Robotic-assisted laparoscopic radical cystectomy: surgical and oncological outcomes.

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.
