HSG/Saline Sonohysterogram

Hysterosalpingogram (HSG)

The hysterosalpingogram, or HSG, is an X-ray of the uterus and fallopian tubes. The procedure is done at the radiology department and involves injecting a contrast dye into the uterus. It is usually performed after menstrual bleeding has ended and before ovulation occurs. The timing of the procedure allows for optimal viewing of the uterine cavity and the fallopian tubes. At the time of the test, a special catheter is placed through the vagina and into the cervix. X-ray pictures are then taken as the contrast medium passes through the uterus and this contrast medium will continue out the ends of the fallopian tubes, if they are open. This test helps to determine if the cavity of the uterus is normally shaped and if the tubes are open. It is a short procedure usually taking only 10 to 15 minutes. A second X-ray may be taken one hour after the initial procedure.
During the procedure, you may experience some mild menstrual-like cramps and feel slightly dizzy. Many patients have mild cramping and light bleeding for a day or two after the procedure. These symptoms are normal and are relieved with Tylenol or other nonsteroidal anti-inflammatory agents. If you are allergic to X-ray contrast dye, iodine or shellfish, you may be allergic to the dye used for the HSG. If you develop hives, shortness of breath or a rash, you should tell your nurse or doctor as soon as possible.

Saline Sonohysterogram

The saline sonohysterogram is a sonogram performed while a saline solution is being injected into the uterus. It is also called: Saline Ultrasound, Saline Sonogram, Hysterosonogram, Saline Infusion Sonogram (SIS), or Saline Infusion Sonohysterography.

The sonohysterogram is usually performed after menstrual bleeding has ended and before ovulation occurs. The timing of the procedure allows for optimal viewing of the uterine walls, since they are at their thinnest at this point in a woman’s cycle. But this timing may vary depending on what type of investigation it is intended for. We routinely perform saline sonohysterogram in our office by our physicians. This allows our physicians to evaluate the uterus for possible causes of infertility, recurrent miscarriage, or abnormal bleeding.

During the examination, the physician inserts a speculum into the vagina as if performing a Pap smear and a very thin catheter is inserted through the cervix into the uterus. This will be followed by insert a transvaginal ultrasound wand and injection of small quantity of a saline solution through the catheter. The entire procedure can be completed within 5-10 minutes. Some patients have mild cramping and light bleeding after the procedure but the symptoms resolve shortly after completion of the examination. These symptoms are normal and are relieved with Tylenol or other nonsteroidal anti-inflammatory agents.
