Objectives: To evaluate the necessity and clinical effect of posturethroplasty imaging. Methods: We reviewed our database of all urethroplasties performed by a single surgeon at our referral center during a 2-year period. The patients underwent voiding cystourethrography at a mean of 24 days postoperatively. The data analyzed included patient history and demographics, operative details, imaging results, and clinical outcomes. Results: From 2007 to 2009, 210 patients underwent urethral reconstruction at our center. The patients undergoing meatoplasty or staged repairs were excluded, leaving 156 patients with postoperative imaging studies for analysis. Of 110 anterior urethroplasties, 59 (54%) consisted of excision and primary anastomosis, 28 (25%) an augmented anastomotic procedure, and 23 (21%) a pure ventral onlay with a flap or graft. All 46 posterior urethroplasties were performed with scar excision and primary anastomosis. Of the 156 patients, only 4 (3%) had extravasation on postoperative voiding cystourethrography (2 after posterior urethroplasty, 1 after augmented anastomosis, and 1 after ventral onlay)all were successfully managed with catheter replacement and removal at a mean of 8 days afterward. None of the 59 men undergoing excision and primary anastomosis demonstrated extravasation. Conclusions: Extravasation on posturethroplasty voiding cystourethrography is rare after approximately 3 weeks of catheter drainage. Imaging can be omitted after uncomplicated excision and primary anastomosis urethroplasty.
