It usually requires some kind of repair - surgery or dilatation.

How do you usually diagnose renal artery stenosis?

How do you usually diagnose renal artery stenosis?

Renal arter stenosis: The diagnosis is made with ultrasound dopplers to check blood flow rates that reveal waves created by the blockage, or arteriograms.Ultrasound has no risk, but is very operator dependent and can be misleading in both over and under diagnosis.Arteriograms are more accurate, but only show an anatomic blockage, and don't help with functional testing. Finding blocks doesn't mean they need treatment. ...Read more

Fmd is a non-inflammatory, nonatherosclerotic process. Both atherosclerosis and fmd cause hypertension and can lead to kidney failure. Imaging should be done to establish the diagnosis. Kidney specialists usually treat this dx. ...Read more
