Pelvic internal ultrasound: what to know

The sonographer explains the process and places a covered, lubricated probe gently into the vagina while you are positioned comfortably. The probe sends sound waves to create images; it does not use ionising radiation. The examination may help assess pelvic pain, bleeding, fertility-related questions, early pregnancy, or the appearance of the uterus and ovaries. It cannot by itself provide every diagnosis, and results are interpreted with your symptoms and clinical history.

Ask whether you need a full or empty bladder, because preparation varies with the type of scan. Tell the service if internal examination may be difficult, if you have pain, or if you prefer a female clinician or chaperone. You may ask for an explanation before each step, request a pause, or stop the examination. Wear clothing that allows easy access while preserving your privacy.

Mild temporary discomfort can occur, but contact the service if you have heavy bleeding, severe or increasing pain, fever, faintness, or unusual discharge afterward. Seek urgent help for severe pain with dizziness or collapse. If the scan was arranged for ongoing symptoms, follow the agreed plan for discussing the report even when the examination felt normal.

Ask what the scan is intended to investigate, whether an abdominal scan is an alternative, how bladder preparation works, and when results will be available. If you are pregnant or could be pregnant, tell the clinician so the examination can be planned appropriately.
