Patent urachus with bladder eversion.
An infant was born at term after having received a diagnosis of omphalacele on prenatal ultrasound scan. She did not have an omphalacele but rather had a patent urachus with bladder eversion onto the abdominal wall. The remainder of the genitourinary tract was normal, and it was possible to pass a soft catheter through the urethra and out of the evaginated bladder. The prolapse was repaired without complications, and the infant recovered uneventfully. A voiding cystourethrogram and renal ultrasound scan were normal at 2 month follow-up. The embryology and malformations of the urachus are discussed, and the rare case reports of similar anomalies are reviewed.
