Kidney failure is loss of the ability of the kidneys to remove waste and concentrate urine without losing electrolytes. Most people with kidney failure must have dialysis, a mechanical procedure for removing waste from the blood, since their kidneys are no longer able to perform this function.
Narrowing (blockage) of the renal arteries is an important cause of hypertension and kidney failure. It is often caused by atherosclerosis (hardening of the arteries), but fibromuscular dysplasia and other lesions can also cause narrowing.
Renal Artery Stenosis or Blockage Treatment
While traditional surgical methods (renal artery bypass) are sometimes still used to treat this condition, a newer, less invasive procedure — called renal artery stenting — has become the most common treatment at MedStar Union Memorial Hospital. Learn more about renal artery stenting.
