Urachus or median umbilical ligament is obliterated allantois.
Further descent of the bladder at 4th-5th month of gestation into the fetal pelvis results in the formation of the urachal canal, which later forms a fibrous tract, extending from the anterior bladder wall towards the umbilicus, as the median umbilical ligament, within the space between the peritoneum and trasversalis fascia.
