Renal artery stenosis may be the narrowing of the renal artery , which causes renal arterial hypertension and ischemic nephropathy.
Renal artery stenosis is an unusual cause of hypertension, but a crucial one since it is curable. The ultimate way to detect hypertension is to contain routine blood pressure measurements.
Renal arterial stenosis has no overt symptoms. Ultimately, untreated renal arterial stenosis causes secondary complications such as chronic kidney failure , which might be characterized by consistent urination, anemia, edema , head aches, hypertension , lower back pain , and other signs or symptoms.
Patients may be treated medically with common antihypertensive drugs, or, occasionally, with renal artery angioplasty or bypass medical operation. Study participants were randomized to receive either medical remedy alone or medical remedy plus renal artery stenting. Occlusion may be acute or long-term. Acute occlusion is usually unilateral. Chronic occlusion could be unilateral or bilateral.

Likewise, two randomized studies published in '09 2009 - the ASTRAL trial and the Superstar trial - didn't show a clear advantage for renal artery stenting with respect to kidney function.
