Initial Experiences with Robot-Assisted Laparoscopic Radical Cystectomy

PURPOSE Robot-assisted laparoscopic radical cystectomy (RLRC) is a new option for the treatment of muscle-invasive bladder cancer, and case series for RLRC have been increasing recently. We report our operative technique and initial experiences with RLRC with extracorporeal urinary diversion. MATERIALS AND METHODS Between October 2008 and November 2009, 17 consecutive patients with muscle-invasive bladder cancer underwent RLRC, pelvic lymph node dissection, and extracorporeal urinary diversion. Urinary diversion included 13 ileal conduits and 4 orthotopic neobladders (Studer method). Data were collected prospectively on patient demographics, intraoperative parameters, pathologic staging, and postoperative outcomes. RESULTS The mean patient age was 63.7 years. The mean body mass index was 22.6 kg/m(2). No patients had a history of previous abdominal surgery. The mean operative time was 379.1 minutes, including 32.6 minutes for pelvic lymph node dissection, 185.2 minutes for RLRC, and 159.4 minutes for urinary diversion. The mean estimated blood loss was 210.5 ml. The mean hospital stay was 20.7 days and the mean time to oral intake and ambulation was 5.0 and 1.3 days, respectively. There were no major perioperative complications. The pathologic reports showed urothelial cell carcinomas in all cases. CONCLUSIONS Our initial clinical experiences indicate that RLRC with pelvic lymph node dissection and extracorporeal urinary diversion is a safe and feasible procedure with minimal blood loss and rapid recovery. Long-term follow up in a larger patient population is needed to determine the true oncological and functional benefit of this procedure.
