Prenatal diagnosis of persistent cloaca.
We report four cases of persistent cloaca diagnosed at 32-33 weeks of gestation. In cases of persistent cloaca, serial prenatal ultrasonography shows transient fetal ascites, enlarged cystic structures arising from the fetal pelvis. Our four cases of persistent cloaca were diagnosed prenatally. Persistent cloaca should be considered in any female fetus presenting with hydronephrosis and a large cystic lesion arising from the pelvis as assessed by ultrasound and magnetic resonance imaging. Neither pulmonary hypoplasia nor severe oligohydramnios were found in any of our four cases, and they each had a good prognosis. Prenatal diagnosis allows time for parental counseling and delivery planning at a tertiary care center for neonatal intensive care and pediatric surgery.
