Renal Denervation Therapy

Renal Denervation Therapy Abroad

Renal denervation (RDN) is a minimally invasive procedure to treat resistant hypertension. The procedure uses radiofrequency ablation to burn the nerves in the renal arteries. This process causes a reduction in the nerve activity, which decreases blood pressure. The interventional radiologist will insert a catheter into the femoral artery in your thigh, and through this will access the arteries feeding your kidneys.

During the RDN procedure, radiofrequency pulses are applied, burning the nerves in the walls of the renal arteries. The aim of the procedure is to burn the renal nerves without damaging the arteries. Each application of radiofrequency ablation will last for around 1-2 minutes, though this depends on the device used. The interventional radiologist may use a catheter (tube) radiofrequency generator, which requires more than one application of the radiofrequency pulse during the session, or a radiofrequency balloon generator, which requires a single application of radiofrequency pulse.
