Sono-Hysterosalpingography - "Sono-HSG"

The "sono-HSG" is an ultrasound exam to study the contour of the uterine cavity and the patency of the fallopian tubes. The exam is performed here in our office by Dr. Russell and an assistant.
There is no special preparation needed for the exam. You may want to empty your bladder prior to the test. A speculum will be inserted into the vagina to visualize the cervix. The cervix is then cleaned with a betadine solution. (Please make us aware if you are allergic to shellfish or iodine). A thin tube is inserted into the cervix and a balloon on the tube is inflated to hold the tube in place. Saline solution is injected through a syringe into the uterus and fallopian tubes and is visible on the ultrasound screen.
When the uterus fills with the saline, the fluid will flow through the tubes and out the opening at the distal portion (end) of the tubes. The fluid will end up in the abdominal cavity where it will be reabsorbed. Cramping may occur during the procedure if there is any resistance to the flow of saline through the fallopian tubes.
If the saline solution does not flow easily through the tubes, tubal disease may be present. The blockage can interfere with the fertilization process and may be contributing to your infertility.
If the saline flows freely through the fallopian tubes, this will indicate that there is a passageway for the sperm to meet the egg and begin the fertilization process. Healthy, open tubes enable the embryo to travel safely to the uterus.
You may experience some discomfort with this procedure. You may take Tylenol, Advil or Motrin one hour prior to the procedure to decrease any cramping which may occur. This procedure is performed between cycle day 5-12, cycle day 1 is the first day of full flow of your menstrual cycle.
