Hysterosonography

Hysterosonography, also known as saline infusion sonography (SIS), is a specialized form of ultrasound used to visualize the interior of the uterus. This non-invasive procedure is often used to diagnose abnormalities in the uterine cavity, such as uterine fibroids, polyps, or endometrial atrophy.

Procedure

Hysterosonography involves the injection of a sterile saline solution into the uterus during an ultrasound examination. The saline expands the uterine cavity, providing a clear view of the interior walls of the uterus and the endometrial lining. The procedure is typically performed in the early proliferative phase of the menstrual cycle, when the endometrial lining is thinnest.

Uses

Hysterosonography is primarily used to investigate the cause of abnormal uterine bleeding. It can also be used to evaluate unexplained infertility, recurrent miscarriage, or abnormal findings from a routine pelvic ultrasound. It is particularly useful in detecting submucosal fibroids and endometrial polyps, which can be missed by traditional ultrasound.

Risks and Complications

While hysterosonography is generally considered safe, there are potential risks and complications. These may include infection, allergic reaction to the saline solution, or puncture of the uterus. However, these complications are rare.
