The physician will document that your tubes and uterus are free of obstruction with a hysterosalpingogram. This procedure is conducted at the hospital radiology department as an outpatient procedure.
A small catheter is used to inject die into the uterus. The movement of the dye is monitored by X-ray from the uterus through the fallopian tubes. If there is a tubal blockage, it is seen as a “collection of dye” which appears as a “white mass” before the blockage and very little dye is seen past the blockage. The shape, length, and condition of the fallopian tubes can be assessed.
The HSG also allows visualization of the inside of the uterus making polyps, fibroids, adhesions, or congenital abnormalities visible.
