Hydrosalpinx, also known as tubal effusion, refers to a large amount of congestion and edema in the fallopian tube, and fallopian tube contains a large amount of liquid. Hydrosalpinx is a common gynecological inflammation that causes menstrual disorders, abdominal pain, and long-term infertility. How is the hydrosalpinx formed? First, caused by chronic fallopian tube of inflammation. Chronic fallopian tube inflammation will produce some inflammatory secretions. If the chronic salpingitis is not cured for a long time, the umbrella end of the fallopian tube can be blocked by inflammation, and the leakage and exudate gradually accumulate in the tubal lumen. Second, evolved from the fallopian tube empyema. The pus cells and necrotic tissues in the lumen are decomposed and cleared by phagocytic cells, and the pus gradually turned into a clear water. There are some people of hydrosalpinx not caused by inflammation of the fallopian tube, it is caused by tubal sterilization. Because the fallopian tubes are interoperable, the hydrosalpinx is mostly bilateral, and long-term hydrosalpinx can also cause tubal adhesion or tubal adhesion to the ovary. Sometimes the oviduct of the stagnant water adheres to the ovary and interacts with the follicular cyst in the ovary to form a fallopian tube ovarian cyst. Hydrosalpinx, for young women, it is not recommended to use the method of resection of the fallopian tube. Fuyan pill is a conservative traditional herbal medicine. It has good effect on eliminating inflammation and curing fallopian tube of inflammation.
