O60-O75: Complications of labour and delivery

O73: Retained placenta and membranes, without haemorrhage

Retained placenta and membranes, without haemorrhage, refer to a group of conditions that occur when part or all of the placenta or membranes remain in the uterus after childbirth. These conditions usually present when the uterus is unable to contract enough to expel the placenta fully. This can happen due to several reasons, including certain maternal conditions, the placenta embedding deeply into the uterine wall, or incomplete separation of the placenta from the uterus. Common symptoms include prolonged bleeding after delivery, pain in the lower abdomen, an unusually large uterus upon examination, and sometimes fever. If not promptly treated, these conditions could lead to severe infection or other serious complications. Therefore, these conditions typically require medical intervention to remove the retained placenta or membranes and to manage any associated symptoms.
