Renal artery stenosis is a disease of narrowing of the arteries that carry blood to the kidneys. These arteries are known as renal arteries and are responsible for supplying the kidneys with oxygen-rich blood. The oxygen-rich blood helps the kidneys to filter waste and excess fluid from the body. When the renal arteries narrow, the oxygen\u2013rich blood flow to the kidneys is reduced therefore limiting the functions of the kidneys and can eventually lead to increased high blood pressure, kidney damage and edema.<\/p>\n
