Is right-sided laparoendoscopic single-site donor nephrectomy feasible?

Abstract

Objective: To present our initial experience with right-sided laparoendoscopic single-site donor nephrectomy (LESS-RDN). Laparoendoscopic single-site (LESS) donor nephrectomy, although in its infancy, represents a potential exciting advancement over conventional laparoscopic donor nephrectomy (LDN). Almost all of the reported cases thus far have been left-sided kidneys.

Methods: Between August 2009 and June 2010, a total of 85 consecutive LESS DN were performed. Of these, 6 (7%) were LESS-RDN. Donor outcomes analyzed included operative time, estimated blood loss, complications, visual analog pain scores, and recovery time. Renal vein lengths were measured on preoperative computed tomography scans. Recipient outcomes analyzed included recipient creatinine at discharge and at 1 and 3 months. All data were prospectively accrued in an institutional review board-approved database.

Results: Five LESS-RDN were successfully performed. One case was converted to hand-assisted laparoscopy to optimize hilar dissection. The mean (± SE) operative time until allograft extraction was 89 ± 5.1 minutes, total operative time was 146 ± 12.8 minutes, warm ischemia time was 3.9 ± 0.2 minutes, and estimated blood loss was 92 ± 27 mL. The mean renal vein length was 2.7 ± 0.3 cm. There were no perioperative complications. All allografts functioned after transplantation. When compared with a matched cohort of LESS-LDN, there was no difference in allograft function at discharge and at 1 and 3 months.

Conclusions: Although technically challenging, LESS-RDN in experienced hands can be performed safely and should be considered as an alternative if it is the preferred kidney for transplantation.
