Double shunt in a case of fetal low-level obstructive uropathy.

This report describes a pregnant woman at 22 weeks of gestation examined for fetal bilateral dilated renal pelvis and oligohydramnios. Ultrasound evaluation confirmed the diagnosis of low-level obstructive uropathy. At 26 weeks of gestation, the increase in hydronephrosis prompted us to introduce a vesicoamnionic shunt. Because of unusual intraperitoneal dislocation of the shunt and an increase in ascites and hydronephrosis, we had to insert a peritoneoamnionic shunt at 30 weeks of gestation. The patient underwent cesarean section at 31 weeks for obstetric complications. The infant, at 15 months of age, showed mild renal failure.
