Abstract
Robotics are recently introduced to urology, with few reports
comparing robotic assisted radical cystectomy to its open counter part.
We undertook this comparison of ORC and RARC to determine
whether surgical approach affects perioperative and pathological
outcomes.
Methods:
We studied 147 consecutive patients who underwent RARC
(34) or ORC (113) for bladder cancer between December 2007 and
July 2009. RARC cases were done using da Vinci S robot and urinary
diversion was done through mini laparotomy. Data was collected
prospectively. Characteristics of the RARC and ORC groups were
compared using Wilcoxon and Fisher’s exact tests. Multivariate
models were developed to for blood loss (linear regression) and
transfusion (logistic regression), controlling for age, sex, preoperative
hematocrit, presence of extravesical disease, lymph nodes status and
operative time.
