Ultrasonic dopplerography of the renal arteries was used to improve the differential diagnosis of arterial hypertension before hospitalization. Dopplerograms of the renal arteries of normal subjects were characterized by almost symmetrical parameters of the blood stream. In patients with vasorenal hypertension a marked asymmetry of the blood stream was seen with its reduction and qualitative changes in the dopplerogram on the side of the stenosed renal artery, that was confirmed by angiographic findings. Chronic pyelonephritis was dopplerographically characterized by hemodynamically insignificant asymmetry of the blood stream in the renal arteries with its reduction on the side of the involved kidney. In essential hypertension the type of asymmetry of blood stream parameters in the renal artery seemed similar to that in normal subjects.

[A diagnostic center in the practical public health system].

The authors describe a clinical diagnosis center working in close cooperation with a chair of therapy. Analysis of the activities of the center demonstrated the usefulness of medical divisions of such kind for practical health service, for it is at such diagnostic centers that profound examinations of patients, making use of present-day diagnostic methods, is possible at the preclinical stage. Such a possibility was offered to the residents of a large region who previously had to be hospitalized for this purpose. A diagnostic center brings evident economic benefit and is a clinic where physicians of primary health centers upgrade their knowledge and skills.
