Retroperitoneoscopic Donor Nephrectomy on the Right Side Provides Equivalent Outcomes and Donor Safety to That on the Left Side.

BACKGROUND: The left kidney is typically selected for laparoscopic donor nephrectomy. In contrast, right kidney donation raises concerns for donor safety, and venous anastomosis may be difficult to achieve due to the short renal vein. We investigated the safety and operative outcomes of right donor nephrectomy compared with those of the left. METHODS: We retrospectively analyzed the clinical records of living donor-kidney transplant donors and evaluated operative outcomes such as operative time, ischemic time, blood loss, and surgical complications in the donor. RESULTS: We identified 79 donors (left:right = 62:17 cases) between May 2020 and March 2023. There were no significant differences between the 2 groups regarding age, sex, body mass index, and number of renal arteries. Although the operative time (left and right: 190 and 225 minutes, excluding waiting time; P = .009) and warm ischemic time (left and right: 143 and 193 seconds, P = .021) were significantly longer on the right side, the total ischemic time (82 and 86 minutes, P = .463) and blood loss (left and right: 35 and 25 mL, P = .159) were comparable between the groups. There were no significant differences between the groups regarding the surgical complications. CONCLUSIONS: Operative outcomes were similar in both donor sides in the retroperitoneoscopic donor nephrectomies. The right side should be considered for donation in this operative procedure.
