Sonohysterography, uses sound waves to produce pictures of the inside of a woman’s uterus and help diagnose unexplained vaginal bleeding. Hysterosonography is performed very much like a gynecologic exam and involves the insertion of the transducer into the vagina after you empty your bladder. Using a small tube inserted into the vagina, your doctor will inject a small amount of sterile saline into the cavity of the uterus and study the lining of the uterus using the ultrasound transducer. Ultrasound does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don’t show up well on x-ray images.
It is best to perform Sonohysterography one week after menstruation to avoid the risk of infection. Little or no special preparation is required for this procedure. Inform your doctor if there’s a possibility you are pregnant. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.
