Scintigraphic appearance of polycystic kidney disease

Patients aged 12 to 62 with polycystic kidney disease were examined. Of these, 36 were examined while primary diagnosis was established; 42 patients were observed during treatment. Renoscintigraphy with 131I-hippuran and sup(99m)Tc-DTPA angionephroscintigraphy with sup(99m)Tc-dimercaptosuccinic acid, sup(99m)Tc-tin-gluconate, sup(99m)Tc-cyton and nephroscintigraphy with 107Hg-neohydrine were used. Renoscintigraphy was used to evaluate renal excretory function. Based on angionephroscintigraphy 3 degrees of renal lesion were singled out: mild (43.2% of the cases), moderate (24.3%) and severe (32.5%). In renoscintigraphy moderately expressed unilateral changes prevailed in 49.4% of the cases, pronounced unilateral changes in 8.6%, moderate bilateral changes in 31.3% and demonstrable bilateral changes in 6.5%. In 4.2% of the cases no changes were found on the computerized renograms. The diagnostic value of re.no- and angionephroscintigraphy in polycystic kidney disease was 92.6%. The study has shown a high efficacy of radionuclide methods in the evaluation of the process over time, therapeutic results and the elucidation of the familial nature of the disease
