The procedure uses a catheter to deliver radiofrequency or ultrasound energy to the nerves in the kidney arteries. This reduces nerve activity, which can help lower blood pressure over time.

This treatment is typically offered to people with resistant hypertension—blood pressure that remains high despite using multiple medications. It may also be considered for those who cannot tolerate high doses of blood pressure medications.

Yes, renal denervation has been proven safe in multiple clinical studies. It is performed by experienced specialists and involves no permanent implants or open surgery.

The procedure usually takes about 45 to 60 minutes. It is performed in a catheterization lab through a small incision in the groin or wrist.

You’ll be given mild sedation and local anesthesia, so you’ll feel relaxed and comfortable but may remain awake during the procedure.

Recovery is typically quick. Most patients go home the same day or next day and return to normal activities within a few days.

Some patients begin to notice improvements in blood pressure within a few weeks, but the full effect may take 1 to 3 months as nerve activity gradually decreases.

Many patients still take medications after renal denervation, but the goal is often to reduce the number or dosage of drugs needed to manage blood pressure.

Your doctor will provide clear instructions, including fasting before the procedure, stopping certain medications, and having blood pressure and kidney function tests done in advance.
