title: [Management of children with prenatally diagnosed urinary tract abnormalities].
abstract: Between 1984 and 1991, antenatal ultrasound scanning detected urinary tract malformations in 126 infants, who were investigated and treated postnatally in the childrens' hospital of the Westfälische Wilhelms-University Münster. 10 out of 126 children with urogenital changes, died in the first hours after birth, due to pulmonary hypoplasia (Potter's sequence), 1 further infant died later after cardiac operation, and another died of megacystic-megaureter-hypoperistaltic-syndrome. In the first months after birth 71 (61%) of 116 infants underwent urological surgery; 12/116 infants (10.3%) had severe bilateral kidney changes, some of them with severe deficiency of amniotic fluid before birth. 6/116 infants (5.2%) had chronic renal insufficiency, 2 of them will have to be dialyzed in early childhood and longterm, 14 patients (12%) are threatened by chronic renal failure. 14 patients (12%) developed severe arterial hypertension, all had to be treated with antihypertensive drugs, in 5 of them hypertension subsided after unilateral nephrectomy, another five had transient hypertension, but four require continued medical treatment. We describe the prenatal ultrasound findings, compared them with diagnosis after birth, illustrate diagnostics, plans of therapy, urological surgical interventions and nephrological consequences. Benefits and limitations of antenatal ultrasonography for the detection of urinary tract malformations and the treatment of those malformations before and after birth are discussed. In utero diagnosis of severe urinary tract abnormalities allows treatment of these infants immediately after birth, furthermore the prevention of severe infections, additional damage of renal tissue, and early diagnosis and treatment of arterial hypertension and metabolic imbalances caused by chronic renal insufficiency in early childhood.
