Lethal fetal renal anomalies and obstetric outcome

The incidence of prenatal and intrapartum complications was examined among 33 pregnancies complicated by lethal fetal renal abnormalities (cases) and compared to 200 contemporaneous control pregnancies (controls) by retrospective record review. Cases experienced higher rates of antepartum bleeding (29% vs. 6%, p<0.0001) stillbirth (15% vs. 0%, p<0.0001), preterm birth (34.3+/-4.1 vs. 39.7+/-1.8, p<0. 0001) and breech presentation (48% vs. 4%, p<0.0001). Twenty-six of 33 cases had lung weights
