Uterus Ultrasound with Saline

What is Sonohysterography (Ultrasound of the Uterus)?

An ultrasound of the uterus, also known as Sonohysterography or saline infusion sonography, is a special, minimally invasive ultrasound technique. It provides pictures of the inside of a woman’s uterus.

A Doppler ultrasound study may be part of a sonohysterography examination.  This is a special ultrasound technique that evaluates blood as it flows through a blood vessel.


What is this procedure used for?

It may be used to diagnose unexplained vaginal bleeding due to conditions such as:

  • Polyps
  • Fibroids
  • Endometrial atrophy
  • Endometrial adhesions (or scarring)
  • Malignant lesions/masses
  • Congenital defects

It can also be used to investigate uterine abnormalities in women who experience infertility or multiple miscarriages.

Doppler ultrasound images can help us to see and evaluate:

  • Blood flow blockages
  • Blood flow in polyps, tumours and congenital malformation
  • Pelvic varicose veins and aneurysms.

When is it best to have this procedure?

Advisedly, this procedure is best performed one week after your menstruation. At this time in the menstrual cycle, the endometrium is at its thinnest, which is the best time to determine if the endometrium is normal. Sonohysterography should not be performed if you are pregnant.

This ultrasound examination is usually completed within 30 minutes.  It is well tolerated by most patients.
