A tubalogram is usually mildly painful, but the vast majority of people can tolerate it. Tubalography is a test used to check the patency of a woman’s fallopian tubes. During a tubalogram, a tube is placed in the endocervix and iodized water or iodized oil is injected into the uterus, where the contrast agent passes through the uterine cavity into the fallopian tubes, where it is visualized on an X-ray. If the woman’s fallopian tube is open and the doctor is skillful, there is usually no very obvious pain. If the fallopian tube is not open and the doctor is not skillful enough, the patient may feel uncomfortable, but the pain is usually not severe and within the tolerable range. If the doctor is not skillful during the operation, or if the fallopian tube is not open enough, and the entry of the contrast medium into the fallopian tube is blocked, there may be pain. However, this pain will not be too intense, and may be similar to the degree of lower abdominal pain and distension during menstruation, which can be tolerated by patients in general.
