The results showed no statistically significant difference between renal denervation and the sham procedure. [4] Following the publication of Symplicity HTN-3 the Joint UK Societies produced a consensus statement that did not recommend the use of renal denervation for treatment of resistant hypertension in routine clinical practice.

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.
Although the initial use of radiofrequency-generated heat to ablate nerve endings in the renal arteries to aid in management of 'resistant hypertension' were encouraging, the most recent phase 3 studying looking at catheter-based renal denervation for the treatment of resistant hypertension failed to show any significant reduction in systolic ...
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
Since Page kidney is a unilateral process, symptom presentation differs significantly depending on if patients have native kidneys or only one functioning kidney, such as renal transplant recipients. [2] In those with a normally functioning second kidney, the only symptom may be new-onset hypertension.
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.
Angiotension converting enzyme. The pathogenesis of renovascular hypertension involves the narrowing of the arteries supplying the kidneys which causes a low perfusion pressure that is detected by the juxtaglomerular apparatus (via the macula densa cells, which act as baroreceptors; located on the afferent arteriole wall).
