Robot‐assisted kidney transplantation: update from the European Robotic Urology Section (ERUS) series

Abstract

Objective To report the results of the robot‐assisted kidney transplantation (RAKT) experience performed in 10 European centres by members of the European Robotic Urology Section (ERUS)‐RAKT group. Patients and Methods This is a multicentre prospective observational study of RAKT. Descriptive analysis of recipients and donor characteristics, surgical data, intraoperative outcomes, complications rate and functional results were collected and analysed. Results Between July 2015 and September 2019, 291 living‐donor RAKTs were performed. Recipients were mostly male (189 [65%]), the mean Standard deviation ( sd) age was 45.2 (13.35) years, the mean ( sd) body mass index was 27.13 (19.28) kg/m 2 , and RAKT was pre‐emptive in 155 (53.8%) cases. Right and multiple arteries kidneys were used in 15.4%. The mean ( sd) total surgical and re‐warming time was 244 (70.5) min and 53.16 (15.27) min, respectively. In all, 17 patients presented with postoperative bleeding (5.7%). Five kidneys had delayed graft function; five (2%) were lost due to thrombosis and one due to acute rejection. Two patients had arterial stenosis, three had incisional hernias, six had ureteric stenosis, and nine had lymphoceles. Neither surgical nor re‐warming times were correlated with postoperative serum creatinine levels ( P > 0.05). Comparison of surgical data between the first 120 cases and the following 171 cases showed a significantly shorter total surgical time in the second group (265 vs 230 min, P = 0.005). Conclusions This is the largest European multicentre study of RAKT with good surgical and functional results competitive with open kidney transplant series, with a relatively short learning curve when performed in centres with a wide experience in open kidney transplantation and robotic surgery.
