Abstract:
A 19-year man underwent live related renal transplantation for end-stage renal disease. He was referred for a baseline renal scan on day 4. The urine output was satisfactory and the serum creatinine showed a decreasing trend. Renal dynamic scintigraphy with technetium-99m ethylenedicysteine demonstrated radiotracer activity above the transplant kidney, suspected to be a urine leak. Postvoiding posterior, delayed images confirmed that the radiotracer activity in the anterior postvoiding images was the result of vesicoureteral reflux from the patient's native kidneys.
