Is Robot-assisted Radical Cystectomy the Preferred Minimal Invasive Procedure for Non-advanced Bladder Urothelial Carcinoma(T1-T2N0M0)? A Single Center Retrospective Study.

Background: To investigate the perioperative efficacy and cost of robot-assisted radical cystectomy(RARC) and laparoscopic RC(LRC) in patients with non-advanced bladder urothelial carcinoma Methods: : 156 patients with non-advanced bladder urothelial carcinoma undergoing minimally invasive radical cystectomy in our center between January 2015 and April 2020 were included. Perioperative data and hospitalization expenses were extracted from our database. All analyses were performed using SPSS 23.0 software, and p < 0.05 was considered statistically significant. Results: : The proportion of male patients was 86.5%(135/156) and the median age was 65(IQR 59-71) years old. RARC had a lower PSM rate (0 vs 5.3%,P=0.051), longer median operation time(370 vs 305 min,P<0.001) and higher median hospitalization cost(20565.2 vs 15532.4$,P<0.001). There were no significant differences in intraoperative transfusion rate, anesthesia resuscitation in ICU, postoperative hospital stay, 30-d complications and postoperative treatment expenses between the two groups(P=0.815,0.715, 0.817,0.92 and 0.543,respectively.) Conclusion: Short operation time and low hospitalization costs are favorable factors for LRC, but RARC may be the preferred surgical procedure for non-advanced bladder urothelial carcinoma considering the potentially low PSM rate. Trial registration: A complete informed consent was obtained from the patient and their families before the surgery.Informed consent was signed for all patients.This study was approved by the Ethics Review Committee of the Second Xiangya Hospital of Central South University
