[The capsule sign in severe hydronephrosis (author's transl)].
In severe obstructive disease of the kidney, with major distension of the intrarenal collecting ducts and marked thinning of the parenchyma, intravenous urography with high doses of contrast medium may reveal, almost pathognomic nephrographic abnormalities, such as, the dense capsule appearance, or septal appearances. The diagnostic value of these radiological appearances is all the greater in these very advanced cases of hydronephrosis, opacification of the excretory ducts can often not be obtained.
