Three-legged pair of pants anastomosis: a rare technique for renal transplantation

Because of the shortage of donors, kidneys previously judged to be unsuitable are now accepted for transplantation. Successful engraftment of kidneys with multiple renal arteries is one of the challenges and requires meticulous vascular surgical technique. In one of our case of renal allograft with three renal arteries, we created a single lumen by suturing three arteries together, like a three-legged pair of pants. The end of the single lumen was anastomesed to the side of external iliac artery. There was brisk diuresis on table after transplantation. Postoperatively, the patient had an uneventful course and normal graft function.
