A new modified renal vein anastomosis in unilateral dual renal transplantation

Transplantation of renal allografts inadequate to meet the recipient's metabolic needs has been proposed as a cause of chronic allograft failure. Dual renal transplant is a novel idea to transplant enough nephron mass to solve this problem. According to the current literature, graft renal veins are anastomosed to the external iliac vein or inferior vena cava as venous drainage in the setting of dual renal transplantation. In the presented case, renal blood was returned through one of the grafts back to the systematic circulation through the other renal vein graft. This provides a feasible option for unilateral dual renal transplantation to accomplish renal vein anastomosis in some difficult situations.
