The accumulation of pus in the uterine cavity is mainly caused by inflammatory exudate, which means that it is related to the infection of inflammation and has nothing to do with the physical treatment of celiac disease. Whether acute or chronic endometritis is accompanied by obstruction of the cervical canal so that the inflammatory secretions in the uterine cavity cannot flow out or are poorly drained, pus can form in the uterine cavity. The main causes of pus accumulation in the uterus are: uterine bleeding; endometritis; cervical canal adhesions and blockage; genital malformations. In case of pus accumulation in the uterus, the patient may experience pain in the lower abdomen, increased leucorrhea and bloody discharge. In these cases, patients should go to a regular hospital and undergo hysteroscopy and hysteroscopy to determine the cause of the abscess and then treat the abscess accordingly. Abortion can also cause pus in the uterus, which can be examined by ultrasound. The most common cause is inflammation of the fallopian tubes or pelvic peritoneum. When the fallopian tubes are inflamed due to gonococcal infection, tuberculosis infection, chlamydia infection, mycoplasma infection or other bacterial infections, it can destroy the epithelial tissue of the tubal lining and occlude the fallopian tubes. The inflammation can cause the mucosa of the fallopian tubes to be destroyed and scarred, causing luminal narrowing or obstruction. Prognosis: general inflammatory cystic pus can be cured after active treatment; cancerous cystic pus has poor prognosis. How to do prevention in life? Infectious diseases should be diagnosed early and treated actively; for patients with malignant diseases, “tertiary” prevention work should be done for tumor patients. After women of childbearing age enter old age, they are prone to gynecological diseases because of the atrophy of reproductive organs, the cessation of ovarian secretion of estradiol, and the gradual decline of immune function. In view of the characteristics of the disease, the following preventive measures are proposed: 1. Strengthen the health education of postmenopausal women, bathe regularly, change underwear regularly, and keep the vulva clean and dry. 2, appropriate participation in physical exercise. 3, maintain a relaxed mood, enhance the immune system. 4.Take out the intrauterine device during the perimenopausal period, and if there is any discomfort, seek medical attention in time. 5.Annual routine gynecological examination, pay attention to control their own diseases such as diabetes.
