In more than 95% of worldwide living-donor kidney transplants(LDKT), the donor's left kidney (LK) is preferred because of technical difficulties and a shorter vein of the right kidney (RK).

We analyzed our experience regarding the laterality of the donor kidneys used for LDKT between 2012 to 2017. We compared demographic variables and perioperative parameters of the LK and RK groups. Preoperative anatomical data or renal parenchyma issues were studied to elucidate the indication of RK use.

A total of 320 LDKT were analyzed, 262 of them using LK and 58 (18.1%) RK. The main reasons for choosing RK were: multiple left arteries in 45 (77.5%) and lower volume or pathological changes in RK such as lithiasis, aneurysm, pelvic dilatation in 8 (13.8%). Distribution as to gender, age, BMI> 30, use of unrelated donor, laparoscopic or open nephrectomy, and kidney with more than 1 artery was similar between donors of RK and LK groups. The distribution of gender, age, BMI> 30, Diabetes as baseline disease, preemptive Tx, use of Double J and need for post-TX dialysis was also similar between recipients of the both groups. The 1-year patient and graft survival in the LK and RK groups, was 98.8% x 98.3% (p=0.71) and 96.5% x 94.8% (p : 0.52), respectively. The incidence of intraoperative donor complications in the LK and RK groups was respectively 3.0% x 5.1% (p=0.42) and, at the recipients, 2.3% x 6.9% (p=0.06); the donor and recipient rate of postoperative complications was 1.5% x 1.7% (p= 0.91) and 14.5% x 12.0% (p=0.62).

Our group has used RK in LKDT more frequently than the literature and reached similar outcomes as compared with the use of LK.
