Tubal pathology is an important cause of infertility. About 40% of the causes of female infertility are related to structural and functional abnormalities of the fallopian tubes. Therefore, tubal examination is an important element in the diagnosis of infertility. Tubal fluids, ultrasonography, X-ray hysterosalpingography and laparoscopy are commonly used to check the patency of the fallopian tubes. [Tubal Fluid Test] This is commonly referred to as “tubal fluid test”. Although the operation is simple and cheap, the accuracy is greatly reduced because the diagnostic criteria mainly rely on subjective sensation to determine whether the fallopian tube is open or not according to the fluid reflux and resistance. For patients who have been infertile for many years and have a history of surgery, especially those with endometriosis, I am not in favor of using the method of tubal fluid passage to diagnose the patency of the fallopian tubes. Unless there is no better test available. It is especially not recommended that repeated tubal fluids be applied as a therapeutic tool when the tubes are known to be patulous. Uterine Tubal Ultrasonography] This test has been gradually used for clinical evaluation of tubal patency due to the availability of ultrasonic contrast agents and the development of acoustic imaging techniques. However, since this test is not as widely used as X-ray tubalography, it is difficult for doctors to accurately interpret the images provided by medical institutions that do not have this technology. Hysterosalpingography is a test in which a contrast medium is injected into the uterine cavity through the cervical canal and X-rays are taken to examine the uterus and fallopian tubes. It is an important method to test the function of fallopian tubes and is widely used in clinic due to its easy and rapid operation, high diagnostic accuracy and low side effects. Tubal imaging in the examination can through the display screen dynamic observation of the shape of the uterus, can be found in the fallopian tube proximal or distal blockage, to understand the tubal alignment, suggesting that the umbrella end of the adhesion or adhesion around the fallopian tube, but also through the imaging X-ray film can leave a permanent picture of the information, regardless of which hospital inspection and treatment, can be used as a basis for diagnosis. It is recommended that patients and friends of their own imaging films should be properly preserved. Or take a picture of yourself and save it on your cell phone. Laparoscopic Tubal Dyeing and Fluidization, or known as Laparoscopic Methylene Blue Fluidization, can dynamically observe the degree of tubal patency under direct vision, and at the same time, it can also comprehensively and accurately assess the nature and degree of lesions in the pelvic organs, which is widely recognized as the “gold standard” for evaluating the patency of the fallopian tubes. Laparoscopy can also detect early endometriosis, pelvic tuberculosis, etc., and find the cause for some unexplained infertility. For patients with tubal adhesion and fluid accumulation, corresponding surgical treatment can be performed under direct vision. Therefore, laparoscopy has both diagnostic and therapeutic effects. However, laparoscopy is an invasive procedure and it is not recommended to take the risk of surgery just to find out if the tubes are open. It should be chosen when indicated. Question and Answer Time [I want to have my tubes checked, what should I do] Go to the hospital, it’s a must. Tell the doctor your medical history and make your request. The doctor will then analyze your condition comprehensively and give you advice and guidance. The doctor will then analyze your condition and give you advice and guidance, and make arrangements. The time of the examination] No matter what kind of examination, it is usually scheduled for 3-7 days after menstruation, and 3-5 days before the operation, coitus is prohibited. Which method should I choose? Generally, you don’t have to choose, but it depends on which method is currently used in your hospital. I generally recommend choosing X-ray hysterosalpingography. [Is it painful and can I be anesthetized?] Hysterosalpingography is a commonly used test for infertility diagnosis. There may be some discomfort during the test, but it is generally tolerable. It is best to be accompanied during the test. The availability of anesthesia should be based on the hospital’s arrangement. As far as I know, most of the hospitals do not have anesthesia for imaging. What kind of examination should be done before the imaging】 Each hospital has different requirements. It is recommended to follow the requirements of your hospital. Generally, it is necessary to do a gynecological double examination, vaginal secretion examination, and some related infection indicators. Dr. Kennedy, I heard that imaging is not good for the body, can I not do it? There is no such thing as a person who fights to have an imaging test for nothing. Doctors recommend it because it is needed. When you put the need and the possible risks on the scale, the need is the heavier end. This test is important for infertility patients to choose the direction of treatment. If your doctor recommends it, then I suggest you follow the doctor’s instructions with informed consent.
