Saline Infusion Sonohysterogram

Your First Visit

Patient Instructions for Sonohysterogram (SHG)

Dr. John Nichols, Dr. John Payne of Piedmont Reproductive Endocrinology Group (PREG) or your referring fertility specialist has ordered a Sonohysterogram as part of your infertility treatment and evaluation plan. It is a valuable procedure for examining the inside of the uterus or womb (endometrial cavity).


Please call the office at 864.232.7734 to set up your Sonohysterogram when your menstrual period starts. If your period starts on the weekend, please call us on the following Monday. Your Sonohysterogram will typically be scheduled for the following week (cycle day 6 through 11). If you are presently on oral contraceptives (birth control pills) your Sonohysterogram can be scheduled for any day that you are not bleeding.

Most patients tolerate this procedure very well. Some women have a small amount of cramping. Some patients prefer to take medication for cramps prior to a Sonohysterogram. We recommend:
– Ibuprofen (Advil or Motrin), 2 tablets (200 mg per tablet), or
– Acetaminophen (Extra Strength Tylenol), 2 tablets (500 mg per tablet).


A speculum is placed in the vagina and the cervix is then cleaned with an antiseptic solution (Betadine). A small catheter is gently introduced into the cervical canal. A saline solution (salt water) is then put into the uterus through the catheter while looking at the uterus with the ultrasound probe. When the procedure is finished, the speculum and catheter are gently removed.

You may experience slight pressure and/or cramping during insertion or removal of the catheter, or during infusion of the saline solution.

Once the procedure is completed you will discuss your findings as well as the appropriate follow-up treatment with your physician.

After Your Sonohysterogram

You may have some cramping, spotting or bleeding, or watery discharge for several days. Please call the office at 864.232.7734 if you experience any of the following:

  • Severe abdominal pain
  • Heavy bleeding (more than a period)
  • Foul – smelling discharge
  • Fever

Who should not get a Sonohysterogram

  • If there is any evidence of any vaginal, cervical or pelvic infection.
  • If you are actively bleeding at the time of your procedure.
