What is a sonohysterogram (SIS)?

A sonohysterogram (SIS) is a special kind of ultrasound that lets your healthcare provider see inside your uterus  and uterus lining (endometrium) that may be causing unwanted symptoms like bleeding, pelvic pain and infertility.

Why would someone need a sonohysterogram?

A 3D Saline Infusion Sonohysterogram (SIS) is performed at Advanced Sonograms office in Anchorage, Alaska. It is less invasive than other surgical procedures and it does a better job providing detailed views of structures inside your uterus that may be causing symptoms like pelvic pain, unexplained bleeding or infertility.

Your provider may ask you to get a sonohysterogram if these symptoms exist:

  • Your periods are heavier or longer-lasting than is typical.
  • You have vaginal bleeding in between periods.
  • You’ve got pelvic pain that won’t go away.
  • You’ve been unable to get pregnant.
  • You’ve had two or more miscarriages.

A sonohysterogram can reveal these types of structures and conditions:

  • Polyps.
  • Fibroids.
  • Atypical uterus shape.
  • Signs of endometriosis.
  • Signs of endometrial cancer.
  • Blockages in your fallopian tubes.

How do I prepare for a sonohysterogram?

There are time frames and general restrictions on when the imaging can be scheduled and performed.  Your care provider will help to be sure the time is right for the procedure.
