title: [Sonography, urography and angiography in kidney carcinoma. A comparative study].
abstract: In a comparative study the validity of angiographic, sonographic and urographic findings for evaluation of 204 renal tumors was investigated. Angiography showed 97% correct results, sonography 96% and urography 93%. Mean tumor size was 8.4 cm. 25% of all tumors caused renal vein occlusion. On the one side there is a striking correlation between tumor growth and vein occlusion, and on the other side between vein occlusion and urographic silent right kidney. 20% of all tumors had metastasized at the time of diagnosis. In 4.5% of all cases we found a left sided symptomatic varicocele of the left side with invasion of the left renal vein by tumor masses.
