ABSTRACT

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%.
