A case of renovascular hypertension with the nephrotic syndrome

Nephrotic range proteinuria occurred in a 42-year-old woman with renal arterial occlusion and hyperreninemia. The administration of captopril, an angiotensin converting enzyme inhibitor, led to an amelioration of the proteinuria and the decrease of blood pressure, without surgical treatment. From the present observation, it is highly probably that the increased activity of the renin-angiotensin system plays an important role in massive proteinuria. Conservative treatment for renovascular hypertension with nephrotic syndrome was effective in this patient.
