title: Robot-assisted radical cystectomy and pelvic lymph node dissection: initial experience at Roswell Park Cancer Institute.
abstract: OBJECTIVE
  One series of robot-assisted radical cystectomy with pelvic lymph node dissection has been reported. We report our operative technique and initial experience.
  
  
  METHODS
  Twenty consecutive patients underwent robot-assisted radical cystectomy, pelvic lymph node dissection, and open urinary diversion for operable bladder cancer from October 2005 to June 2006. Data were collected prospectively on patient demographics, intraoperative parameters, pathologic staging, and postoperative outcomes.
  
  
  RESULTS
  The mean patient age was 70 years (range 56 to 90). The mean body mass index was 26 kg/m2 (range 17.3 to 36). Fourteen patients had undergone previous abdominal surgery. The mean operative time was 197 minutes for robot-assisted radical cystectomy, 44 minutes for pelvic lymph node dissection, and 133 minutes for urinary diversion. The mean blood loss was 555 mL. One case was converted to an open procedure because of the patient's inability to tolerate the Trendelenburg position. The mean hospital stay was 10 days. Two patients had major complications. One patient had positive vaginal margins and 9 of 26 nodes were positive. Four patients had incidental prostate cancer. The mean time to the return to nonstrenuous activity was 4 weeks and to strenuous activity was 10 weeks.
  
  
  CONCLUSIONS
  Robot-assisted radical cystectomy and pelvic lymph node dissection can be performed safely in patients who are considered candidates for open cystectomy. Long-term oncologic control data and functional outcomes are needed to assess the true benefits of robot-assisted radical cystectomy.
