What is sonohysterography?
Sonohysterography is a technique in which fluid is injected through the cervix into the uterus, and ultrasound is used to make images of the uterine cavity. The fluid shows more detail of the inside of the uterus than when ultrasound is used alone. The procedure can be done in a health care provider’s office, hospital, or clinic. It usually takes about 15 minutes.
Sonohysterography can find the underlying cause of many problems, including abnormal uterine bleeding, infertility, and repeated miscarriage. A sonohysterogram may be ordered when a woman has had a normal ultrasound exam but is still having symptoms. This procedure can detect the following conditions:
Sonohysterography also is done before and after some surgical procedures.
The procedure will be scheduled when you are not having your menstual period. If you are bleeding, the results may not be as clear. The test may be postponed until the bleeding stops. The procedure is not done if you are or could be pregnant, or if you have a pelvic infection or pelvic inflammatory disease. You may be given a urine test to rule out pregnancy.
Sonohysterography is done when your bladder is empty. You will be asked to undress from the waist down and lie on an exam table. Your health care provider may do a pelvic exam to check if you have any tenderness or pain. In some situations, you may be given antibiotics.
Sonohysterography has two parts. A transvaginal ultrasound exam is done first. Next, a fluid is injected through the cervix into the uterus, and an ultrasound exam is done again.
