Abstract
A case of bladder prolapse through a patent urachus is reported in a female infant born with a large, red, tubular mass inferior to the umbilical cord. A cystic mass communicating with fetal bladder was detected by prenatal ultrasound performed at 20(+2) weeks of gestation. A fetal MRI was also performed to confirm the diagnosis and to exclude associated fetal anomalies. At 40(+4) weeks, the cystic mass was no longer present and a new small solid mass was noted at the fetal abdominal wall. After birth, a protruded mucosal mass inferior to the umbilical cord was noted, and catheterization confirmed communication between the protruded mass and the urinary bladder. On the second day of life, reduction of the bladder and partial resection of the urachus was performed. A voiding cystourethrogram showed good bladder capacity and no vesicoureteral reflux. The patient voided well and was discharged after 10 days. Here, we present a case of urinary bladder prolapse through a patent urachus, diagnosed by fetal sonography and this is the first case reported that was treated by simple excision without complication.
Key Words: Urachus, Bladder prolapse, Newborn
