Radiation Exposure - Radiation exposure from an HSG is very low, less than with a kidney or bowel study.Fainting - Rarely, the woman may get light-headed during or shortly after the procedure.A woman should call her doctor if she experiences increasing pain or a fever within 1-2 days of the HSG. In rare cases, infection can damage the fallopian tubes or make it necessary to remove them. This usually occurs when a woman has had previous tubal disease (such as a past infection of chlamydia). Infection - The most common serious problem with HSG is pelvic infection.However, there is a set of recognized complications, some serious, which occur less than 1% of the time. What are the risks and complications of HSG? However, most doctors perform HSG only for diagnostic reasons.
Some studies show a slight increase in fertility lasting about 3 months after a normal HSG. It is controversial whether this procedure enhances fertility. Does a hysterosalpingogram enhance fertility? Women should be prepared to have a family member or friend drive them home after the procedure in the event that they are experiencing cramping. These symptoms can be greatly reduced by taking medications used for menstrual cramps before the procedure or when they occur. However, some women may experience cramps for several hours. Is it uncomfortable?Īn HSG usually causes mild or moderate uterine cramping for about 5-10 minutes. After the HSG, a woman can immediately return to normal activities, although some doctors ask that she refrain from intercourse for a few days. Often, side views of the uterus and tubes are obtained by having the woman change her position on the table. The HSG procedure is not designed to evaluate the ovaries or to diagnose endometriosis, nor can it identify fibroids that are outside of the endometrial cavity, either in the muscular part of the uterus, or on the outside of the uterus. Abnormalities inside the uterine cavity may also be detected by the doctor observing the x-ray images when the fluid movement is disrupted by the abnormality. As the contrast enters the tubes, it outlines the length of the tubes and spills out their ends if they are open.
The contrast will be seen as white on the image and can show the contour of the uterus as the liquid travels from the cannula, into the uterus, and through the fallopian tubes.
The doctor gently fills the uterus with a liquid containing iodine (a fluid that can be seen by x-ray) through the cannula. Her cervix is cleaned, and a device (cannula) is placed into the opening of the cervix.
The gynecologist or radiologist then examines the patient’s uterus and places a speculum in her vagina. How is a hysterosalpingogram done?Ī woman is positioned under a fluoroscope (a x-ray imager that can take pictures during the study) on a table. It is usually done after the menstrual period ends but before ovulation. HSG is an outpatient procedure that usually takes less than 5 minutes to perform.
