Hysterosalpingogram (HSG)

 Why do I need an HSG? 

The fallopian tubes must be open for an egg to travel from the ovary to the uterus. The uterus must be shaped normally to accept and support a developing embryo. An HSG helps your doctor to determine this.

 What is an HSG? 

The HSG involves injecting an iodine-based contrast media, using a small catheter inserted through the vagina and into the cervix, and monitoring its flow via real-time

X-ray from the uterus through the tubes and into the abdominal cavity. The HSG is an outpatient procedure performed next to our office in the Minor Procedure Suite (MPS). 

 Is an HSG uncomfortable? 

An HSG usually causes mild or moderate uterine cramping for about five minutes. We advise taking 600mg. of Ibuprofen 30 minutes prior to the procedure to minimize cramping.

 What happens if I have an abnormal result? 

If the tubes are blocked, the dye cannot pass and this is visible on x-ray. Sometimes this can be corrected at the time of the HSG. Uterine abnormalities such as polyps, fibroids, or congenital malformations are usually visible in the HSG. Sometimes forcing dye through the tubes will cause them to open or small obstructions might be removed. Consequently, some women may have an increased chance of pregnancy in the months immediately following the HSG.

 What are the risks of an HSG? 

An HSG is considered a very safe procedure. However, a complication may occur less than one percent of the time. The most common complications include infection and fainting. You should notify your physician if you have a fever or increased vaginal discharge after the procedure.

 What can I expect after having an HSG performed? 

Vaginal spotting commonly occurs for one to two days after HSG. Unless otherwise instructed, a patient should notify her doctor if she experiences heavy bleeding after HSG.
