[Radionuclide diagnosis of the ureteral motor function and urodynamics in renal tuberculosis and other diseases of the urinary system].

Radionuclide methods (a new technique of infusion dynamic ureteroscintigraphy and standard techniques of dynamic and static scintigraphy of the kidneys, radionuclide renography) were used to examine 134 patients with nephrophthisis, 61 patients with other urological diseases and 51 controls. It is shown that nephrophthisis brings urodynamic disorders and impairment of ureteral contractility. Three types of the contractile disorders are distinguished. A decline in motor function and urodynamic defects occurred also in other urological affections. Sensitive radionuclide techniques are thought valuable in examination of the urinary system and objective evaluation of urodynamic disorders.
