Preparing for your pelvic ultrasound

Quick reference

What is a pelvic ultrasound

A pelvic ultrasound uses sound waves to produce images of the organs and structures in the pelvis. This commonly includes the uterus, ovaries, fallopian tubes, bladder and surrounding soft tissue. It may be performed abdominally (with the probe on the skin over the lower abdomen) or transvaginally (using a slim probe gently inserted into the vagina), or both techniques may be used in the same appointment.

Why might it be requested

Pelvic ultrasounds are commonly requested to investigate pelvic pain or discomfort, irregular, heavy or absent periods, suspected fibroids or ovarian cysts, urinary symptoms, or other gynaecological or pelvic concerns. The reason for your referral is a matter for you and your referring clinician.

How should I prepare

General guidance: for an abdominal pelvic ultrasound, you are usually asked to arrive with a comfortably full bladder. A full bladder pushes the uterus and ovaries upward, improving the image quality. General guidance is to drink approximately 1 to 1.5 litres of water about one hour before your appointment, and not to empty your bladder before arriving. For a transvaginal ultrasound, an empty or only partially full bladder is usually preferred. If both types are planned, your clinic will tell you what preparation is needed. Always follow the specific instructions given by your imaging centre, as requirements can vary.

What should I wear

Wear comfortable, two-piece clothing. You will need easy access to your lower abdomen and may be asked to undress from the waist down for a transvaginal scan. You will be given privacy and a sheet or gown.

What happens during the scan

For an abdominal pelvic scan, the sonographer applies gel to your lower abdomen and moves a probe gently over the area to produce images. For a transvaginal scan, you will be asked to undress from the waist down. The sonographer will cover a slim probe with a single-use sterile cover and apply gel before gently inserting it into the vagina. You will be kept informed throughout and can ask the sonographer to stop at any time. Both techniques are generally well tolerated.

Will it hurt

An abdominal pelvic ultrasound is generally painless, although a very full bladder may feel uncomfortable. A transvaginal ultrasound may cause mild pressure or discomfort, but should not be significantly painful. Tell the sonographer immediately if you feel significant pain.

How long does it take

A pelvic ultrasound appointment typically takes 15 to 30 minutes. If both an abdominal and transvaginal scan are performed, the appointment may be slightly longer.

When will I get results

Results are sent to the clinician who requested your scan. They will discuss findings with you at a follow-up appointment or by letter or phone. Contact your imaging centre or referring clinician if you have questions about when you will receive results.

When should I contact the clinic

Contact your clinic if you are unsure about bladder preparation; if you are on your period (some clinics prefer to reschedule); if you have had recent pelvic surgery; or if you are pregnant or think you may be pregnant. If you have any concerns about the transvaginal scan, discuss these with the clinic before attending.

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