October 20, 2023

When it comes to diagnosing and treating various gynecological conditions, medical advancements have paved the way for less invasive and more accurate procedures. 

Saline Infusion Sonohysterography (SIS), also known as sonohysterography, is one such procedure that has revolutionized the way doctors evaluate the uterine cavity and identify potential issues. In this blog, we will discuss what sonohysterography is, the procedure, its indications, and its importance.

What Is Sonohysterography?

Sonohysterography is a diagnostic imaging technique that combines ultrasound with saline infusion to provide a detailed view of the uterine cavity. This procedure is commonly used to evaluate and diagnose various gynecological conditions, such as fibroids, polyps, adhesions, and abnormal bleeding. The term "sonohysterography" is derived from "sono" (ultrasound) and "hystero" (uterus), highlighting its focus on the uterine cavity.

Saline Infusion Sonohysterography Procedure

The SIS procedure involves the following steps:

  • Preparation: Before the procedure, patients are typically advised to schedule the test during a time when they are not menstruating. This helps in obtaining a clearer image of the uterine cavity. Some doctors may prescribe a pain reliever to alleviate potential discomfort.

  • Ultrasound: A transvaginal ultrasound probe is inserted into the vaginal canal to capture images of the uterus. This initial ultrasound helps establish a baseline image of the uterine cavity.

  • Saline Infusion: A small, flexible catheter is then inserted through the cervix into the uterine cavity. Sterile saline solution is slowly injected into the uterus through this catheter. The saline inflates the uterine cavity, allowing for better visualization of the uterine walls.

  • Image Capture: As the saline fills the uterine cavity, the ultrasound probe captures real-time images. This dynamic imaging helps the healthcare provider to identify any abnormalities, such as polyps or fibroids, that may be present.

  • Post-Procedure: After the procedure, the catheter is removed, and patients are usually able to go about their day as usual. Discomfort is typically minimal, and any mild cramping should subside within a short time.

However, you must consult your doctor if you experience severe pain or fever. Also, inform your doctor about any change in the amount or type of vaginal discharge. It can be a sign of an infection.

  • Infertility Diagnosis: SIS can help identify abnormalities in the uterine cavity that may be contributing to infertility.
  • Uterine abnormalities: It can also be used for further diagnostics  of certain uterine abnormalities detected by standard transvaginal ultrasound or in case endometrium can’t be assessed well with standard exam.
  • Recurrent pregnancy loss: Sonohysterography can be also an effective tool to assess uterine cavity defects associated with recurrent pregnancy loss.

Why SIS Sonohysterography?

Saline Infusion Sonohysterography offers numerous advantages, including:

  • Non-invasive: Unlike traditional diagnostic procedures, such as hysteroscopy, SIS is non-invasive and typically causes minimal discomfort.
  • Accurate Diagnosis: SIS provides detailed images of the uterine cavity, making it easier to identify and diagnose various conditions.
  • Outpatient Procedure: SIS is often performed in an outpatient setting, making it convenient for patients.
