Renal Arteriography
Alternate Names : Renal Angiogram
DefinitionA test to examine the blood vessels of the kidneys, using contrast material and X-rays. See also renal venogram.
These arteries are difficult to fully examine on an ordinary X-ray, so a contrast material is injected into one or more arteries so they may be seen and evaluated.

Why is the Test Performed?
The test is done to evaluate the blood vessels that feed the kidney. The test may detect stenosis (narrowing of the blood vessel), blood clots, or aneurysm (a widening of the vein or artery). The test may help evaluate kidney disease or failure, tumors, or kidney function.
It is often used to evaluate donors and recipients before transplantation of a kidney to determine the number of arteries and veins on each kidney.
Some vascular tumors in the kidney can be partially treated by embolizing (placing material in the vessel so it clots and becomes occluded) the feeding arteries.
