Retained placenta ultrasound: what it can show

After birth or pregnancy loss, an ultrasound creates images of the uterus using sound waves. It may help a clinician look for material that could represent retained placental tissue, assess the uterine lining, and consider other explanations for bleeding or pain. A scan does not replace a clinical assessment: normal postpartum changes, clots, or healing tissue can affect the appearance, and the image alone may not settle the diagnosis.

Tell the service about your bleeding pattern, pain, fever, discharge, dizziness, and the date of the pregnancy event. Follow the instructions given for the examination; depending on timing and local practice, the scan may be performed over the abdomen or with a vaginal probe. Ask when the result will be discussed and what the next step will be if the scan suggests retained tissue or is inconclusive.

Seek emergency care for rapidly heavy bleeding, faintness, severe or worsening pelvic pain, confusion, difficulty breathing, or fever with shaking chills. An ultrasound appointment should not delay treatment for possible major blood loss or infection. Contact a clinician promptly for ongoing bleeding, fever, or foul-smelling discharge even if a scan has already been arranged.

Ask what the scan is looking for, whether another test is needed, and how the result will change your care. You may also ask whether the findings fit your symptoms, whether treatment is advised now, and how follow-up will check that recovery is progressing.
