[Radionuclide studies of congenital kidney abnormalities]

Using the potentialities of isotope nephrograms as a screening test a total of 4746 patients suspected of renal abnormalities were examined. The author established pathological deviations in 561 cases (11.8%). During further verification using scintigraphy unsuspected congenital renal abnormalities (aplasia, hypoplasia, dystopia, double kidney, horseshoe kidney, solitary cyst and polycystic renal disease) were found in 46 patients (8.2%). The diagnosis was confirmed at subsequent venous x-ray urography. A conclusion has been made as to the role of comprehensive nephrographic-scintigraphic examination in the diagnosis of congenital renal abnormalities.
