A woman’s fallopian tubes are the place where sperm and egg meet for fertilization, so clear and well-functioning tubes are one of the essential conditions for natural conception. So how to check whether the fallopian tube is smooth? 1, tubal fluid test: easy to operate, inexpensive, because of its diagnostic criteria mainly rely on the doctor’s subjective feeling, so only about 50-60% accuracy, only as a young, infertile patients with a short period of time of the initial screening method, but also for mild adhesion to play a role in unblocking. For more than one year of infertility, the method of tubal lining is not favored to check the fallopian tubes. In addition ultrasonic tubal fluids, although the effect is better than ordinary uterine tubal fluids, but still can not specify the location of tubal obstruction, there are certain limitations. 2, uterine tubal imaging: easy to operate, rapid, high diagnostic accuracy, low side effects, is an important method of detecting the smoothness of the fallopian tube, widely used in clinical practice. The X-ray film taken through the imaging can leave the picture data. Our hospital uses digital subtraction angiography X-ray machine (DSA) to do hysterosalpingography, its advantages: the patient’s exposure to X-rays is greatly reduced, the accuracy is high, with the effect of playback and play a certain role in unblocking the fallopian tube. 3.Hysteroscopic tubal fluids: it has the advantages of direct vision, minimally invasive, safe and so on. Under the direct vision to exclude the cervical tube, cervical endocervix, endometrium and fallopian tube openings have lesions, and under the direct vision of the bilateral fallopian tube tube insertion through the Meilan liquid, can check the fallopian tube and can dredge the fallopian tube. If endometrial polyps, adhesions and other abnormalities in the uterine cavity are found during hysteroscopy, they can be treated accordingly. Since we started this program, the pregnancy rate has increased significantly. 4.Laparoscopic tubal dyeing and fluids: it 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 one of the best means of routine examination for infertile women. And can find early endometriosis, some unexplained infertility patients to find the cause. However, laparoscopy is an invasive examination, often not easy to be accepted by patients. Therefore, patients need to go to a regular hospital and choose the appropriate method to check the fallopian tubes according to their condition.
