Hysterosalpingogram (HSG)

The hysterosalpingogram (HSG) is an x-ray evaluation performed at the outpatient surgery department of the hospital. In the HSG, a radio opaque dye is injected into the uterus and sequential x-rays are taken as the dye travelsthrough the uterus and fallopian tubes. This test is typically performed between cycle days six and ten.

If there is a blockage of the fallopian tubes, it shows as a collection of the dye at the point of the obstruction. The dye also shows the size and shape of the uterus.

HSG, Overview

1. On the first day of your menstrual cycle, call and schedule the HSG. The HSG is done after your period and before ovulation, usually between cycle days 6 and 10. (Note: After scheduling the test, notify us if your period is abnormal in any way.)
2. Please check with your nurse concerning the medications you can take prior to the HSG. In general, you may take ibuprofen 600 mg or similar over the counter pain medications.
3. You will be at the hospital for approximately 1.5 hours and the actual procedure takes about thirty minutes.
4. The physician will insert a speculum into the vagina followed by a small catheter that will be used to inject the dye into the uterus. You will be asked to roll from side to side so that the dyes passage can be observed and x-rays taken. You may experience “menstrual like” cramping.
5. After 15 minutes, two delayed x-rays may be taken to insure that the fallopian tubes are completely open.
