Uterine adhesions are the adhesion of the anterior and posterior walls of the uterine cavity together and are commonly seen after an abortion or an infection in the uterine cavity. In normal uterine cavity, adhesions do not occur if there are multiple abortions, intrauterine surgery, endometritis, or after endometrial electrosurgery, causing fibrinogen leakage from the uterine mesenchyme, causing adhesions between the anterior and posterior walls of the uterine cavity, and clinically, those with a history of such adhesions may also experience amenorrhea, or menorrhagia, abdominal pain, secondary infertility, miscarriage, and other symptoms. Usually, you can check through the hysteroscope, which is more intuitive and can understand the presence or absence of adhesions and the location, extent and degree of adhesions, or hysterosalpingography, but hysteroscopy is more commonly used. Uterine adhesions can be classified as total or partial adhesions and can usually be treated with medication or surgery, such as hysteroscopy. In conclusion, most of the uterine adhesions have a history of uterine manipulation, which refers to partial or total adhesions in the anterior and posterior walls of the uterine cavity, and can generally manifest as abdominal pain, menorrhagia, amenorrhea, infertility or miscarriage, which can be examined and treated by hysteroscopy.
