analysis patient age and the preoperative score on the erectile function domain of the International Index of Erectile Function were significantly associated with urinary continence recovery (each p ≤0.04). On multivariate analysis age at surgery and the preoperative erectile function domain of the International Index of Erectile Function were the only independent predictors of urinary continence recovery after bilateral nerve sparing radical prostatectomy (each p ≤0.04). Age and preoperative erectile function should be considered for urinary continence predictions after bilateral nerve sparing radical prostatectomy and for accurate patient counseling before surgery. Preoperative erectile function might be a marker of pelvic vascular disease, which may affect the status of the external urinary sphincter.
