About this study

The hysterosalpingogram (HSG) is the gold standard of assessing fallopian tube patency and involves the placement of a transcervical catheter to allow for instillation of radio-opaque dye into the uterine cavity and fallopian tubes which are then imaged with abdominal x-ray. A common side effect of the instillation of dye is the uterine cramping, which is both uncomfortable for the patient as well as can cause iatrogenic proximal occlusion of the fallopian tubes. Proximal tubal obstruction is often not representative of true tubal obstruction but is rather an artifact of the test. Prior studies measuring the perceived pain and cramping during HSG have been conducted which have shown reduced pain scores and decreased uterine cramping when warmed contrast dye is used. The researchers propose that the use of warmed contrast media during HSG will be correlated with decreased pain scores and fewer cases of proximal tubal occlusion in women with otherwise normal uterine anatomy.
