Renal artery stenosis
Typically, affected patients will have a normal urinalysis. If both renal arteries are involved (as is more commonly seen with atheromatous disease), progressive renal impairment is observed, often with significant fluctuations in glomerular filtration rate dependent upon volume status.
Affected patients often have particular sensitivity to angiotensin-converting enzyme inhibitor therapy, with (usually reversible) acute kidney injury evident on medication initiation. Severe hypertension with episodes of flash pulmonary edema may be seen with unilateral or bilateral disease.
