Abstract

OBJECTIVES:

We describe a novel method of ensuring posterior approximation and preventing urinary leak during the running anastomosis of robotically assisted laparoscopic prostatectomy.

METHODS:

Two 3-0 Monocryl RB-1 sutures are tied end-to-end. The undyed suture is placed first at the 5-o'clock position on the bladder side outside-in and then through the urethra at the same location inside-out. Proceeding clockwise, the suture is placed twice more through both the bladder and the urethra. With gentle manipulation, the suture is cinched down to provide secure posterior approximation; however, if tension is released from the suture coming from the urethra, the approximation may loosen and could result in a potential "gap" and site for anastomotic leakage. To prevent potential loosening, tension is maintained on the stitch as a single Lapra-Ty is placed at the base of the suture as it leaves the urethra. When the tension is released, the posterior approximation is tightly maintained and the remaining anastomosis is completed.

RESULTS:

We have performed 110 robotically assisted laparoscopic prostatectomies. Six urinary leaks requiring prolonged catheterization were identified in our first 90 patients (6.7%). We have not experienced any urinary leakage or short-term complications in the subsequent 20 patients using this technique.

CONCLUSIONS:

We describe a novel technique to ensure secure posterior approximation during the vesicourethral anastomosis after robotically assisted laparoscopic prostatectomy. A single Lapra-Ty clip placed early during the anastomosis prevents potential "gaps" in the approximation that may be the source of troublesome leakage.
