Renal Artery Stenosis

Renal artery stenosis is the narrowing of one or both of the arteries that carry blood to the kidneys, which reduces blood flow to these organs. That decrease can affect blood pressure and kidney function.

Possible presentations: blood pressure that is hard to control, changes detectable in kidney studies, and, at times, an absence of clear symptoms.

Associated factors: hardening of the arteries and other vascular changes are usually behind this narrowing.

Which specialists assess it? The nephrologist evaluates the impact on the kidney, while the angiologist and the vascular surgeon address the condition of the arteries; in children, the pediatric nephrologist takes part. In the face of hard-to-manage blood pressure or abnormal kidney studies, it is advisable to discuss it with one of these professionals.
