What is the cause of foreign matter in the uterus?

The uterus is a central point like a house in the female body. If this house is destroyed, problems will arise in all aspects of the body. Many adnexal inflammations and ovarian diseases are caused by problems with the uterus, which will gradually lead to these complications. Therefore, we must pay more attention to the health of the uterus. In addition, many people say that there will be foreign objects in the uterus, and this also requires checking specific factors.

Generally, you should pay attention to the following before a physical examination:

1. Gynecological examinations should be performed away from menstruation. The best time to do so is 3-10 days after menstruation ends.

2. Within 24 hours before the examination, you can wash the vulva, but avoid taking a bath or washing the vagina to prevent the abnormal cells in the vagina from being washed away, resulting in insufficient smear specimens and affecting the diagnosis;

3. Before the examination, avoid using vaginal suppositories and avoid having sexual intercourse;

4. Wear loose clothing to facilitate inspection;

Location

The uterus is located in the middle of the pelvis, between the bladder and rectum. Its position may vary depending on the fullness of the bladder and rectum or body position. When standing upright, the uterine body is almost parallel to the horizontal plane, the uterine fundus lies above the posterior and superior part of the bladder, and the cervix remains above the plane of the ischial spines. The normal uterus of an adult is in a slightly anteverted and anteflexed posture. Anteversion means that the uterine axis and the vaginal axis are open forward at an angle, and anteflexion is the curvature between the uterine body and the cervix.

The normal position of the uterus is mainly maintained by structures such as the uterine ligaments, pelvic diaphragm, urogenital diaphragm and perineal central tendon. When these structures are damaged or loose, uterine prolapse may occur. The uterus can be divided into four parts: fundus, body, isthmus, and cervix. The upper end is blunt and rounded, and the part located above the cervical opening of the fallopian tubes on both sides is the fundus; the narrow and cylindrical part at the lower end is the cervix, which is a frequent site of inflammation and cancer. The cervix is ​​further divided into the upper vaginal part and the vaginal part. The part between the bottom and the neck is the body; the narrow part between the lower part of the body and the neck is the isthmus. The uterine isthmus gradually expands with the pregnancy period, and the lower uterine segment is obviously formed at the time of delivery. Obstetricians often perform cesarean section to deliver the fetus here.

The place where the upper part of the two sides of the uterus meet the fallopian tubes is called the uterine horns. The front of the uterus is adjacent to the top of the bladder through the vesico-uterine pouch, the front of the upper part of the cervix and vagina is adjacent to the bottom of the bladder through the vesico-vaginal septum, and the cervix and vagina are adjacent to the urethra through the urethrovaginal septum; the back of the uterus is adjacent to the rectum through the rectouterine pouch and the rectovaginal septum.

The uterus is located in the center of the pelvis, between the bladder and rectum. The uterus of a normal non-pregnant adult woman is in an anteverted and anteflexed position, and the main fixation devices for the uterus are the support of the pelvic diaphragm and vagina and the traction and fixation of the ligaments. The four pairs of ligaments are the broad ligament of the uterus, the round ligament of the uterus, the cardinal ligament of the uterus, and the sacro-uterine ligament.

The uterus is inverted pear-shaped, flat in front and slightly protruding in the back, with wide walls and a small cavity. The upper end is wide and free, facing forward and upward; the lower end is narrow and cylindrical, inserted into the upper part of the vagina. The average length, width and thickness of an adult female's uterus are 7×5×3 cm, and the uterine cavity capacity is about 5 ml.
