Background: During embryonal period, complete obliteration of the urachus at the umbilicus and incomplete closure at the bladder level are the cause of vesicourachal diverticulum. This abnormality is a rare finding that is usually discovered incidentally during radiological evaluation. Occasionally, stones have been detected within the diverticulum.
