Sonohysterogram - MacArthur Medical Center

What is a sonohysterogram?

A sonohysterogram is a special gynecologic imaging technique that involves placing fluid into the uterus while an ultrasound is being performed. It takes place in an office, clinic, or hospital. By distending the uterine cavity with fluid, more structural abnormalities in the uterus can be seen.

When is a sonohysterogram done?

A sonohysterogram is performed while you are not on your period. It is also more optimal to perform the test during the first part of your cycle after your period ends as opposed to later in your cycle when the uterine lining is thicker.

How is a sonohysterogram performed?

First an ultrasound is performed to visualize the pelvic organs (uterus, cervix, ovaries). Then a speculum is placed to hold the vagina open. A small catheter is threaded into the vagina, past the cervix, and into the uterus itself. Then saline fluid is infused into the uterus until the cavity is distended. While the uterus is being filled, the ultrasound is providing the images that aid in diagnosing various uterine problems such as fibroids, polyps, scarring inside the uterus, or uterine structural anomalies.

What can I expect after a sonohysterogram?

Typically, a sonohysterogram is a very low risk procedure. Post-procedure symptoms include bleeding, cramping, and watery discharge.
