Laparoscopic radical cystectomy with continent urinary diversion (rectosigmoid pouch) performed completely intracorporeally: an intermediate functional and oncologic analysis.

Objectives: To present our experience with the first series of rectosigmoid pouch creation performed completely laparoscopically for continent urinary diversion after radical cystectomy to treat transitional cell carcinoma of the bladder. We evaluated the intermediate functional and oncologic outcomes.

Methods: Between April 2000 and January 2004, 20 patients underwent laparoscopic radical cystectomy with urinary diversion for transitional cell carcinoma at the Department of Urology, Charite Hospital, Campus Mitte. Of the 20 patients, 12 received a rectosigmoid pouch for urinary diversion. The procedures were performed completely laparoscopically, including free-hand laparoscopic suturing and in situ knot tying techniques. The mobilized specimens were removed in an endoscopy bag by way of the rectum or vagina.

Results: All operations were completed laparoscopically by two surgeons without conversion to open surgery. The median operating time was 485 minutes. One patient needed a blood transfusion of 2 U. All specimens had negative surgical margins. Two patients required reoperation. The median follow-up was 33 months. All patients were continent during the day, and 11 patients were continent at night. One patient developed unilateral hydronephrosis with loss of kidney function. No patient developed local recurrence, but 3 patients had systemic progression. Two of the three died of metastatic disease.

Conclusions: This is the first series of laparoscopic radical cystectomy using an intracorporeal rectosigmoid pouch. Our functional data for continence and upper urinary tract obstruction were comparable with those of open rectosigmoid pouch studies. We were able to demonstrate an oncologic outcome similar to that achieved by the open surgical approach.
