A urachal sinus may open at the umbilicus and produce a discharge.The allantois,running between the umbilicus and the urinary bladder,usually becomes the urachus and,eventually,the median umbilical ligament.If the cranial part of the allantois remains patent,a sinus may form.More often,the caudal end of the allantois remains patent and gives rise to a sinus that may be continuous with the cavity of the urinary bladder.
