Severe hypertension in hypoplastic kidney and bilateral renal artery stenosis: report of one case.

A three year-old boy was found incidentally to have severe hypertension (around 200/110 mmHg) when he was brought to This Hospital's Emergency Department because of his abdominal pain. After his admission, serial and detailed examinations were performed. These included: basic blood chemistry studies, abdominal and renal sonography, excretory urography, radionuclide scintigraphy and angiography with selective renal vein renin sampling. Diagnosis was made of renovascular hypertension with combination of unilateral renal hypoplasia and bilateral renal artery stenosis. The patient was given oral anti-hypertensive drugs, with resulting satisfactorily controlled blood pressure after two weeks of treatment. He was discharged without surgical intervention.
