Transient renovascular hypertension in childhood.

Two children aged 18 and 30 months presented with severe renovascular hypertension. Initially, surgical intervention was postponed because of the patients' young age. Adequate control of the hypertension and reversal of its sequelae were achieved with aggressive medical management. At present, both patients, aged 9 and 12 years respectively, have discontinued all medication, have achieved normal growth, are normotensive and have normal renal function.
