[Scintigraphic study of the kidneys with a 99m Tc-ascorbic complex in chronic pyelonephritis patients].

A scintigraphic study of the kidneys was carried out in 1780 patients with chronic pyelonephritis: 1308 with calculous and 472 with acalculous pyelonephritis. The scintigraphic finding was interpreted for each kidney separately. Diffuse damages of renal parenchyma was most often observed (47,6%), being, in the majority of the cases--bilateral. Disturbed drainage was established in 13,2%, dysfunction of one of the kidneys--in 18,8% and focal disturbed structure--in 5,4% of the kidneys studied. The results from the scintigraphic study were juxtaposed to the clinic of the disease and the data from laboratory and X-ray investigations. The scintigraphic study of the kidneys with 99m Tc-ascorbic complex is easy to perform, well tolerated by the patients, non-invasive method with no special risks, with minimal irradiation loading. Scintigraphy provides valuable information to the clinicians about the functional, structural and drainage disorders in the kidneys of patients with chronic pyelonephritis, allowing the control of the evolution of the disease and the effect of the treatment.
