[Robot-assisted kidney transplantation]

Abstract

Background: Robot-assisted surgery has become widely adopted in urology due to advantages in comparison with laparoscopic or open approaches. Robot-assisted living kidney transplantation is one of the most challenging procedures in urology regarding technical, but also psychological and ethical aspects, and is currently routinely performed in two German departments.

Objectives: The goal was to analyze and compare current evidence and experiences of robot-assisted living kidney transplantation in Europe and in Germany.

Materials and methods: A systematic search was performed to identify relevant publications. They were compared with latest results from two German academic centers (Halle and Homburg/Saar).

Results: In 2015, robot-assisted living kidney transplantation was performed for the first time in Europe. Since then, 8 academic centers have established this procedure. Until today, more than 180 robot-assisted kidney transplantations have been performed. Short- and mid-term results have proven to be excellent with low complication rates. Apart from 3 transplant losses because of arterial thrombosis and 5 surgical re-explorations due to hematoma, no other noteworthy complications occurred. There was only 1 lymphocele. The median blood loss was 150 ml and kidney function after 1 year was unchanged in comparison with postoperative day 30.

Conclusions: Robot-assisted living kidney transplantation is not inferior to the open approach. Even superiority is not unlikely because problematic situations such as obese patients or complex vascular anatomy can be handled safely. In particular, the development of lymphocele and wound healing disorders appear to be significantly decreased compared to conventional surgery.
