Abstract

We retrospectively analyzed the morbidity and risk factors of bladder neck contraction (BNC) after retropubic prostatectomy. Of 99 consecutive patients who underwent radical retropubic prostatectomy between 1995 and 2001, 10 (10%) developed anastomotic stricture after surgery. BNC was diagnosed 7 months on average after the surgery. Nine patients were successfully treated by cold-knife incision, but 5 required additional incision against the recurrence of BNC. None of them revealed newly diagnosed stricture or incontinence. Thirteen potential risk factors including age, stage, PSA, neoadjuvant treatment, pathology, intraoperative blood loss, operation time, operator, nerve sparing, extravasation of urine, marginal status, the year of operation, and the method of ureterovesical anastomosis were evaluated using univariate and multivariate analysis. The BNC rate was increased in patients with longer (more than 4 hrs) operations and excessive bleeding (more than 1,000 ml) (p=0.0027, respectively). The year of operation (before 1998, p=0.0015), the method of ureterovesical anastomosis (p=0.0017), operator experience (less than 5 cases, p=0.0056), and neoadjuvant treatment (p=0.09) were also risk factors. In multivariate analysis, the year of operation (p=0.03) and operator experience (p=0.04) were strong predictors of BNC. The skill levels of surgeons and institutes are expected to decrease BNC.
