A sonohysterogram is a transvaginal ultrasound that is performed to diagnose possible causes for abnormal bleeding, infertility, or other conditions. This exam is usually performed at a specific point in a woman's cycle. You will receive specific information and instructions prior to your scheduled appointment. Using a speculum, a thin, flexible plastic catheter will be inserted through the vagina and cervix into the lower part of the uterine cavity. The speculum is then carefully removed, and a vaginal ultrasound probe is placed into the vagina. Through the catheter, a small amount of saline (sterile salt water) is injected into the uterine cavity to separate the walls. The saline solution allows better visualization of the uterine walls and possible irregularities such as polyps or fibroids. Your physician will discuss any abnormal findings with you, and develop an appropriate plan of care.
