Renal sympathetic denervation for resistant hypertension in a patient with a single kidney

To the Editor: We report a case of successful renal sympathetic denervation (RSD) treatment for resistant hypertension in a patient with a single kidney.1-3 RSD is performed via femoral arterial access, using a radiofrequency ablation catheter to deliver energy to the renal artery wall. When delivering RSD to a single kidney, potential renal artery vascular complications can have a significant negative impact on a patient’s renal function, compared with patients with two functioning kidneys.
