Renal Denervation
A catheter-based treatment that modifies sympathetic nerves around the renal arteries in selected patients with uncontrolled hypertension.

Overview
Renal denervation aims to support blood-pressure reduction by applying controlled energy within the renal arteries. It complements, rather than automatically replaces, lifestyle and medication management.
Who may be considered?
It may be considered when blood pressure remains uncontrolled despite appropriate treatment, after adherence and secondary causes of hypertension have been carefully reviewed.
How is the procedure performed?
A catheter is advanced to both renal arteries and delivers radiofrequency or ultrasound energy at planned points along the vessel wall.
Recovery and follow-up
Blood pressure and the access site are monitored after the procedure. Medication changes are made only by the treating physician, with continued home and clinic measurements.
Risks and safety
Access-site bleeding, renal artery injury, contrast-related kidney problems and an insufficient blood-pressure response are possible.
