Technique for laparoscopic running urethrovesical anastomosis:the single knot method.

Objectives: To describe a technique for facilitating the urethrovesical anastomosis at the time of laparoscopic radical prostatectomy.

Methods: Two 6-in. polyglycolic acid sutures (one dyed, one white) are tied together at their tail ends and delivered into the operative field by way of a 12-mm port. A running suture is completed from the 6:30 to the 12:00-o'clock position and from the 5:30 to the 12:00-o'clock position, at the end of which a single intracorporeal tie is completed. The catheter is placed before completing the anterior row of sutures; the catheter is left in place for 5 to 7 days.

Results: This anastomotic technique has been used in 122 laparoscopic radical prostatectomies and 8 robot-assisted laparoscopic radical prostatectomies. The average time for the anastomosis was 35 minutes (range 14 to 80). All anastomoses were watertight. No symptomatic postoperative urinary leaks have occurred, and no clinically evident clinical bladder neck contractures resulted.

Conclusions: We describe a simple, watertight, running laparoscopic suture technique for accomplishing the urethrovesical anastomosis during laparoscopic radical prostatectomy.
