[Computed tomographic staging of hypernephroid carcinoma]

In 68 patients with renal cell carcinoma computed tomographic staging was compared to the histopathologic staging. The classification based to the staging scheme developed by Robson. The CT criticized the tumor stages correctly in 82%. Consequently CT is superior to angiography, especially in detecting infiltration of the peri- and pararenal space and of lymph node metastases. Difficulties were found in detecting tumor extension into the renal vein near by the renal hilus.
