Your renal arteries supply oxygen-rich blood to your kidneys. In renal artery stenosis, these arteries become narrow or stiff, reducing the flow of blood to the kidneys. The condition can lead to high blood pressure and reduced kidney function.

What Causes Renal Artery Stenosis?
Renal artery stenosis is caused by buildup of sticky, waxy plaque in the walls of the renal arteries. Plaque causes the arteries to narrow and become stiff, which makes it harder for blood to pass through to the kidneys. This is the same disease process that causes coronary artery disease.
Renal artery stenosis can also be caused be a rare condition called fibromuscular dysplasia. In this condition, cells in the walls of the renal arteries overgrow and narrow the opening of the artery.
Renal Artery Stenosis Symptoms
Renal artery stenosis usually does not have any symptoms. You can live with the condition for years and not know it. Often, doctors notice signs of renal artery stenosis during a diagnostic procedure or test for another vascular condition.
Renal artery stenosis is a potential cause of high blood pressure. It is more likely to be the underlying cause of high blood pressure if you:
- Do not have a family history of hypertension
- First develop high blood pressure after age 50
- Do not respond to treatment with typical medications for high blood pressure
- Develop a significant increase in blood pressure
If renal artery stenosis is left untreated for a long period of time, it can reduce your kidneys’ ability to function normally. If this happens, you may experience symptoms of kidney failure, including:
- Decreased or increased or urination
- Muscle cramps
- Loss of appetite
