Abstract:
Objective: To investigate prenatal ultrasonographic features of fetal cloacal exstrophy. Methods: Prenatal ultrasound and birth/autopsy results of 12 fetuses with cloacal exstrophy were analyzed retrospectively. The ultrasonic features of cloacal exstrophy were observed and compared with pathologic findings. Results: Prenatal ultrasonography showed omphalocele in 11 cases, bladder non-visualization in 8 cases, anal atresia in 8 cases, neural tube defect (acrococcygeal mass or absence of vertebrae) in 7 cases. The mainly accompanied abnormalities included lower limb deformity in 2 cases, urinary malformation in 5 cases, ambiguous genitalia in 9 cases, intrauterine growth restriction in 1 case, heart malformation in 2 cases, digestive tract abnormalities in 2 cases, single umbilical artery in 1 case, nuchal translucency thickening with hydrocephalus in 1 case. Conclusion: When prenatal ultrasound found features such as omphalocele, bladder non-visualization, anal atresia and ambiguous genitalia etc., cloacal exstrophy should be considered.
