Sonohysterogram – SHG – Frisco, TX*

16 Procedures ( View All )


During your visit to Frisco Institute for Reproductive Medicine in one of our clinic locations, we may recommend using a sonohysterogram for diagnostic purposes. Our board-certified reproductive endocrinologists use a sonohysterogram (a transvaginal ultrasound in combination with saline solution) to produce a picture of the uterus to determine what issues might be causing infertility. A sonohysterogram is also used to evaluate unexplained vaginal bleeding by injecting the saline solution into the uterus through a catheter placed in the cervix. Once the saline solution fills and separates the walls to the endometrial cavity of the uterus, a transvaginal ultrasound is used to give a much clearer picture of the uterine cavity than can be obtained from a traditional ultrasound imaging.

Both ultrasound and sonohysterogram use sound waves transmitted through the body to create a real-time picture of what is happening inside the body. But the combination of more precise transvaginal imaging and the saline infusion into the uterine cavity provide superior images. The saline outlines the uterine cavity (endometrium) and makes abnormalities such as endometrial growths or scar tissue much more readily visible. To find out if you qualify for a sonohysterogram or have been referred by another physician, we invite you to call our office in Dallas, McKinney, or Frisco, TX.

Considering a SHG?

When women are having trouble getting pregnant, having recurrent miscarriages, or abnormal abdominal bleeding they may receive a sonohysterogram. This is the next step in finding a more in-depth diagnosis after a traditional ultrasound fails to explain or find the condition impeding pregnancy. A sonohysterogram typically diagnoses uterine adhesions (scarring), an abnormally shaped uterus, and growths or masses, such as fibroids or polyps within the uterus.

SHG Technique

During your appointment time at FIRM, you will lie face up on the exam table with clothing removed from the waist down and legs in stirrups to allow for a better visual of the vagina. Your doctor will insert a speculum into the vagina and guide a catheter through the vagina and cervix into the uterus. Once the catheter is placed, the speculum is removed and the transducer, which converts sound waves into electrical signals and vice versa, is gently placed inside the vagina until it is touching the cervix. A saline solution is injected through the catheter to enlarge the uterus. Your doctor will slowly rotate and reposition the transducer to capture the necessary images. While there is typically minimal discomfort experienced during a sonohysterogram, you may want to take an over-the-counter pain reliever to help with the pain of cramping after the imaging session.

SHG Risks & Benefits

There are no known medical risks from a sonohysterogram. But a woman may experience the following side effects after a sonohysterogram:

  • Mild cramping from the saline solution (over the counter pain medicine should help)
  • Vaginal spotting for the following few days
  • Extremely low chance of perforating the uterus
  • Low chance of infection

A sonohysterogram is helpful in detecting uterine adhesions (scarring), abnormal growths such as fibroids and polyps, and abnormalities in uterine shape or structure. All of these can inhibit fertility and once diagnosed, the appropriate treatment can help a woman regain her fertility. It is less expensive than other reproductive imaging techniques, takes about 10 minutes to perform, and will not expose you to radiation.
