Prenatal diagnosis of persistent cloaca accompanied by uterus didelphys: A case report
Journal Title: Turkish Journal of Obstetrics and Gynecology - Year 2021, Vol 18, Issue 1
Abstract
Persistent cloaca is a rare abnormality that occurs usually in females and is characterized by direct communication between the gastrointestinal, urinary, and genital structures resulting in a single perineal opening. We report a case of persistent cloaca accompanying uterus didelphys that was diagnosed antenatally with fetal ultrasonography. A gravida 3, para 2, 35-year-old women at 22 weeks of gestation was referred to our hospital with a diagnosis of moderate pyelectasis of the fetal kidneys and fetal diffuse intestinal dilation. Detailed ultrasound scan findings were reported as a small thick-walled septated cystic pelvic mass of 5.2×5.5 cm size seen at the level of the fetal pelvic region. The target sign could not be visualized, it was considered as anal atresia. In the following weeks, the patient, who was evaluated together with meconium on the uterine septum, and monitoring of the neighboring bladder and anal atresia, was diagnosed as having persistent cloaca. Ultrasound findings showed that it could be persistent cloaca accompanying uterus didelphys. The fetus postnatally manifested persistent cloaca. On the first day after vaginal delivery, pelvic ultrasound in the neonatal intensive care unit showed bilateral 2nd-degree hydronephrosis, presacral enlarged bowel loops, uterus didelphis, vaginal septum, direct contact between urethra and vagina, proximal end in the rectum compatible with atresia. On the second day, colostomy was performed. Her renal condition continued to be stable. She is now waiting for definitive surgery for cloaca. Persistent cloaca should be considered in any female fetus presenting with hydronephrosis and a cystic pelvic mass lesion as diagnosed by ultrasound. Prenatal diagnosis allows time for parental counseling and delivery planning at a tertiary hospital for neonatal intensive care and pediatric surgery.
