What is a retained placenta?
Let's start with the basis. The placenta is a temporary organ that connects the fetus to the lining of the womb through the umbilical cord.
The placenta is very crucial: on the one hand, it keeps the baby's blood supply separate from the mother's. On the other hand, it provides the link between the both and caries out the functions that the unborn baby can't perform itself. The placenta also protects the baby against infecitons.
Once the baby is born, the placenta is usually delivered with a couple of contractions. Usually, but not always. Sometimes it remains partly or wholly in the womb and can't be delivered naturally. The condition is called a retained placenta.
The retained placenta can be a result of difficult labour and woman's loss of strength. If not timely addressed, a retained placenta can lead to endomyometritis and postpartum hemorrhage.
