Saline Infusion Sonohysterograms

This technique is used to detect abnormalities of the uterine cavity and the endometrium.  Essentially a small amount of fluid is injected into the uterus through a fine tube to outline the uterine cavity.

What are the common reasons for having this examination?

  • Suspected abnormalities of the uterus - either ones you were born with or new ones.  eg. fibroids.
  • Further evaluation of abnormalities seen on transvaginal scan.  eg. in women with suspected polyps of thickening of the endometrium beyond the menopause.
  • Investigation of sub-fertility and recurrent miscarriage.
  • If the lining of the uterus was not able to be seen clearly on routine scanning

You should not have the procedure if you are pregnant or may be pregnant at the time of the examination or you have acute pelvic infection or unexplained pelvic tenderness which may be due to pelvic inflammatory disease.  Saline infusion is not done with an intra-uterine device (IUD) in place.

How is the Procedure Performed?

On the day of the procedure a transabdominal and/or transvaginal ultrasound of the pelvis may be performed immediately prior to the procedure. A speculum will be placed in the vagina and the cervix will also be cleansed with antiseptic. A fine (2 mm) plastic tube is passed through the cervix into the uterus. The speculum is removed and a vaginal ultrasound scan is then performed as the saline (sterile salt water) is injected.

Will I need an anaesthetic?

Whilst you may experience some mild discomfort, this is not usually a painful procedure and therefore no anaesthesia is required. However, to minimise crampy discomfort, 2 tablets of Bucopan is recommended 1 hour before the procedure. (These can be obtained from the chemist over the counter) 

How will I feel after the procedure?

You may have some period-like cramps. Most women are comfortable enough to drive home and continue with usual daily activities, but if you are concerned about pain it may be worthwhile having someone available to drive you home. Local heat (hot water bottle or wheat bag) applied to the lower abdomen may be helpful to manage pain.

Some dark discharge from the vagina may be expected due to the Betadine antiseptic solution, so you may like to bring a panty-liner with you to the appointment.
If you develop symptoms of infection in the days after the procedure (eg. fever, loss or appetite, pelvic pain, unusual vaginal discharge) see your doctor as early as possible.
