Pelvic ultrasound Q&As

Answers to questions about pelvic ultrasound

This section contains answers to common questions about this topic. Questions have been suggested by health professionals, website feedback and requests via email.

Can I have a transvaginal ultrasound during a period?

The best time to have a transvaginal ultrasound is a week after your period. However, the procedure can be done during a period if needed. So women with irregular periods shouldn't worry if their appointment date is during their period.

Explanation

A transvaginal ultrasound is used to examine the womb lining, fallopian tubes and ovaries. During the procedure a lubricated sensor is passed into your vagina. The sensor is usually covered with a condom. Please tell your ultrasonographer if you have latex allergy, so that a suitable condom can be used.

The examination can be done at any time during a woman's life - in pregnancy, during a period or after the menopause.

If you have a regular menstrual cycle it's best to arrange an appointment in the first half of the menstrual cycle (in the first two weeks of having your last period). The womb lining is at its thinnest during this time and it's easier to detect any problems.

Can I have a transvaginal ultrasound if I'm a virgin?

The sensor is about the size of a tampon. So women who can tolerate tampons will usually feel no discomfort during the scan.

Explanation

The ultrasound sensor is very slim. It's usually covered with a condom and well lubricated before it's inserted into the vagina. Most women will not feel any discomfort. However, talk to your doctor or ultrasonographer if you have any concerns about the scan.

Do I need to take laxatives before a transrectal ultrasound?

Yes, you will usually be asked to take a laxative 24 hours before your scan.

Explanation

A transrectal ultrasound is usually done along with a biopsy of the prostate gland in men. A biopsy is a small sample of tissue. This is sent to a laboratory for testing. The prostate is a gland that produces the liquid part of semen. It's about the size of a walnut and lies at the base of your bladder close to the rectum. To examine the prostate a lubricated sensor is passed into your rectum. The sensor is usually covered with a condom. Tell your ultrasonographer if you have latex allergy, so that a suitable condom can be used.

You will usually be asked to clear your bowel before your appointment. Your doctor will explain how to prepare for your scan. You may be given laxatives to take the evening before or on the morning of the procedure. These will help empty your bowel.
