[Influence of computed tomography on diagnosis cost in renal tumoral syndromes (author's transl)].

The cost of computed tomography has been compared with that of other exploratory procedures in two groups of patients with renal tumoral syndromes. Reduced duration of stay in hospital and reduced number of arteriographies in cases of renal cancer, much lesser use of diagnostic puncture-aspiration in cases of renal cysts are the most obvious benefits of the new method.
