SONOHYSTEROGRAM

 

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.

 

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.
