Women's Intervention


What is a Sonohysterogram?

A Sonohysterogram is a simple ultrasound procedure designed to look at the endometrial cavity (the inside part of the uterus) and the endometrium (the lining of the endometrial cavity).

Why would I need a Sonohysterogram?

Your doctor may refer you for this test for a number of reasons, including:

  • Looking for a lesion in the endometrium, such as a polyp.
  • Investigation of postmenopausal bleeding.
  • Assessing the shape of the endometrial cavity.


A HyFosy are usually done under ultrasound. Again a small catheter is introduced into the uterus and is held in place by inflating a small balloon. A contrast agent is then introduced into the uterus and fallopian tubes via the catheter. The test shows if the uterine cavity is normal and if the fallopian tubes are open. Fibroids, scar tissue, or polyps in the uterus can also be identified.


When a small balloon is inflated, you may experience some mild cramping, similar to period pain. Please take some oral pain relief, such as Nurofen Plus or Paracetamol before the examination.

An HSG usually takes approximately 1 hour.

How is a Sonohysterogram performed?

The first part of the sonohysterogram is like the first part of a pap smear. The cervix is then cleansed with antiseptic solution, to decrease the risk of infection. A thin flexible catheter is inserted through the opening of the cervix, so that the catheter lies within the endometrial cavity. The vaginal speculum is then removed, with the catheter remaining inside. Next, the transvaginal ultrasound (internal scan through the vagina) is used to image the uterus. A small amount of sterile saline is introduced into the endometrial cavity through the catheter. This saline distends the endometrial cavity, allowing better assessment of the contour and shape of the endometrium.

Hysterosalpingogram (HSG)/Lipiodol Flush

What is a Hysterosalpingogram (HSG)?

A Hysterosalpingogram is an X-ray procedure where contrast is used to look at the inside of the fallopian tubes and uterus.  To accomplish this, we need to insert a speculum into the vagina similar to having a Pap smear test. We then insert a thin plastic catheter into the uterus and inflate a small balloon to keep it in place. The X-ray contrast is then passed through the small tube and into the uterine cavity and fallopian tubes, the X-ray pictures are taken with a fluoroscopy X-ray machine.

HSG/Lipiodol Flush

A Lipiodol HSG is performed on referral only from a fertility specialist.

It is a therapeutic procedure which has been shown to increase conception rates, particularly in women with endometriosis. Before this is done patent fallopian tubes must be confirmed with either an HSG or Laparoscopy & Dye.

There is no specific preparation but as with other HSGs, it should be timed with the menstrual cycle to occur between day 5 and 10 of cycle.

The procedure has been available as a treatment in since 2003. Its effectiveness and safety as an aid to fertility treatment. The findings of this procedure has been based on two recent trials and a thorough literature review for all high quality therapeutic trials in which Lipiodol or similar oil-soluble contrast media have been used.

Lipiodol flushing received ethical approval as an innovative treatment from 2003 to 2007, subject to satisfactory data collection and follow up. This data collection has now been satisfactorily completed.

  • Usually performed between day 7-10
