Abstract:
Roentgenologic procedures are of limited value, compared with other possible examinations. Early radiologic diagnosis is made rarely. Roentgenologic procedures are important for demonstration of successful treatment and for legal documentation. Excretory urography is effective only in combination with zonography and ureteral compression provided the amount of injected contrast medium is sufficient. Angiography is important in progressive or silent renal tuberculosis, especially in cases of a partial or complete non-functioning kidney. Difficulities in differential diagnosis are possible in unspecific pyelonephritis and malignant tumors.
