Renal artery stenosis is a narrowing of one or more of the arteries that carry blood to the kidneys (renal arteries). This results in reduced blood flow to the kidneys, which can lead to high blood pressure and damage to kidney tissue.

Acute hepatobiliary syndrome is an extremely dangerous condition that can be life-threatening. It is a form of progressive kidney failure that occurs in people with severe liver damage, most commonly due to cirrhosis. When the kidneys stop working, toxins begin to build up in the body and eventually lead to liver failure.
