Continuous suture of a single absorbable suture: a new simplified vesicourethral anastomosis technique in laparoscopic radical prostatectomy.

The purpose of this study was to describe a new simplified technique for facilitating vesicourethral anastomosis in laparoscopic radical prostatectomy. After prostate removal, an approximately 15-cm-long absorbable suture with one three-eighths arc needle is passed from the outside in on the full thickness of the bladder neck at the 9 o'clock position and then from inside out on the full thickness of the urethra at the 9 o'clock position. It is knotted with the suture tail. Subsequently, a continuous suture is completed between the bladder neck and urethra. A 20-French silastic catheter is placed into the bladder before completing the anterior row of sutures. Three hundred twelve consecutive patients with localized prostate cancer who had undergone the new simplified vesicourethral anastomosis were included in this retrospective study. The average time of anastomosis was 10.5 minutes (range, 8-30 minutes), as recorded for an experienced laparoscopic surgeon. The incidence rate was 2.2% for urine leakage and 1.3% for bladder neck stenosis, and the continence rate was 86.9% at 1 month, 93.3% at 3 months, 98.1% at 6 months, and 98.7% at 1 year. We present a new simplified method for vesicourethral anastomosis. The method takes little operating time and is easy for novice laparoscopists to master. Moreover, this technique has low rates of urinary leakage and bladder neck stricture.
