Understanding what to expect from a sonohysterogram

A sonohysterogram is a transvaginal ultrasound that uses saline (salt water) to evaluate the contour of the uterine cavity. The goal is to make sure your uterine cavity is a healthy and unobstructed place for a pregnancy to grow.

During this procedure at our Las Vegas fertility center, we insert a soft catheter through the cervix using a speculum. The speculum is then removed and a transvaginal ultrasound probe is inserted. Under real-time imaging, we then send normal saline through the catheter in order to slowly fill the uterine cavity like a balloon. This test allows us to see small abnormalities in the uterine lining.

It is important to confirm that you are not pregnant during this exam so it is done after your menstrual bleeding has stopped.

What is the purpose of a sonohysterogram?

A sonohysterogram is a routine part of most infertility work-ups at our Las Vegas fertility center. It allows our team to get a close look at the endometrial cavity. On a regular transvaginal ultrasound, we can see the thickness of the endometrial lining. However, there can be small findings like polyps, fibroids, scar tissue or a uterine septum that are difficult to see.

With a sonohysterogram, we can see any irregularities of the endometrial lining that could interfere with pregnancy, especially small irregularities that cannot be seen when the uterine cavity is empty.

In addition to doing this test as part of your infertility work-up, we will often repeat this test if you have had a pregnancy or a miscarriage recently. The goal is to confirm there is no residual tissue within the uterine cavity.

Who will perform my sonohysterogram?

One of our ultrasonographers will perform this exam at our Las Vegas fertility center.

Are there any side effects associated with this procedure?

It is normal to feel significant leakage from the vagina. This is the saline solution and iodine soap that is used to wash the cervix before the procedure. Occasionally, women will have some cramping during the procedure that resolves once the exam is done.

What can I do to increase my comfort at this visit?

Most patients tolerate this procedure very well. However, you may plan to take extra strength ibuprofen after the procedure if needed for cramping.

What will FCLV do to increase my comfort?

Our team will talk you through the procedure so that you know exactly what is going on.

What are the next steps?

You may have some vaginal spotting after the procedure that should get lighter and stop within one to two days. Additionally, the iodine used to clean the cervix can leave a brown discharge, so you will want to wear a pad for the rest of the day.

This may be one of the final diagnostic tests of your infertility work-up. At the time of this procedure, you will want to confirm that you have completed all the recommended tests, and then schedule a follow-up consultation with your doctor to review the results.
