SCINTIPHOTOGRAPHY IN DIAGNOSIS OF URINARY FISTULA AFTER RENAL TRANSPLANTATION

Scintiphotographic studies in six patients with ureteral fistula following renal transplantation are presented. Images were obtained using ssmTc Sn-DTPA or 1311-orthoiodohippurate. Urinary leakage was accurately detected in each case but the pattern of extravasation is highly variable. When carefully performed, radionuclide scm tiphotography is a safe and effective method for detecting urinary leakage after renal transpian tation.
