Renal angiography is an imaging test used to study the blood vessels in your kidneys. The procedure is done through a thin, flexible tube called a catheter. The catheter is put into a blood vessel through a small cut or incision. X-ray dye, also called contrast medium, is injected.
Renal Stenting
Renal artery stenting is a procedure to open the renal arteries — the large blood vessels that carry blood to the kidneys — when they have become blocked due to renal artery stenosis (narrowing of the renal artery). Stenting opens the blockage and restores normal blood flow. Renal Artery Stenting Menu.
