Renal Angioplasty
Renal angioplasty is a procedure that uses a small balloon to widen the passage through your renal artery. This is the main blood vessel that supplies your kidneys. A stent is a small metal mesh tube put into a blood vessel to help hold it open and improve the blood flow.
If your renal artery is narrowed or blocked, it can cause severely high blood pressure or problems with how your kidneys work. Renal angioplasty and stenting can help make blood flow to your kidney better and ease problems. The procedure is often done by a specially trained healthcare provider called an interventional radiologist. This is a healthcare provider who is trained and certified by the American Board of Radiology to use minimally invasive image-guided procedures to diagnose and treat diseases.
You'll change into a hospital gown and lie on an X-ray table. An IV (intravenous) line is started in your arm or hand. This is to give you fluids and medicines. You may be given medicine through the IV to help you relax.

Symptoms
Renal artery stenosis is often found by accident in patients who are undergoing tests for another reason. Symptoms factors include:
- Older age
- Being female
- Having hypertension
- Having other vascular disease (such as coronary artery disease and peripheral artery disease)
- Having chronic kidney disease
- Having diabetes
- Using tobacco
- Having an abnormal cholesterol level
Renal artery stenosis usually does not cause any specific symptoms. Sometimes, the first sign of renal artery stenosis is high blood pressure that is extremely hard to control, along with worsening of previously well-controlled high blood pressure, or elevated blood pressure that affects other organs in the body.
