Scintigraphy of a double renal transplant from an infant donor.

Renal scintigraphy was performed to rule out a urinary leak on a 47-year-old woman a few days after she underwent pediatric cadaver kidney transplantation. Because of the chronic shortage of donor organs, paired pediatric kidneys (from donors younger than 5 years old) are increasingly transplanted using en bloc extraperitoneal anastomosis of the donor aorta and vena cava into the recipient's extemal iliac artery and vein. The transplantation of two infant kidneys into one recipient doubles the amount of functional renal mass and increases the chance of good long-term renal function. The postoperative scintigraphic evaluation did not show any abnormality.
