ABSTRACT
Fetal posterior urethral valve syndrome results in potentially lethal complications including renal dysplasia, pulmonary hypoplasia. Antenatal fetal vesicocentesis and amniotic fluid infusion may be useful to improve neonatal pulmonary function, however rapid recurrence of urinary retention and oligohydramnios usually required repetitive invasive procedures. We successfully treated a posterior urethral valve syndrome with vesico-amniotic shunt. Under ultrasonographic guidence, we inserted a Double-Basket Catheter into fetal urinary bladder through lower abdominal wall at second trimester. Shunt remained in place until the fetus was delivered at 35th gestational week. The vesico-amniotic shunt can improve fetal outcome and avoid repeated vesicocentesis before delivery.
