Ultrasound > Exams & Procedures > Hysterosonogram

A Hysterosonogram is one of the ways to evaluate the inner lining of the uterus, the endometrium. This is a procedure for women who have abnormal or excessive bleeding. It is also used in infertility studies. The endometrium has a double layer, which is usually collapsed upon itself. This examination can assess internal masses such as fibroids or polyps. This procedure allows the radiologist to see between the two layers of the endometrium.

  • The procedure takes about 30 minutes to one hour.
  • It is imperative that this exam be scheduled during the middle (seventh to tenth day) of your menstrual cycle as not to interfere with your menses or interrupt any possibilities of pregnancy.
  • You are asked to take an Advil one hour before your test and another immediately after your test.
  • You may eat regularly prior to the ultrasound exam unless you are also scheduled for an abdominal ultrasound.
  • A speculum is used to locate and open your cervix. This is similar to a papsmear done in your doctor's office.
  • A thin tube or catheter is inserted into your cervix and fixed in position.
  • The speculum is removed and a transvaginal ultrasound probe is inserted into the vagina.
  • Images are taken of the endometrium with and without sterile saline solution.
  • The saline solution immediately spills out of the cervix and your are given cleaning material to dry yourself off.

Transvaginal Ultrasound

A Transvaginal Ultrasound is performed by inserting a narrow probe or transducer into the vagina with your bladder empty. This allows the technologist to see and magnify your uterus and ovaries because the sound waves are closer to the pelvic organs. Therefore, higher resolution images can be obtained especially when assessing the inside of uterus (i.e. endothelial lining and early pregnancies).

Does this hurt?

You may experience some discomfort. The preparation of the procedure feels similar to a pap smear. The injection of saline water into the uterus may cause temporary cramping, similar to that of menstrual cramps. As soon as the fluid is removed the cramping subsides.

When will I get my results?

If you are seeing your doctor immediately after your ultrasound appointment, a hand written report preliminary will be given to you. If you are not seeing your doctor following the ultrasound test, a final report will be mailed to your doctor within seven days.
