Purpose: Robot-assisted radical cystectomy (RARC) is known to have less postoperative morbidity and complications than open radical cystectomy. However, various complications not yet have been reported after RARC. In this study, we aimed to identify the predictors of complications following RARC.
Patients and methods: From August 2008 to November 2017, we retrospectively reviewed 126 patients who underwent RARC with extracorporeal urinary diversion. Overall perioperative complications were examined, and factors that may affect complications were analyzed using a logistic regression model. Complications were classified according to the Clavien-Dindo system.
Results: Overall postoperative complications occurred in 78 (61.9%) of 126 patients. Whereas the rate of minor complications was 58.0% (grade I=15.9% (n=20), grade II=42.1% (n=53)), the rate of major complications was very low (grade IIIa=1.6% (n=2), grade IIIb =2.4% (n=3)). No fatal complications more than grade IV were developed. Notably, transfusions (27.0%), urinary tract infection (15.9%), anastomosis site leakage (14.3%), and ileus (10.3%) were the most common complications after RARC. In the multivariate regression model, previous intravesical instillation (odds ration [OR]=3.374), preoperative hemoglobin (OR=0.751), and estimated blood loss (EBL) (OR=3.949) were identified as the predictors of postoperative complications.
Conclusion: In sum, our data showed the rates of major complications were comparable after RARC with extracorporeal urinary diversion compared as reported in previous studies and lower major than minor complications following RARC. Moreover, we identified the independent predictors of postoperative complications, such as preoperative hemoglobin, intravesical instillation, and EBL.
