To differentiate pregnancies complicated by oligohydramnios due to intrauterine growth retardation from those due to renal agenesis, the authors administered furosemide intravenously to eight pregnant women (19-25 weeks gestation) with oligohydramnios. The fetal abdomen was scanned with ultrasound to demonstrate the fetal urinary bladder. In six fetuses, sonography failed to demonstrate the bladder: two fetuses had growth retardation with normal kidneys and bladder, and four had renal anomalies. It is concluded that administration of furosemide to the mother fails to induce diuresis in growth-retarded fetuses of 19-23 weeks gestation and that failure to see the fetal bladder after furosemide administration does not necessarily indicate absent fetal kidneys.
