- Abstract
The authors report the case of an 8-year-old Libyan boy who presented with hypertension, episodes of vomiting and headaches during the past year. Routine blood tests, including nitrogen and urea clearances, were normal; an ultrasound scan and a urography demonstrated a left kidney smaller than the right. Further tests were carried out to evaluate the morphology and the function of the kidney; a scintigraphy confirmed the hypoplasia of the left kidney with reduction of the glomerular filtration rate. The arteriography of the abdominal aorta was decisive, confirming not only the hypoplasia of the left kidney, but also the presence of a hypoplasic renal artery. The latter appeared to be uniformly hypoplasic, with no signs of segmentary stenosis. This fact suggested the hypothesis of renovascular hypertension caused by a hypoplasia of the renal artery. The medical treatment with enalapril gave good results, with normalization of the pressure levels after 5 days of administration. However, only nephrectomy is able to give excellent long-term results.
