Hysterosalpingogram

Description and Purpose

An Hysterosalpingogram (also referred to as hysterogram , hysterosalpingography , uterography , uterotubography , and uterosalpingography ), is a procedure where radiopaque contrast dye is used to highlight the reproductive tract while being X-rayed. The aims of this procedure include:

Preparation and Procedure

The test will be scheduled during the early part of the menstrual cycle (between menstruation and ovulation), when pregnancy is unlikely. This is due to the fact that this test should not be carried out on a pregnant woman.
An X-ray machine is suspended over the abdomen and a speculum is inserted into the vagina to hold it open. Then a thin, grasping instrument called a tenaculum is inserted to hold the cervix in place.
A thin catheter is inserted through the cervix into the uterus and radiopaque contrast dye is instilled through the catheter. This usually causes several minutes of cramping and may result in spasm.
The gynaecologist and radiologist watch the dye on a fluoroscope screen as it enters the uterus and spreads through the fallopian tubes, looking for abnormalities. 4 to 8 X-rays are taken at various intervals as the dye travels through the reproductive tract.
A variation of this technique is the sonohysterogram , where a catheter is inserted into the uterine cavity to instil fluid to distend the uterus, which is then examined via transvaginal ultrasound for space-occupying structures.
