The posterior wall of the uterus is a part of the uterus. The female uterus is an inverted triangle divided into the base of the uterus, the body of the uterus, and the cervix. The anterior wall of the uterus is the side of the uterus that can be seen through the abdomen of a woman. The anterior wall of the uterus is adjacent to the bladder and can compress the bladder when there is a tumor lesion in the anterior wall of the uterus, resulting in clinical symptoms such as frequent urination, urgent urination and incomplete urination. The posterior wall of the uterus is the side of the uterus that can be seen from the back of the body and is adjacent to the rectum of women. When tumor lesions appear in the posterior wall of the uterus, it is easy to compress the rectum or adhere to the rectum, resulting in constipation, abdominal pain, blood in the stool and other abnormal conditions.
