Renal artery stenosis is a relatively common finding in older patients with hypertension. However, renal artery stenosis is the primary cause of hypertension (ie, renovascular hypertension) only in certain settings.

In most cases of renal artery stenosis, one kidney is affected, with the main vessels to the second kidney being essentially normal, hence the designation, "unilateral" disease. Individuals with high-grade stenosis to both kidneys, or to a solitary functioning kidney thereby affecting the entire functioning renal mass, are considered to have "bilateral" disease.

The treatment of unilateral atherosclerotic renal artery stenosis will be reviewed here. Clinical clues suggesting the presence of renovascular hypertension and establishing the diagnosis of renal artery stenosis, treatment of bilateral atherosclerotic renal artery stenosis, issues related to chronic kidney disease associated with atherosclerotic renovascular disease, and diagnosis and treatment of fibromuscular disease are presented in detail elsewhere. (See "Evaluation of secondary hypertension" and "Establishing the diagnosis of renovascular hypertension" and "Treatment of bilateral atherosclerotic renal artery stenosis or stenosis to a solitary functioning kidney" and "Clinical manifestations and diagnosis of chronic kidney disease resulting from atherosclerotic renal artery stenosis" and "Clinical manifestations and diagnosis of fibromuscular dysplasia" and "Treatment of fibromuscular dysplasia of the renal arteries".)


Epidemiology — The prevalence of renovascular hypertension is probably less than 1 percent in patients with mild hypertension but may be as high as 10 to 40 percent in patients with acute (even if superimposed on a preexisting elevation in blood pressure), severe, or refractory hypertension [1]. (See "Evaluation of secondary hypertension", section on 'Clinical clues for renovascular hypertension'.)

In three prospective treatment trials of patients with renal artery stenosis, the prevalence of unilateral disease (compared with bilateral disease) ranged from 53 to 80 percent [2-4]. Most patients with unilateral renal artery stenosis can be managed with antihypertensive drug therapy.
