Hysterosalpingography is an x-ray of the uterus and fallopian tubes that involves the injection of dye through the cervix.

The exam takes place in a radiology department using a table with an x-ray machine overhead. You will lie on the table and place your feet in stirrups, like a pelvic exam. A speculum is placed into the vagina, and the cervix is cleaned.

A thin tube (catheter) is placed the cervix. Dye passes through this tube, filling the uterus and fallopian tubes. The dye makes the structures easier to see when the x-rays are taken.

Due to a risk of infection, you will be prescribed antibiotics to take before and after the procedure. Your health care provider may also supply sedatives to help you relax during the procedure. Be prepared to sign a consent form before the test begins and to wear hospital clothing. Often the test will be scheduled in the week following your period, to ensure that you are not pregnant during the test.

Inform your health care provider of any allergic reactions to contrast dry you may have had in the past.

You need not limit any foods or fluids prior to the test.

The test feels much like a vaginal examination associated with a Pap smear. You may have menstrual-type cramping during or after the test. You may experience some pain if the dye leaks into your abdominal cavity.
