title: [Arterial hypertension. Prevention in infants with congenital urinary tract malformations].
abstract: Eighty-nine newborns and infants with congenital urinary tract malformations were treated in the childrens' hospital of the Westfälische Wilhelms-University from 1986 to 1989. Twenty patients of this group (22.5%) developed severe hypertension requiring treatment within the first year of life. Mean age of diagnosis of hypertension was 5 months (range 0.5-12 months). Median values for blood pressure at time of diagnosis were 138 mmHg (range 120-170) for systolic and 92 mmHg (range 80-110) for diastolic values. Six patients showed characteristic symptoms for hypertension such as restlessness, sweating and sleep disorders. Plasma levels of renin were obtained in 12 of 20 patients. Five patients had raised plasma renin levels. All patients with a severe hypertension were treated with one to several antihypertensive drugs. Risk factors for the development of severe renal hypertension in early infancy are cystic renal malformation, vesico-ureteral reflux, obstructive uropathy and to our experience also short term percutaneous nephrostomy in obstructive uropathy in particular in connection with pyelonephritis. Hypertension can still appear after the successful surgical correction of urinary obstruction. We describe the group of patients with severe hypertension in our study group; diagnostic principles and our therapeutic approach are explained. We conclude that early diagnosis of severe hypertension and consecutive treatment are important in infants with congenital urinary malformations.
