Robot-Assisted Harvesting of Kidneys for Transplantation and Global Complications for the Donor.

INTRODUCTION: Robot-assisted kidney harvesting from living donors is feasible and safe. We report the results of a mono-centric experience relative to 98 consecutive robotic nephrectomies with emphasis on global donor complications.

MATERIALS AND METHODS: This is a retrospective cohort study. Donors underwent robot-assisted kidney harvesting. The preferred kidney was the left one even in the presence of vascular anomalies. In the first cases we used a robotic hand-assisted technique, then the totally robotic technique, and finally the modified totally robot-assisted technique. Postoperative complications were ranked according to the five-grade Clavien-Dindo classification.

RESULTS: Between November 2009 and November 2016, 98 living donors underwent nephrectomy. We experienced 14 complications. The 3 intraoperative ones (3.06%) were 1 pneumothorax and 2 acute bleedings, 1 of them requiring transfusion. The 11 postoperative complications (11.22%) were as follows: 5 wound seromas, 1 rhabdomyolisis (Clavien I), 1 paretic ileum, 1 anemia requiring transfusion, 1 hypertensive crisis (Clavien II), and 2 chylus collections drained by interventional radiologists (Clavien III). Transfusion rate was 2.1%; conversions, reoperations, and mortality were nil. No statistically significant difference was observed between the patients with complications and without in terms of gender, age, anatomical anomalies, body mass index (BMI), and learning curve. We observed a longer global operation length of time in patients with complications.

CONCLUSION: Robotic assistance results in shorter and simpler learning curves for the harvesting of kidneys from living donors. It enables an easier and more efficient management of possible intraoperative complications. The rate of postoperative complications is comparable with the rate of complications encountered in traditional laparoscopic series with high numbers of harvestings.
