A Case of Patent Urachus / 대한산부인과학회잡지

ABSTRACT

Patent urachus results when there is a persistence of an allantosis remnant which normally undergoes atresia during embryological development. Failure of urachal obliteration may result in 4 different types of urachal remnants complete patency or vesicoumbilical fistula, vesicourachal diverticulum, urachal sinus and urachal cyst. In prenatal ultrasound, we found a large cyst in the umbilical cord. At term, the patient underwent primary cesarean section with delivery of a 3100 g female infant. After delivery, we found the communication of urinary bladder by fistulogarm. The infant underwent repair and closure of the patent urachus.
