[Dynamic scintigraphy of the kidneys during chronic pyelonephritis in patients with arterial hypertension].

It has been shown that latent renal diseases are detected by sectoral scintigraphy earlier than by other methods, and the former acquires particular importance when the only sign of disease is arterial hypertension. Early diagnosis of latent pyelonephritis makes this method especially valuable both for the selection of patients for further thorough examination and for the start of adequate therapy. Scintigraphy serves as a reliable criterion for the evaluation of the therapeutic efficacy in patients with chronic pyelonephritis (CP). Changes of scintigraphy parameters coincide quite exactly with the changed level of arterial pressure, concentration and nitrogen clearing function of the kidneys during treatment. This method (sectoral scintigraphy) is very important when used over time in CP patients with chronic renal insufficiency making it possible to detect with a sufficient degree of significance the improvement as well as impairment of renal function which is a crucial point for the choice of further therapeutic tactics.
