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 retrospective comparative assessment of the diagnostic value of excretory urography (EU), scintigraphy (SCG) and ultrasonography (USG) of the kidneys was conducted in 100 patients. The diagnosis in 26 patients was confirmed by CT, angiography, at operation or autopsy. Chronic pyelonephritis was diagnosed in 54% of the patients, renal changes in essential hypertension--9%, hydronephrosis in 8%, abnormal shape and position of the kidneys in 8%, malignant tumors in 7%, chronic glomerulonephritis in 8%, renal cysts in 2%, multicystosis in 1%, kidney contusion in 1%, paranephritis in 1%, and apostematous nephritis in 1%. The sensitivity of EU was 71%, that of SCG 52%, that of USG 93%. The specificity of EU was 66%, SCG--8%, that of USG 90%.
