Vascular impressions on the ureters.

摘要: Impressions upon the ureters accounted for by extrinsic pressure defects exerted adjacent or crossing arteries and veins are frequently noted on urographic studies. The observation of these is usually made, but their significance often overlooked. We have discussed illustrated those conditions which may result in ureteral notching an arterial venous basis.The causes impressions include:1. accessory normal renal arteries;2. compression a iliac artery;3. artery stenosis;4. aortic occlusion;5. cirsoid aneurysm artery;6. impression hypogastric aneurysm.The be due to:1. gonadal vein defect right left;2. ovarian syndrome;3. varicocele varices broad ligament;4. occlusion inferior vena cava below level tumor, clot, retroperitoneal fibrosis, follo...
