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 .
