Background: Sympathetic complex of over-activation kidneys is one of the main causes of primary hypertension (HTN). We aimed to assess the efficacy and safety of sympathectomy using 5Fr mariner catheter ablation on patients with refractory hypertension.Methods: In this prospective cohort study, patients who received three or more anti-hypertensive medications with 160mmHg systolic blood pressure (BP) or more were randomly included and divided into 2 groups.

Both groups were followed for six month by assessing BP and adverse effects.Results: One hundred and seventeenth patients (54%) out of 212 screened patients were included in the first group (renal denervation) and 95 patients as the second group. The mean of BP changes in the first group was 35/15 mmHg with standard deviation of 22/11mmHg. (P
