What is a hysterosonogram?

A hysterosonogram is a minimally invasive ultrasound technique that provides ultrasound images of the inside of a woman’s uterus. This technique allows for an extensive evaluation of the endometrial lining of the uterus. It is often used to evaluate for uterine abnormalities in women who experience unexplained vaginal bleeding and infertility. A hysterosonogram can provide information about uterine abnormalities that may not be seen on a routine transvaginal ultrasound.

Why is this test performed?

The purpose of a hystersonogram ultrasound is to find a reason for unexplained vaginal bleeding or infertility.

What should I expect during this test?

This test is performed by an ultrasound sonographer. You will lie on your back with your feet in stirrups. A sterile speculum will be inserted into the vagina (similar to when you have a pap smear). A small catheter will be inserted into the uterine cavity at which time you may experience some pressure in your pelvis. Once the catheter is in place, the speculum will be removed and the sonographer will insert the transvaginal probe in the vaginal cavity. Sterile saline will then be injected through the catheter into the uterine cavity while the ultrasound images are being taken. The saline distends the uterine cavity, allowing for evaluation of the endometrial lining.

How do I prepare for this test?

You must have had a baseline transvaginal ultrasound at least three months prior to a hystersonogram. If possible, it is best to perform a hysterosonogram when you are not bleeding. You should not have a hysterosonogram if you are pregnant or think you might be pregnant.

Are there any risks associated with a hysterosonogram?

There is no risk associated with a hysterosonogram. You might experience some cramping and discomfort during the procedure. This typically lasts only a few minutes.
