title: [The current status of vascular investigations in urinary pathology (author's transl)].
abstract: The author reviews the current position regarding vascular investigations in urinary pathology, with particular emphasis on arteriography.--In the presence of a renal mass. Arteriography is necessary in the presence of a mass, though bearing in mind that it offers more information about the state of the renal vessels than diagnostic arguments since the diagnosis of carcinoma of the kidney is confirmed in 9 cases out of 10 before renal arteriograms are performed. However, in the 10% of cases of doubtful diagnosis, renal arteriography offers valuable arguments in the presence of necrosed carcinomas. When the renal vein is not opacified, invasion is highly likely, and hence cavography is indicated.--In hypertension, arteriography is limited to very young sufferers with hypertension of sudden onset and in those cases where timed IVU is in favour of arterial obstruction.--In the presence of isolated haematuria, arteriography has never detected a carcinoma when the IVU is normal. By contrast, in cases of recurrent isolated haematuria, the administration of intra-arterial angiotensin before selective arteriograms or selective renal phlebograms has led to the detection of a certain number of haemorrhagic vascular lesions: arteriovenous fistulae, angiomas, varicosities.--In the presence of a true non-functioning kidney by IVU, renal arteriography is indicated only when there is a renal tumor solid by echotomography.--In renal trauma, the role of arteriography as an immediate emergency is limited to non-functioning kidneys by IVU, and as a delayed emergency preoperatively.--In tumours of the upper excretory tract, renal arteriography is of value only in tumours with calyceal amputation and invasion of the renal parenchyma.--In renal insufficiency, more information may be obtained from cavo-urography (abnormal in retroperitoneal fibrosis) than arteriography.
