Background: Fetal obstructive uropathies complicated by severe oligohy
dramnios can cause neonatal death due to renal dysplasia and pulmonary
hypoplasia. Case: A 31-year-old multigravida was referred at 19.6 wee
ks with sonographic evidence of fetal megacystis and bilateral hydrour
eteronephrosis, and severe oligohydramnios. A vesicoamniotic shunt was
placed for urinary diversion. Complications included shunt migration,
intestinal evisceration, amniorrhexis, preterm labor, and preterm del
ivery. Bowel characteristics were assessed by measuring the intestinal
lumen diameter for evidence of obstruction. The lumen diameter remain
ed stable at 3-5 mm, and the luminal wall remained stable at 2.5 mm. A
fter birth at 31 weeks, the infant underwent exploratory laparotomy an
d extraction of malpositioned shunts, vesicostomy, and closure of abdo
minal wall defect. He was discharged at 61 days of life after resoluti
on of neonatal pulmonary and infectious complications. Conclusion: Ope
rative management of complete fetal obstructive uropathy is beneficial
despite potential complications. (C) 1998 by The American College of
