What is renal artery stenosis (ras)?

Narrowed artery(ies) Narrowing of one or both renal arteries that lead from the aorta to the kidneys is called renal artery stenosis. Causes are atherosclerosis or fibromuscular dysplasia (fmd). Fmd is a non-inflammatory, nonatherosclerotic process. Both atherosclerosis and fmd cause hypertension and can lead to kidney failure. Imaging should be done to establish the diagnosis. Kidney specialists usually treat this dx.
