[Computerized tomography of kidney tumors].

Among 220 renal tumors which we detected by computed tomography, there were 168 renal cell carcinomas, 24 tumor of the renal pelvis, 16 angiomyolipomas, 6 Wilms tumors, 3 oncocytomas, one liposarcoma, one mesenchymal tumor, and one rhabdomyosarcoma. Computed tomography had the highest accuracy of the diagnostic procedures with a sensitivity of 99.5% and a specificity of 98%. 83% of the renal cell carcinomas showed signs of malignancy in computed tomography; the staging of the renal tumors by computed tomography was correct in 67% of the cases. The diagnostic value of other diagnostic tools (sonography, urography, angiography, cavography) of renal tumors is discussed in terms of our own results.
