The allantois is a structure that connects the bladder of the developing fetus to the umbilicus. It normally shrinks and becomes non-functional after birth, but in some cases, a small part of the allantois persists and can lead to leakage of clear yellowish fluid from the umbilicus. This condition is known as urachal remnants or urachal cysts.
