Renal sympathetic denervation (RSDN) is a minimally invasive, endovascular catheter based procedure using radiofrequency ablation or ultrasound ablation aimed at treating resistant hypertension (high blood pressure not controlled by medication). [1]
Renal denervation involves using radio frequency or ultrasound to eliminate the sympathetic nerve supply to the kidney wall, aiming to lower blood pressure and treat chronic hypertension. [11] Renal denervation has become less common in recent years due to new evidence indicating that the procedure does not significantly lower blood pressure.
Medical device maker St. Jude Medical has announced that it is moving forward with a study to determine if renal denervation and medication can improve the health of patients with uncontrolled ...
Inhibition of the neural impulses that are believed to cause or worsen hypertension has been tried for a few decades. Surgical sympathectomy has helped but not without significant side effects. Therefore, the introduction of non-surgical means of renal denervation using a radiofrequency ablation catheter was enthusiastically welcomed.

This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
New research shows that not only do sugary drinks increase your risk for serious conditions such as heart disease and type 2 diabetes, but they are also linked to hundreds of thousands of deaths ...
Other treatments may include denervation, autotransplantation, renal neurectomy, or nephrectomy. Unfortunately symptoms often recur following these procedures. Limited evidence suggests that drugs that inhibit angiotensin may reduce the frequency and severity of episodes of loin pain and gross hematuria.
