Post-kidney Transplant Robot-assisted Laparoscopic Ureteral (Donor-receiver) Anastomosis for Kidney Graft Reflux or Stricture Disease.

OBJECTIVE

To report our experience with robot-assisted ureteral anastomosis for kidney graft. Kidney graft complex ureteral strictures or symptomatic vesicoureteral reflux may require complex reconstruction. This is classically done through an open surgical access, which adds to the morbidity of kidney transplantation. The da Vinci robot enables performance of complex laparoscopic procedures and may hence be used for such reconstructions.

PATIENTS AND

METHODS

We retrospectively reviewed all patients undergoing robotic surgical revision for stricture or reflux disease over a 3-year period. Contemporary patients who underwent open surgery were used as a control group.

RESULTS

Ten patients underwent a robotic attempt, of whom 4 needed conversion to open surgery. Seven patients underwent an open surgery. Preoperative demographics were similar in both groups. The median operative time was 293 minutes, with a shorter operative time in the open group. The group of patients who could be completed robotically had a significantly lower postoperative length of stay (5 vs 9 days), quicker return to normal food intake (postoperative day 1 vs 3), and quicker control of pain without opiates (postoperative day 1 vs 4) than the converted or open group. Morbidity was comparable with 1 late Clavien IIIb complication in each subgroup (open, converted, and robotic group). After a median follow-up of 43 months, renal function was stable and there were no recurrent graft infections.

CONCLUSION

Robotic ureteral reconstruction for kidney graft patients is feasible and efficient, and offers the classical advantages of minimally invasive surgery with outcomes comparable with open series.
