Laparoscopic radical cystectomy with intracorporeal creation of a continent urinary diversion. Future or present?

Abstract

Once laparoscopic radical prostatectomy has been mastered, the step to performing a radical cystectomy is not that far. The challenge is to create the urinary diversion by laparoscopy. In this report we describe our experience with 11 laparoscopic radical cystectomies and intracorporeal construction of a continent urinary diversion (Mainz pouch II) as a treatment option in patients with muscle-invading bladder cancer. All 11 procedures could be performed successfully. A conversion to open surgery was not required in any case. The mean surgery time was 6.7 h. Except for two pouch fistulas we did not observe any intra- or postoperative complications. The functional as well as the oncological results are convincing. Less morbidity and faster recovery are the main advantages of this minimally invasive procedure. In addition, the low levels of blood loss, fluid shifts, and electrolyte loss considerably reduce cardiovascular stress. Radical cystectomy and construction of a continent urinary diversion represent the limit of technically feasible laparoscopy and should be done exclusively in specialized centers.
