title: [Classification of stages of renal tumors by means of computed tomography scanning (author's transl)].
abstract: Fifty-eight patients with malignant renal tumors were submitted to computed tomography scanning. Fifty patients were operated. In eight patients, the disease was too advanced to allow a surgical treatment. The preoperative classification of stages was made according to the Robson scheme and compared with the results of the postoperative histopathological examination. There were identical results in 82% of all operated patients. An analysis of the individual results (fat tissue infiltration, lymph node metastases, infiltration of adjacent organs or veins) shows that the method is limited by the uncertain estimation of the renal vein as well as of the beginning fat tissue infiltration. The good results should give occasion to adopt the computed tomography scanning of the kidney into the staging catalogue of IUCC. Computed tomography scanning should be the basic examination for preoperative staging of renal tumors.
