The HSG is a procedure in which a special type of x-ray using a fluoroscope is taken of the uterus and fallopian tubes after a radio-opaque dye is introduced into the uterus through the cervix.
This procedure outlines the interior contour of the uterus and determines if the fallopian tubes are open (tubal patency) or if after an Essure procedure, identifies the satisfactory placement of the Essure micro-inserts within the tubes. If performed after an Adiana procedure, the HSG will note if the tubes are open or appear occluded by x-ray.
You will be asked to undress completely from the waist down. A speculum is then placed into the vagina and the cervix is cleansed with an antiseptic (Betadine or Hibiclens). After the cervix is cleansed, local anesthetic (Lidocaine) is used to numb the cervix prior to placement of an instrument which holds the cervix in position. Rarely, one may feel a slight pinch and a 2 second burn from the injection, however, the majority of women feel nothing. You will not feel any discomfort from the instrument being placed on the cervix. At this point, another instrument (cannula) is then placed 1 cm into the cervical canal and radio-opaque contrast dye is injected slowly into the uterus. Some women may experience some discomfort similar to light menstrual cramps as the dye enters the uterus, however, the majority do not. X-rays will be taken as the dye fills the uterus and the fallopian tubes. After the procedure is completed, based on your preference, a tampon can be inserted, or you may use a pad, since some of the contrast will leak out into the vagina. While the contrast dye itself is clear, you can expect to have some spotting over the next few days as result of the instrument placed on your cervix. The entire procedure is usually completed within 5 minutes. We recommend you abstain from intercourse for 24-48 hours after the HSG in order to minimize any risk of infection.
