[Scanner examination of the kidney]

On the basis of a large series of documents, the authors participate in establishment of the classification of scanner appearances of urological diseases of the kidney : peripheral or parapelvic sub-capsular cysts, carcinomas and their spread, multiple tumours but of different nature in the same kidney, angiomyolipomas, polycystic disease, renal abscess, hydated cyst, non-invasive exploration of kidneys showed to be non-functioning by I.V.U., tumours of the intrarenal excretory system, lumbar trauma, long-term surveillance of the retroperitoneal space in individuals undergoing surgery for a urological malignant renoureteric tumour. The authors suggest a new chronological arrangement of investigations in the presence of a renal mass discovered by I.V.U. Scanner has its place between echotomography and renal arteriography. Investigations may be stopped at renal echotomography when this examination offers definite evidence of the fluid nature of the mass. Solid or doubtful nature of the mass necessitates the use of a scanner examination.
