Saline Infusion Sonography (SIS) | Uterine Cavity Assessment at NESA
What Is Saline Infusion Sonography?
Saline Infusion Sonography (SIS), also known as saline sonohysterography, is a specialized ultrasound that provides a clearer and more detailed view of the uterine cavity. A routine scan uses ultrasound waves for visuaising th internal organs. A special USG transducer detects the echoes from the waves that bounce off the surface of the organs and soft tissues. But since the inside of the uterus cavity is filled with fluid, any abnormalities inside the uterine cavity cannot be differentiated in a 2D ultrasound. A SIS involves gently introducing sterile saline into the uterus, which helps highlight the inner lining and reveal even subtle abnormalities.
Why is it done?
SIS is a diagnostic ultrasound technique designed to assess the uterus in greater detail. By filling the uterine cavity with a saline solution, the procedure separates the cavity walls and offers a clear contrast during imaging. This allows doctors to identify issues that might be missed on a standard pelvic ultrasound.
When is it done?
Saline Infusion Sonography is typically recommended when you experience irregular bleeding, infertility concerns, or abnormal ultrasound results. The procedure helps detect:
- Uterine fibroids or muscular growths
- Endometrial polyps
- Scar tissue or adhesions
- Congenital uterine anomalies
- Endometrial thickness irregularities
Accurate diagnosis through SIS helps guide treatment decisions, fertility planning, and overall uterine health management.
What to Expect During the Procedure
The procedure is simple, safe, and minimally invasive. It is usually performed after menstruation but before ovulation for best visibility.
- You will lie comfortably while a thin catheter is gently inserted into the uterus.
- Sterile saline is slowly introduced to fill the cavity.
- A transvaginal ultrasound is performed simultaneously to capture detailed images.
- The process usually takes about 15–20 minutes and causes only mild discomfort in most women.
There’s no recovery downtime—you can resume your normal routine immediately afterward.
