Renal artery stenosis care at Mayo Clinic

Your Mayo Clinic care team

Mayo Clinic doctors trained in kidney diseases and high blood pressure (nephrology and hypertension), vascular and endovascular surgery, diagnostic and therapeutic (interventional) radiology, heart and blood vessel diseases (cardiovascular diseases), and vascular medicine work together to evaluate and treat people with renal artery stenosis. Each year, more than 1,000 people with renal artery stenosis are treated at Mayo Clinic.

Having all this expertise in a single place means that your care is discussed among the team, test results are available quickly, appointments are scheduled in coordination and the most highly specialized heart experts in the world are all working together for your health.

Advanced diagnosis and treatment

Mayo Clinic offers a wide variety of diagnostic options for renal artery stenosis, including Doppler ultrasound, computerized tomography (CT) scan, magnetic resonance angiography (MRA) and renal arteriography.

Mayo also offers blood oxygen level dependent (BOLD) magnetic resonance imaging, a specialized procedure that evaluates how much oxygen your affected kidneys are receiving to determine whether restoring blood flow in your kidneys' arteries may be of benefit.

Mayo Clinic Division of Nephrology and Hypertension is undertaking the first study of using a person's own mesenchymal stem cells, which are harvested from fat tissue, to repair the damage to the kidneys.

Research leaders

Doctors at Mayo Clinic have a long-standing interest in research related to renal artery stenosis. Findings from research studies can lead to new and improved treatments. Current clinical trials underway include repair of injured kidney tissue with the administration of a person's own mesenchymal stem cells and the use of investigational protective agents (mitochondrial protection) at the time of revascularization.
