Fallopian tube blockage is a common cause of infertility. The egg cannot meet sperm if your fallopian tube is blocked. If you are trying to get pregnant, it is always recommended to test your fallopian tubes and make sure your tube is healthy.
We can check your fallopian tube and uterine cavity by using:
Saline infusion salpingogram (SIS) under ultrasound or Hysterosalpinogram (HSG) under X-ray
How is a SIS or HSG done?
Both SIS and HSG are straightforward procedures lasting about 5-10 minutes.
During SIS, we place a speculum in your vagina, clean your cervix and place a very thin cannula into the opening of the cervix. Through the cannula, we gently fill the uterus with a small amount of normal saline and tiny air bubbles. As the normal saline travels through the cervix into the uterus and the fallopian tubes, it outlines the uterine cavity and the fallopian tubes. If a woman has open fallopian tubes, normal saline can spill out the ends of fallopian tubes and can be noted under the ultrasound. You will have the SIS results right away after the procedure.
Similar to SIS, the HSG procedure injects a dye contrast instead of normal saline into your uterine cavity through the thin cannula. The dye contrast can be seen by X-ray during HSG procedure.
Depending on the uterine position, some women might need HSG to assess their fallopian tubes.
