[Evaluation of the contractile capacity of the ureter and kidney pelvis in tuberculosis by the method of infusion dynamic uretero- scintigraphy].

The radionuclide method--infusion dynamic ureteroscintigraphy--was used to examine 123 patients with tuberculosis of the urinary organs and 51 patients of the control group. Contractility parameters of various portions of the ureters and pelves in varying urinary tuberculosis were established. The contractility of the pelves and ureters was proved to be impaired even prior to the appearance of visible X-ray changes in the ureters. A specific increase in contractility in the area from the pelvis to the middle third of the ureter and further reduction in the lower third were seen.
