Prenatally diagnosed patent urachus with bladder prolapse: Case Report and review of the literature

Persistent urachal anomalies are rare congenital lesions of the urinary tract. They result from the failed obliteration of the urachus and are classified according to persistent segment of the urachus. Patent urachus represents complete connection between the bladder and the umbilicus. An unique to newborns form of patent urachus is bladder prolapse inferior to umbilical cord, through the widely patent urachus. This is the least common urachal abnormality, however, because of very characteristic fetal ultrasound picture, can be diagnosed prenatally which allows for the proper treatment after the birth. We report a case of prenatally diagnosed patent urachus with bladder prolapse and its postnatal management. The literature on the subject is enclosed.
