title: Diuretic radionuclide urography in the diagnosis of suspected ureteral obstruction following renal transplantation.
abstract: The diuretic radionuclide urogram has been shown to be an effective method to discriminate obstructive from nonobstructive hydronephrosis in nontransplanted renal units. This test was evaluated in 9 renal transplant patients with suspected partial ureteral obstruction. An obstructed pattern in 2 patients was confirmed and relieved by an operation. Nonobstructed patterns in 7 patients were verified by long-term clinical followup and subsequent ancillary testing. Accurate in all 9 cases, this investigation appears to provide a safe, noninvasive method to diagnose suspected post-transplantation ureteral obstruction.
