Endocavity Ultrasound — Transvaginal Ultrasound

An internal pelvic ultrasound that provides detailed images of the uterus and ovaries.

What is it?

A transvaginal ultrasound is an internal scan in which a slim, covered ultrasound probe is gently inserted into the vagina. Because the probe is close to the pelvic organs, it can provide more detailed images of the uterus, endometrium, ovaries and surrounding structures than an external scan. It does not use radiation.

Is it for me?

• Pelvic pain or unexplained lower abdominal symptoms
• Heavy, irregular or post-menopausal bleeding
• Suspected fibroids, polyps, ovarian cysts or endometriosis
• Fertility concerns or early-pregnancy questions when clinically appropriate
• An abnormality seen during examination or on an external pelvic scan
• The thickness or appearance of the endometrium
• Follow-up of a known gynaecological condition

Preparing for your test

• A full bladder is not required; you will usually be asked to empty your bladder before the scan
• You may eat, drink and take usual medicines unless advised otherwise
• Wear comfortable clothing that is easy to remove from the waist down
• A period does not usually prevent the scan; remove a tampon or menstrual cup before the examination
• Tell the clinician if you may be pregnant, have never been sexually active, have experienced pelvic pain or trauma, or have concerns about the examination so that alternatives and support can be discussed

What to expect

• The examination will be explained and your consent obtained before it begins
• You will undress from the waist down in privacy and be covered with a sheet
• The slim probe is cleaned, covered with a protective sheath and lubricated before gentle insertion into the vagina
• The probe is moved slightly to obtain images; you may feel pressure, but tell the clinician immediately if you experience pain
• You remain in control and may ask for the examination to pause or stop at any time; a chaperone can be present
