Hysterosalpingography (HSG) is a fluoroscopic X-ray study of a woman's uterus and fallopian tubes. It involves insertion of a catheter into the cervix and instillation of a water soluble contrast material into the uterus and fallopian tubes.
Any woman who is pregnant, or thinks she might be, should let her doctor know before proceeding with the exam.
What to expect during the HSG?
The obstetrician/gynecologist performs the study with fluoroscopic assistance from the radiologist. The study usually is completed within 30 minutes.
While lying on the X-ray table the obstetrician or gynecologist will place a speculum into the vagina, clean the cervix, and then insert a catheter into the cervix. The speculum is then removed. Contrast material is then slowly instilled to fill the uterine cavity, fallopian tubes and peritoneal cavity. As this occurs, fluoroscopic X-ray images are taken. These images are promptly reviewed and the catheter removed.
There may be slight discomfort and cramping when the catheter is placed and contrast material injected, but it should not last long. There may also be slight generalized lower abdominal pain, but this should also be minimal and not long lasting. Most women experience vaginal spotting for a few days after the examination, which is normal.
