Renal denervation is a minimally invasive procedure used to treat hypertension (high blood pressure) by disrupting the nerve signals to the kidneys that regulate blood pressure. This procedure involves inserting a catheter into the renal arteries and using radiofrequency energy to ablate the nerves surrounding the arteries, thereby reducing the kidneys' ability to release hormones that increase blood pressure. Renal denervation has shown promising results in reducing blood pressure levels in patients with resistant hypertension who do not respond well to medication. Further research is being conducted to assess the long-term effectiveness and safety of this procedure.
