Efficacy of robotic renal transplantation in perioperative period

Abstract

Objective To preliminarily investigate the safety and effectiveness of robot-assisted kidney transplantation (RAKT) in the perioperative period. Methods Clinical data of 14 patients undergoing renal transplantation in our department from June 2018 to March 2022 were collected and retrospectively analyzed. They were 8 males and 6 females, and at an age of 22 to 45 years. There were 4 patients receiving robotic-assisted laparoscopic living-donor kidney transplantation (RAKT group), and 10 cases receiving open kidney transplantation (OKT group) with deceased donor kidney. Arterio-venous anastomoses (AVAs) time, length of post-operative stay, pre- and post-operative serum creatinine levels, intraoperative blood loss, and incidence of post-operative complications were retrospectively analyzed between the patients of the 2 groups. Results The surgeries went well in the 14 patients. The amount of intraoperative blood loss was 162.5±47.8 mL in the RAKT group and 245.1±68.5 mL in the OKT group(P < 0.05). The arterial anastomosis time was 32.5±6.5 min in the RAKT group and 24.3±5.3 min in the OKT group. The venous anastomosis time was 16.5±3.8 min in the RAKT group and 14.6±1.5 min in the OKT group. The blood creatinine level was 98.1±33.2 μmol/L in the RAKT group and 142.8±42.1 μmol/L in the OKT group in 7 d after surgery. The retention time of drainage tube was 10.0±1.2 d in the OKT group and 6.5±0.5 d in the RAKT group(P < 0.01). The length of stay after surgery was 13.0±2.5 d in the RAKT group and 16.3±2.1 d in the OKT group(P=0.01). Conclusion RAKT is safer than OKT in the perioperative period and causes fewer postoperative complications.
