Renovascular hypertension caused by renal artery stenosis is an uncommon but curative cause of hypertension in children. We report a case of recurrent severe hypertension caused by renovascular hypertension. After recurrence of hypertension after redo percutaneous transluminal renal angioplasty, the blood pressure was finally controlled by renal autotransplantation. This case demonstrates the importance of considering renovascular hypertension as a cause of severe hypertension in children. Also, renal autotransplantation should be considered as a viable treatment option for treatment of renovascular hypertension that is recurrent after renal angioplasty.
