Hysterosonography, also called sonohysterography, uses sound waves to produce pictures of the inside of the uterus and help diagnose many problems, including unexplained vaginal bleeding, infertility, and repeated miscarriages.
Hysterosonography is performed very much like a gynecologic exam. Your doctor will insert a speculum into your vagina and insert a catheter into the cavity of the uterus. 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-rays.
It is best to perform hysterosonography immediately after your period and within 10 days after the first day of your period to minimize the risk of infection and unintended loss of a very early pregnancy.
