Renal hypoplasia is a condition in which the kidneys are small because of developmental parenchymal deficit. Essential to this definition is the notion of normally developed and differentiated individual nephrons and ducts, without coexisting dysplasia. Affected renal artery and intrarenal blood vessel branches are relatively hypoplastic and commonly sclerotic. Stenosis of main arteries or its branches are apt to cause hypertension. The pathogenesis of hypoplastic kidneys may involve a diminished number of nephrons and diminished nephrotic size. We experienced a 4-year-old boy with 180/130mmHg of blood pressure, and confirmed renovascular hypertension due to a typical unilateral renal hypoplasia. Nephrectomy was done and the blood pressure returned to normal. Abdominal ultrasonogram, CT, aortic angiography, and pathologic findings are presented with a brief review
Key Words: Renal hypoplasia, Renovascular hypertension, Nephrectomy
