Diuretic radionuclide urography in the diagnosis of suspected ureteral obstruction following renal transplantation.
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.
