Saline-infusion sonohysterography (or hysterosonography) is a procedure that allows a more detailed view of the inner lining of the uterus (endometrium) than is possible with standard pelvic ultrasound. This is achieved by filling the uterine cavity with sterile salt water through a thin plastic catheter that is placed at the cervix and then taking ultrasound images. The water outlines any polyps or tumors of the endometrium that may be present. The number and location of polyps are easily assessed, which is information that can guide the gynecologist when performing a D&C procedure.

Situations when sonohysterography can be useful include abnormal vaginal bleeding, heavy periods, and a thickened or abnormal-appearing endometrium on standard pelvic sonography. 

Please contact us with any questions.

This sonohysterogram image shows two polyps (asterisks) nicely outlined by the saline (S) that was introduced into the uterus during the procedure.
