Excuse me, I can't see the mediastinal uterus clearly by B-ultrasound. What should I check to see clearly?

Overview of uterine mediastinum The uterine mediastinum is caused by congenital development and obstruction during the fusion of double accessory kidneys. The incidence of uterine mediastinum and bicornuate uterus was 5%. Uterine mediastinum changes the symmetrical shape of uterine cavity and may interfere with normal reproductive function. It is easy to cause primary infertility or intractable infertility. Clinical manifestations of uterine mediastinum Most patients with uterine mediastinum are asymptomatic, and some patients may be accompanied by increased menstrual flow. However, most of the uterus mediastinum has a history of repeated abortion, infertility, premature delivery and abnormal fetal position, and some of them were found during cesarean section or induced abortion curettage. Secondly, some patients found vaginal mediastinum during pelvic examination, and doctors further examined and found mediastinal uterus. Even if the uterus is pregnant, the incidence of intrauterine growth retardation and intrauterine death is relatively high, because this diaphragm has fewer blood vessels and more fibrous tissue than normal uterus, which hinders normal implantation; In addition, the endometrium covering the septum has poor response to hormone stimulation, and the septum can hinder the normal growth of placenta and lead to early fetal death. If you can continue to be pregnant, it will also develop into intrauterine growth retardation. Diagnosis of uterine mediastinum 1 and dynamic digital hysterosalpingography are one of the important examination methods of uterine mediastinum; 2. Four-dimensional transvaginal color Doppler ultrasound is more accurate in the diagnosis before menstruation; 3. Hysteroscopy: Hysteroscopy can directly and accurately judge the type of uterine mediastinum, and it is the "gold standard" for diagnosing uterine mediastinum, distinguishing complete and incomplete uterine mediastinum, and simultaneously diagnosing uterine cavity and its lesions. Before hysterectomy, hysteroscopy should be performed routinely. The relative risk of miscarriage and premature delivery caused by uterine mediastinum ranges from 5% to 95%, so once found, it should be treated in advance. Before the appearance of hysteroscopy, the surgical method to treat uterine mediastinum was to remove mediastinum through vagina or abdomen. The former is difficult and blind, which leads to incomplete mediastinal resection and poor effect. Abdominal surgery is to cut the mediastinum horizontally at the bottom of the uterus, or cut the uterine body in the middle, trim the mediastinum and rebuild the uterine muscle wall. Any of the above operations will leave scars on the uterus and abdominal wall, with great trauma, long recovery time and even uterine adhesion, which will have a certain impact on future pregnancy. It will take several years to get pregnant and more cesarean sections are needed. Hysteroscopic hysterectomy is a minimally invasive surgical treatment. Hysteroscopic hysterectomy is to remove the residual vascular embryo tissue. There was no obvious bleeding during the operation, little trauma, quick recovery, postoperative ring release and artificial circulation to prevent adhesion. & lta href =/& gt； Antai therapy-Hysteroscopy combined with cold knife hysteromediastinal separation
