Transvaginal ultrasound - what to expect

Quick reference

What is a transvaginal ultrasound

A transvaginal ultrasound is a type of pelvic scan where a slim, smooth probe is gently inserted into the vagina to produce detailed images of the uterus, ovaries and surrounding pelvic structures. Because the probe is positioned close to these structures, it can often produce clearer images than an abdominal scan alone.

Why might it be requested

A transvaginal scan may be used to investigate pelvic pain, abnormal bleeding, suspected ovarian cysts or fibroids, early pregnancy, or other pelvic conditions. It may be performed alongside an abdominal pelvic scan as part of the same appointment.

How should I prepare

Unlike an abdominal pelvic scan, a transvaginal scan does not usually require a full bladder. You may be asked to have an empty or only partially full bladder. Always follow the preparation instructions given by your clinic or imaging centre, as guidance can vary.

What should I wear

Wear comfortable clothing. You will be given privacy and the opportunity to undress from the waist down. A sheet or gown will be provided.

What happens during the scan

You will lie on an examination couch with your knees bent. The sonographer will explain the procedure before starting and will ask for your consent. A single-use sterile cover is placed over the probe, which is lubricated with gel. The probe is then gently inserted into the vagina. You will be kept informed at each stage and can ask the sonographer to stop at any point. The sonographer will move the probe gently to capture images from different angles.

Will it hurt

The scan should not be painful, although you may feel mild pressure or discomfort. If you experience significant pain at any point, tell the sonographer immediately and they will stop. If you are very anxious about the scan, let the clinic know before your appointment so they can support you.

Can I decline the transvaginal scan

Yes. You may decline a transvaginal ultrasound at any time, including after the scan has started. If you do, the sonographer may offer an abdominal scan as an alternative, though the image quality may not be as detailed for some conditions. It is your right to ask questions and to make an informed decision about your care.

How long does it take

The scan typically takes 15 to 25 minutes.

When will I get results

Results are sent to the clinician who requested your scan. Ask your doctor or imaging centre about how and when you will receive your results.

When should I contact the clinic

Contact your clinic if you have questions about the scan, if you are on your period, if you have had recent vaginal or pelvic surgery, or if you have any other concerns before attending.

Always follow your clinic specific instructions. The information here is general guidance only. Your clinic may have different requirements.
