Hysterosalpingogram (HSG) is a fluoroscopic examination of the uterus and the Fallopian tubes, most commonly used in the investigation of infertility or recurrent spontaneous abortions.

  • Infertility to assess uterine morphology and tubal patency.
  • pregnancy
  • active pelvic infection
  • recent uterine or tubal surgery
  • the procedure should be performed during the proliferative phase of the patient’s menstrual cycle (days 6-12), when the endometrium is thinnest 
    • this improves visualization of the uterine cavity, and also minimizes the possibility that the patient may be pregnant 1
    • if there is any uncertainty about the patient’s pregnancy status, a beta hCG is warranted prior to commencing.
  • after an antiseptic cleaning of the external genital area, a vaginal speculum is inserted with the patient in the lithotomy position; the cervix is cleaned with an aseptic solution.
  • catheterization of the cervix is then performed; the type of device used depends on local practice preferences
  • whatever the device, it should be primed with contrast prior to commencing to avoid the introduction of gas bubbles which may provide a false positive appearance of a filling defect.
  • water soluble iodinated contrast is subsequently injected slowly under fluoroscopic guidance.
  • some radiologists use iodinated oil (Lipiodol) as contrast when the indication is for lack of fertility. Some authors report increased fertility after its use: this remains controversial however 8.
  • a typical fluoroscopic examination includes a preliminary frontal view of the pelvis, as well as subsequent spot images that demonstrate uterine endometrial contour, filled Fallopian tubes and bilateral intraperitoneal spill of contrast, to establish tubal patency.
  • pelvic infection
  • contrast reaction
