title: [Value of angiography, sonography and computer tomography in the differential diagnosis of renal space-occupying lesions].
abstract: 157 space-occupying lesions of the kidneys (89 cysts, 57 malignant tumours, 8 benign tumours, 1 abscess, 1 non-traumatic bleeding and a special form of inflammation, namely, xanthogranulomatous pyelonephritis) which were observed in 2 years, were evaluated, using angiography, ultrasound and computed tomography. If a space-occupying lesion is found--mostly by I.V. urography--ultrasound should be applied next for differentiating the cyst from the solid tumour. If this is not possible, or if a solid tumour is found, the next step should be computed tomography. (Staging of carcinoma, diagnosis of angiomyolipoma or another benign tumour, eg.. a lipoma). Angiography as an invasive procedure is indicated only in cases in which ultrasound and computed tomography don't yield a diagnosis. (Possibility of pharmacoangiography and magnification angiography).
