According to statistics, about 80% of patients can conceive through non-invasive or minimally invasive treatment, but about 20% of patients are difficult to conceive through traditional treatment, i.e. patients with distal tubal obstruction with hydrocele. Patients with hydrocele will cause the umbilical end of the fallopian tube to become stiff and lose its softness, and the umbilical end will not be able to pick up eggs. Therefore, these patients are recommended to conceive directly through artificial insemination and IVF. Before IVF, patients with distal tubal obstruction with hydrocele should undergo tubal embolization because hydrocele can cause backflow of water into the uterine cavity from time to time and cause the fertilized eggs transplanted in the uterine cavity to fail to settle in the endometrium, resulting in failure of IVF conception. There are two types of tubal embolization treatments: surgical resection (which is characterized by great damage and is difficult for patients to accept). Second: tubal interventional non-invasive embolization (its characteristics, non-invasive, painless for patients, its disadvantages are relatively high requirements for doctors and treatment facilities, so it is difficult for general medical institutions to implement,)
