Infant with drainage of urine through the umbilicus

VCUG of patent urachus and urachal diverticulum
Lateral image from a voiding cystourethrogram performed by catheterizing the site of urine drainage at the patient’s umbilicus shows contrast filling the bladder and urethra as well as a large diverticulum at the dome of the bladder that nearly extends to the patient’s anterior abdominal wall.

The diagnosis was patent urachus and a urachal diverticulum.
