title: [Place of computed tomography in the diagnosis and assessment of the spread of malignant kidney tumors].
abstract: The value of computed tomography was assessed in 52 patients with malignant kidney tumors, of whom 34 had undergone nephrectomy. Findings on the CT scan in a small group of 9 patients, when it was employed mainly for diagnostic purposes, gave true results in 7 cases, its contribution being decisive in 3 of these 7 cases. Scanning replaced arteriography for evaluation of tumor spread in 40 patients, where it was found to be very effective for assessment of perirenal, pararenal and lymph node extension. A high percentage of doubtful results were obtained during the first few years of use of the CT scan for determining state of veins (renal vein and inferior vena cava). Subsequent refinements in technique markedly improved the incidence of positive results. Computed tomography should be employed as the method of first choice for determining the stage of malignant kidney tumors.
