Saline Sonography

Saline sonography, also known as saline infusion sonohysterography (SIS or SHG), is a specialized ultrasound technique used to evaluate the uterus. During this procedure, a small amount of sterile saline solution is gently infused into the uterine cavity through a thin catheter while transvaginal ultrasound imaging is performed.

The infusion of saline helps to expand the uterine cavity, providing a clearer view of the endometrial lining and allowing for more detailed visualization than standard ultrasound alone. This enhanced detail can help detect abnormalities such as polyps, fibroids, adhesions, or abnormal uterine shapes that might be contributing to symptoms like abnormal uterine bleeding, infertility, or recurrent pregnancy loss.

Saline sonography is generally well-tolerated, minimally invasive, and does not require anesthesia. Some women may experience mild cramping during or after the procedure. It is usually performed in the first half of the menstrual cycle, after menstruation but before ovulation, to avoid interfering with a potential early pregnancy.

It is an important tool in gynaecological evaluation, providing valuable information for both diagnosis and treatment planning.
