[Radionuclide diagnosis of kidney calculi]

Radionuclide investigations were conducted in 322 patients with nephrolithiasis. Unilateral calculosis was established in 46.3% of the patients, bilateral calculosis in 50.6%. The nature of changes on renograms, scintigrams and in clearance values was shown to depend on the localization of concrements, their size and the presence of concomitant infection. A conclusion has been made as to the usefulness of the methods with relation to operative treatment, especially in a bilateral localization of a pathological renal process.
