sonohysterogram alaska


Sonohysterography (or Saline Infusion Sonography) is a specialized technique used to obtain extremely detailed images of the uterine cavity. The procedure is performed by a physician gynecologist. A thin catheter is passed through the cervix into the uterine cavity. Transvaginal imaging is performed as sterile saline is gradually injected into the uterine cavity. This allows demonstration of any structural abnormalities of the uterine cavity. Three dimensional images are obtained to provide additional details.

Several common indications for a 3D sonohysterogram:

  • Infertility
  • Abnormal vaginal bleeding
  • Endometrial Polyps
  • Congenital uterine anomaly
  • Equivocal findings on standard pelvic sonogram

What to Expect

You will be lying on a gynecologic exam table, completely draped from the waist down. A gynecologist will utilize a speculum similar to what is used during a routine pap smear. The cervix is localized and cleansed using betadine or an equivalent solution. A thin catheter is then passed through the cervix and into the uterine cavity. At this point the speculum is removed and the transvaginal probe is inserted. A small balloon located near the tip of the catheter is then expanded using less than 1 ml of saline. Mild cramping may be experienced at this time. The balloon is moved into position and sterile saline gradually injected until adequate distension of the uterine cavity is achieved. Cramping is typical at this time but is usually mild in severity. Once adequate images are obtained, usually taking less than 5 minutes, the balloon is deflated and catheter withdrawn.

The transvaginal transducer is covered with a NON-LATEX sheath.

How is the Transvaginal Probe Disinfected?

We use the latest advancement in High Level Ultrasound Transducer Disinfection. Trophon EPR is an automated system that is the most effective, safest and environmentally friendly method to disinfect ultrasound transducers. View this video to learn more:

Exam Preparation

No prep is necessary for this examination. If you anticipate discomfort with the procedure, an over the counter pain reliever may taken prior to the examination.

If your bladder becomes unbearably full while waiting for your exam, it is ok to partially empty your bladder to relieve pressure.
