1, the process of imaging: 1, do not have intercourse after menstruation, after the clean menstruation (Shanghai patients) or the 2-3 days after the clean menstruation (foreign patients can reduce the number of trips to Shanghai) to see the clinic, laboratory tests routine white belt (immediately can see the results), normal, that is, you can open an application form to book an appointment for imaging (HSG), the cost of a little more than 7 hundred, plus the cost of the water together in about 8 hundred. 2.HSG is usually scheduled to be done on the 3rd-7th day after menstruation (before ovulation). The HSG procedure usually takes about 5 minutes, and the contrast done in our hospital is basically painless, only a little bit of soreness and swelling when playing the contrast agent. Precautions after HSG: (1) No intercourse or bathing for 2 weeks after the procedure; (2) Take oral antibiotics for 3-5 days; (3) Pick up the report from the service desk in the outpatient clinic lobby after 2 working days. If you need an imaging film, you need to pick up the film from the radiology department after getting the report. (4) Both hospitals are connected by PACS, so you can pick up the report and film from each other (warm tip: you don’t need to go to the other hospital to pick up the report or film in order to see the outpatient clinic, so as to reduce unnecessary running around). 5. The fastest – you can try to conceive in the next menstrual cycle after the tubal angiography. II. Procedure of HSG operation: As iodine water is easily absorbed, the side effects are small. It is especially important to take a delayed film as a proof to assess the patency of the fallopian tubes. The delayed film is particularly important as a proof of tubal patency. If iodine oil is used as the contrast agent, the delayed film should be taken again after 24 hours because of the slow dispersion of iodine oil. 6. The importance of standardized HSG examination: Although there are many hospitals that can do tubal imaging, not many can really do it well. Many patients pass the film and half of them fail, either because they did not delay the film, or the interval between delayed films is too short, or the drug given is not enough, or the contrast tube is not in place, or the uterine horn is blocked when the tube is inserted causing pseudo-inaccessibility of the fallopian tube, or the timing of the capture may not be right causing the fallopian tube to be poorly visualized. Therefore, it is easy to do the imaging but difficult to do it well. If the hospital where the patient is seen and the doctor who does the imaging happen to be not very professional, it will be easy to misdiagnose the problem and since the diagnosis is wrong, the direction of treatment will definitely be wrong. The actual fact is that you will be able to find a professional doctor in the regular hospital who is very specialized in tubal examination, otherwise you will spend money and suffer from delay. The key to tubal treatment is to do tubal imaging, another key is the reading of the film.
