title: Antepartum chronic fetal vesicoamniotic shunts for obstructive uropathy: A report of two cases.
abstract: Two fetuses with obstructive uropathy characterized by striking oligohydramnios and dilatation of the urinary collecting system were identified by ultrasound and treated by percutaneous insertion of a long-term vesicoamniotic silicone rubber shunt. Both fetuses were less than 16 weeks' gestation at diagnosis and less than 18 weeks at treatment. One fetus was delivered at 35 weeks and is alive and well; the other died early in the neonatal period at 31 weeks with pulmonary hypoplasia.
