Patients with renal artery stenosis may present with one or more of the following (see Presentation):

  • Abdominal bruit

  • Azotemia

  • Sudden worsening of hypertension or kidney function

  • Acute kidney injury or decreased kidney function after initiation of antihypertensive therapy, especially with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs)

  • Unexplained kidney insufficiency, in elderly patients

  • Congestive heart failure, with poor control of hypertension and kidney insufficiency in the absence of a significant decrease in ejection fraction (so-called flash pulmonary edema)
