What Is A Sonohysterogram? 3 Reasons Your Doctor May Order An SHG

Getting A View Of Your Uterus

A sonohysterogram (SHG), also called a saline infusion sonogram (SIS), is a technique that allows viewing of the inside of the uterus. In this procedure, a saline fluid is inserted into the uterus through a catheter. While the fluid is inside, the ultrasound allows visualization of the structures of the uterus. SHG helps the doctor to check for any abnormality within the uterus or uterus lining, ovaries, and fallopian tubes.


1. Abnormal vaginal bleeding

There are many reasons for the healthcare specialist to order an SHG test. One common reason the doctor may recommend an SHG is abnormal vaginal bleeding. Abnormal vaginal bleeding includes heavy bleeding than normal, a longer duration of bleeding, and bleeding between periods.

2. Abnormal pelvic condition

The doctor may recommend an SHG if there is an abnormal pelvic exam. Additionally, a patient experiencing unbearable pelvic pain that does not subside will require an SHG. Intolerable pelvic pain can occur due to conditions like endometriosis, uterine fibroids, or uterine cancer.

3. Unexplained infertility issues

Couples who are trying to conceive and experiencing fertility issues may need an SHG. Women who are unable to get pregnant or are having recurrent miscarriages will need an SHG to examine the uterus. This will help to determine the cause of infertility and what further action is needed.

Diagnosing medical conditions

An SHG helps to view the internal structures of the uterus to check for abnormalities. This imaging technique can help to diagnose many medical conditions. Some common conditions include endometriosis, fibroids, polyps, uterine cancer, obstruction of fallopian tubes, and abnormal uterus shape. Any internal scarring of the uterus or uterine lining irregularities can also be distinguished with an SHG.

Candidates who are excluded

A healthcare provider may order an SHG after taking a medical history and examination. However, not everyone is suitable for this procedure. Women who are pregnant or have pelvic inflammatory disease are excluded from this imaging procedure.

Expectations after an SHG

After the procedure, one can go home the same day and may expect some mild symptoms. Mild symptoms include cramping, light spotting, and watery vaginal discharge. Pain is not common but one can take over-the-counter pain medications. After an SHG, one recovers quickly and can return to daily activities. Speaking to the doctor about resuming certain activities like intercourse is advisable.

When to call a doctor

Serious side effects after an SHG are uncommon. However, if one experiences severe pain, fever, or changes in vaginal discharge after a few days, call a physician immediately. These signs could mean an infection may have occurred.

Making use of an SHG

Doctors recommend various tests for conditions like unexplained infertility, abnormal bleeding, and abnormal pelvic pain. A doctor may order an SHG to get a better understanding and viewing of the internal structures of the uterus. Saline fluid infusion is necessary to ensure a detailed visualization of the structures. This procedure will help diagnose many gynecological conditions and also help a specialist decide the next step.
