A retained placenta occurs when the placenta, either whole or partial, does not come away from the uterine wall after the baby is born. If this occurs your doctor or midwife will recommend you be treated for a retained placenta. The options available will depend on your caregiver’s experience and the hospital policies. If the placenta cannot be removed using non-surgical methods it will need to removed manually by a doctor, usually in theatre with a spinal or epidural anaesthetic or under general anaesthetic if necessary.
