The urachus forms from the distal end of the allantois in the embryo, and develops into a closed cord between the base of the bladder, and the navel.[1] It drains the bladder of the fetus that joins and runs within the umbilical cord.[2] The fibrous remnant lies in the space of Retzius, between the transverse fascia anteriorly and the peritoneum posteriorly. At birth, the urachus develops into the median umbilical ligament.[3][4]
