Patient's question:
Does tubal contrast hurt? I've been married for two years and haven't been able to get pregnant, so I went to the hospital for a check-up. The doctor said I need to have tubal contrast. Does tubal contrast hurt? What do I need to pay attention to?Doctor's answer:
Hysterosalpingography (HSG) is an X-ray examination of the uterus and fallopian tubes using iohexol as the contrast agent. HSG is a method to check how the fallopian tubes are (patent), blocked, and the shape of the uterine cavity. It is implemented by injecting anesthetized iohexol contrast into the uterine cavity and fallopian tubes through a catheter, followed by X-ray scanning and photography for confirmation. The instrument was developed based on the expansion of the contrast agent in the fallopian tubes and pelvic cavity. Its application range is safe, with no side effects and certain therapeutic effects. It can be performed 3-7 days after menstruation, generally without pain.
