title: [The radiological diagnosis of pyelocaliceal tumors. Accent placed on the value of arteriography, especially after the angiotensin test (author's transl)].
abstract: From a study of 22 cases of excretory pathway tumors, which had undergone simple selective arteriography, complemented in certain cases by an angiotensin test, the authors were able to draw the following conclusions: -In those forms which show a pyelocaliceal lacuna on intravenous pyelography, arteriography does not help in making a diagnosis; in particular it does not help in distinguishing malignant forms from benign forms. It is therefore of no practical value and is not indicated in such cases. -In those forms showing caliceal amputation or a non functioning kidney on intravenous pyleography, arteriography nearly always enables the diagnosis of a tumor and confirms considerable parenchymal invasion. Its practical value is evident and it seems that it is always indicated in such cases. -Interpretation of the documents must always be thorough, looking for minor signs, while being aware of possible causes of error.
