Abstract：Renal sympathetic denervation (RDN) with radiofrequency energy is a novel therapeutic technique for the treatment of patients with resistant hypertension. Nevertheless, radiofrequency ablation of renal sympathetic nerves bears numerous disadvantages, e.g., low efficiency; patient’s suffering from pain during ablation and unresponsiveness to the treatment, as well as successful procedural performance depending on the type of target vessels, etc. While ultrasound, when longitudinally propagating through the biological tissue, may cause the medium molecules to vibrate violently, with subsequent generation of mechanical friction, cavitation and thermal effects; thus, can be applied for RDN. Compared with radiofrequency energy, it has many advantages in terms of safety and efficacy. This review is about the-state-of-art of ultrasound ablation for renal sympathetic nerves.
