Renal Vein Lengthening Using Gonadal Vein Reduces Surgical Difficulty in Living-Donor Kidney Transplantation

Abstract

Background

During living-donor kidney transplantation, to maximally decrease donor injury, the right kidney with lower glomerular filtration rate often is selected as the donor kidney. However, the renal vein of the right kidney is relatively short for transplantation. The gonadal vein is essentially useless and is easily accessed during the donor nephrectomy.

Methods

Seventeen live kidney donors received right kidney nephrectomy for living-donor kidney transplantation. Short renal veins were lengthened by circular anastomosis or spiral anastomosis of longitudinally cut gonadal veins. The renal function of receivers was evaluated using creatinine clearance.

Results

The renal veins were extended by 2.0–2.7 cm with circular anastomosis and 4.1–4.5 cm with spiral anastomosis with an average of 2.5 ± 0.7 cm. Lengthening of renal veins averaged 20.4 ± 4.2 min. All surgeries were successful, significantly reducing difficulty of vascular anastomosis during transplantation. No poor early graft function occurred. No side effects were observed in donors.

Conclusions

When donor renal veins are too short for effective kidney transplantation and may affect reliability of vascular anastomosis, they can be lengthened by using gonadal veins without increasing injury to the donor. Successful extension of donor kidney renal veins expands the indication for right donor kidneys.
