[Radionuclide evaluation of the function of the operated kidneys].

Altogether 68 patients were examined in early and late periods after operations on the kidneys. Function of the operated kidney was checked up by the results of two-indicator renal scintigraphy with 99mTc-DTPA and 131I-hippuran. When the kidney preserved its secretory capability and the suppression of organ function was caused by inhibited urine passage via the upper urinary tract, therapy aimed at the restoration of the kidney integrity and the elimination of the urine discharge obstruction, resulted in a rapid and complete recovery of all renal functions. Operative treatment of prolonged urological diseases complicated by chronic pyelonephritis, helped to accelerate secretory-excretory processes and slightly improved function of unchanged nephrons. A progressive decrease in the actively functioning parenchyma was recorded on scintigrams in 28% of the cases of the formation of the arteriosclerotic kidney. The authors found radionuclide investigations appropriate in the postoperative period not only in the development of complications and recurrences of urological diseases. Two-indicator renal scintigraphy with glomerulotropic and tubulotropic radiopharmaceuticals made it possible to give an objective assessment of the efficacy of surgical intervention.
