The problems deriving from the anatomic differences between the two harvested kidneys make the bench surgery necessary to solve some technical difficulties in transplantation. This condition is particularly real in the case of right kidney transplantation, especially in presence of arterial anomalies. In this study, we focused our attention on venous reconstruction in cases of short renal right veins. In 3 years, we performed 55 consecutive cadaveric renal transplants in patients with an end-stage chronic renal insufficiency. The right kidney was used in 30 patients, eight of whom had two or more arteries attached to a single aortic patch, and 22 had a single artery. In these right transplanted kidneys, the elongation of renal vein was performed end-to-side to the external iliac vein, reconstructing a "T-patch" (angular reconstruction) in 28 patients and a "linear" one in two cases. The vascular anastomoses had no thrombotic problems. We have followed the progress of the patients for more than 2 years; no one has lost the graft due to chronic rejection or other complications. In conclusion, elongation of the right renal vein with a T-patch constitutes a feasible, physiological procedure without vascular complications or apparent reverberations for graft blood flow.
