165 renal carcinomas: accuracy of imaging for diagnosis and spread--cost efficiency.
Based on a study of 165 cases of renal carcinoma, we compare the relative diagnosis efficiency of different methods: intravenous urography (IVU), ultrasound (U.S.), arteriography and computed tomography (C.T.). Our evidence enables us to assert the excellent diagnostic accuracy of ultrasound and the superiority of computed tomography for good staging of renal carcinoma. The cost efficient methods for the evaluation of this tumour are intravenous urography (to show and localize the renal mass), ultrasound (to assert the echogenic structure) and computed tomography (to establish the diagnosis of carcinoma and judge its spread).
