Robotic-assisted laparoscopy living donor nephrectomy: Technique and results of a monocentric retrospective series.

INTRODUCTION

Robot-assisted nephrectomy for living kidney donation (LKD) has been described in the literature as a safe and reproducible technique in high volume centers with extensive robotic surgery experience. Any surgical procedure in a healthy individual ought to be safe in regards to complications. The objective of this study was to evaluate the Robotic-assisted Living Donor Nephrectomy (RLDN) experience in a robotic surgery expert center.

METHODS

This is a retrospective study from 11/2011 and 12/2019. In total, 118 consecutive Living Donor (LD) kidney transplants were performed at our institution. All the procedures were performed by robotic-assisted laparoscopic approach. Extraction was performed by iliac (IE), vaginal (VE) or umbilical extraction (UE). The left kidney was preferred even if the vascular anatomy was not modal.

RESULTS

For donors: the median operative time was 120min with 50mL of blood loss. The median warm ischemia time was 4min, with a non-significant shorter duration with the UE (4min) in comparison with IE or VE (5min). Nine patients had postoperative complications including 1 grade II (blood transfusion) and 1 grade IIIb (vaginal bleeding after VE). None of our procedures were converted to open surgeries and no deaths were reported. For the recipients: 1.7% presented delayed graft function; their median GFR at 1 year was 61mL/min/1.73m2.

CONCLUSION

RLDN in an expert center appears to be a safe technique. The advantages of the robot device in terms of ergonomy don't hamper the surgical outcomes. Donor, recipient and graft survivals seem comparable to the reported laparoscopic outcomes in the literature.
