A Case of Drug-Resistant Renovascular Hypertension due to Renal Artery Stenosis Successfully Treated by Nephrectomy of the Affected Kidney.

INTRODUCTION

Renal artery stenosis (RAS) reduces renal blood flow and activates the renin-angiotensin-aldosterone (RAA) system, resulting in renovascular hypertension (RVH).

CASE PRESENTATION

We report a case of a 49-year-old woman with RVH due to bilateral renal artery stenosis, predominantly on the right. Despite pharmacological treatment, blood pressure remained poorly controlled; leading to severe heart failure that required dialysis. Percutaneous renal angioplasty was considered but deemed technically difficult. The patient underwent a successful laparoscopic right nephrectomy, leading to improved blood pressure control and reduced need for antihypertensive medications.
