Robotic-assisted laparoscopic radical cystectomy: surgical and oncological outcomes

Abstract

PURPOSE: Our first 91 consecutive cases undergoing a robotic assisted cystectomy were analyzed regarding perioperative outcomes, pathological stages and surgical complications. MATERIALS AND METHODS: Between 2007 and 2010 a total of 91 patients (76 male and 15 female), 86 with clinically localized bladder cancer and 5 with non-urothelial tumors underwent a radical robotic assisted cystectomy. We analyzed the perioperative factors, length of hospital stay, pathological outcomes and complication rates. RESULTS: Mean age was 65.6 years (range 28 to 82). Among the 91 patients, 68 were submitted to an ileal conduit and 23 to a neobladder procedure for urinary diversion. Mean operating time was 412 min (range: 243-618 min) and mean blood loss was 294 mL (range: 50-2000 mL). In 29 % of the cases with urothelial carcinoma the T-stage was pT1 or less, 38 % were pT2; 26 % and 7 % were classified as pT3 and pT4, respectively. 14 % of cases had lymph node positive disease. Mean number of lymph nodes removed was 15 (range 4 to 33). Positive surgical margins occurred in 2 cases (2.1 %). Mean days to flatus were 2.13, bowel movement 2.88 and inpatient stay 18.8 (range: 10-33). There were 45 postoperative complications with 11 % major (Clavien grade 3 or higher). At a mean follow-up of 15 months 10 patients had disease recurrence and 6 died of the disease. CONCLUSIONS: Our experience demonstrates that robotic assisted radical cystectomies for the treatment of bladder cancers seems to be very promising regarding surgical and oncological outcomes.
