Abstract:

Renal sympathetic innervation plays an important role in blood pressure regulation. Gradual activation of renal sympathetic efferent nerves enhances renin release, promotes sodium and water re-absorption, and reduces renal blood flow and glomerular filtration rate. On the other hand, activation of renal afferent sympathetic nerves induced by renal injury results in central sympathetic activation. This reciprocal relationship between the kidneys and the brain is involved in the pathogenesis of hypertension and other disease conditions characterized by sympathetic overactivity. Renal sympathetic nerve ablation has been recently introduced for the treatment of resistant hypertension. This review aims to provide the pathophysiological basis of renal nerve ablation for the attenuation of sympathetic overactivity.
