Hysterosalpingography is an examination and treatment method that involves the insertion of a catheter through the cervical canal, injection of contrast medium and radiography, mainly for understanding the uterine cavity and the patency of the fallopian tubes. 1.Procedure method: A special catheter is inserted into the uterine cavity through the cervical canal, and the contrast medium is pushed under positive pressure into the tubes bilaterally to observe the upward flow, reflux and resistance of the fluid, while radiographs are taken to achieve the dual purpose of examination and treatment. 2. Timing of the procedure: within 3-7 days after menstruation, no history of sexual intercourse in this cycle, no contraindication to gynecological examination and routine blood, white belt and ultrasound examination. 3. Risks and complications: The examination requires the insertion of a double-lumen tube into the uterine cavity and the use of some drugs and contrast agents, and the following risks and complications may exist, including (but not limited to): 1) intraoperative and postoperative abdominal pain; 2) intraoperative and postoperative bleeding; 3) uterine perforation and cervical laceration, with laparoscopic or open repair if necessary; 4) occurrence of “vagal syndrome “5) allergy to drugs (contrast) or drugs entering the blood vessels, rash, respiratory distress, pulmonary embolism and shock in severe cases, which can be life-threatening; 6) failure of examination due to cervical scarring, adhesions, tight cervical opening or excessive relaxation of the cervical opening. Failure of the examination. 7) Termination of the test due to serious complications; 8) Due to the inherent limitations of the test, the results do not fully reflect the true condition of the uterine cavity and fallopian tubes. For example, lumpectomy does not really reflect the patency and function of the fallopian tubes or the side of obstruction, and hysterosalpingography also has false positives; 9) postoperative infection and uterine adhesions. We have paid full attention to the above possible surprises and complications and have taken various preventive and countermeasures, and will do everything possible to avoid their occurrence during the operation. If any of these problems occur, we will take appropriate treatment in a timely manner to minimize the risk. We hope that you will fully understand, eliminate your worries, be confident, treat positively, support and cooperate with our medical work, so as to reduce complications and improve the efficacy of treatment. 4.Alternative options: Chinese and Western medicine medication, expectation observation, or laparoscopic surgery examination. 5.Post-operative matters should be noted: 1) pay attention to rest and nutrition; 2) keep the vulva clean, you can take a shower, but no tub bath for two weeks; 3) no sex in this cycle; 4) if you have abdominal pain, fever, more vaginal bleeding than usual menstrual flow and abnormal vaginal discharge, please consult a doctor in time.
