| Abstract: | In 76 patients with space occupying lesions of the kidneys CT scans were performed. Size, shape and localisation of the kidneys could well be demonstrated by this method. Space occupying lesions were clearly seen, and solid tumors could be differentiated from cysts. However differential diagnosis between either primary renal cell carcinoma and metastases or between malignant and benign mass lesions was not possible. There was no problem in the diagnosis of hydronephrosis where as a differentiation between inflammatory changes and solid masses proved to be difficult. CT scanning seems to be usefull in the diagnosis of renal space occupying lesions. As a non invavise method it should be performed previous to renal angiography, which thereby becomes unnecessary in many cases. |
