What Is Renal Denervation?

Renal denervation is a minimally invasive treatment that helps control high blood pressure. It is typically performed in addition to lifestyle changes and medications.

Renal denervation targets overactive nerves in the renal arteries, which carry blood to the kidneys. These overactive nerves can increase blood volume, constrict blood vessels, and activate hormonal responses—all contributing to high blood pressure. By disrupting the overactive nerves, renal denervation helps regulate resistant high blood pressure.

Prior to the FDA’s approval of renal denervation, lifestyle changes and medication were the only treatment options for high blood pressure. Renal denervation offers patients an additional treatment option.

What Does Renal Denervation Treat?

Renal denervation treats high blood pressure, also called hypertension. If left unchecked, hypertension can increase the risk for coronary heart disease and stroke.

Who Is a Good Candidate for Renal Denervation?

Renal denervation may be a good option for patients who haven’t been able to manage their blood pressure through medication and lifestyle changes alone.

Speak with your healthcare provider to determine if renal denervation is right for you.

What to Expect During Treatment

Renal denervation takes around an hour, and patients are sedated to ensure relaxation and comfort. Most patients go home the same day.

During the procedure, the doctor will make a small incision in the groin to insert a very thin tube, also known as a catheter, into the artery leading to the kidney. The doctor will then use a device to calm the overactive nerves near the kidney. After the nerves have been treated, the doctor will remove the tube.

After Treatment

The incision area may be sore for a few days, though most patients can typically resume normal activities after a week.

Patients should continue to take medications as directed by their healthcare provider and continue their healthy lifestyle changes. Many patients will begin to see gradual reductions in their blood pressure over the next several months.
