A 61-year-old man received a living-donor kidney graft for an end-stage renal disease. In the postoperative course the patient was oliguric and needed dialysis. The postoperative Doppler showed a normal peak systolic velocity and maintained parenchymal perfusion associated with a parvus tardus signal. The patient was operated and a kinked renal artery was found. To reposition the artery, the distal iliac artery was clamped, sectioned, shortened and re-anastomosed after a 90° axial rotation. This innovative technic allowed restoration of a normal flow in the parenchyma and avoided an additional clamping, cooling, ischemia and re-anastomosis/reperfusion of the graft. Postoperative diuresis immediately raised >100 ml/h and creatinine durably returned to normal values.
