Y1 - 2015 N1 - T2 - Fetology: Diagnosis and Management of the Fetal Patient, 2e AB - Key PointsPersistent cloaca refers to the continuation of the early embryological stage of a common opening for the rectum, vagina, and urinary tract.This is an extremely rare abnormality, being seen in only 1 in 50,000 births.Fetal abdominal cystic masses are the most typical prenatal diagnostic features, usually due to hydrocolpos and associated bladder outlet obstruction.Following the prenatal diagnosis, targeted fetal ultrasound, amniocentesis, and fetal MRI are helpful in accurately delineating the fetal anatomy.Postnatal surgical reconstruction is complex and should be undertaken only by a multidisciplinary pediatric surgical team after complete neonatal radiological and endoscopic anatomic evaluation.Long-term outcome appears favorable after surgical correction with the majority of patients being continent of urine and feces and several having successfully delivered children.
