In addition to surgery, I spend most of my time on …… consulting with adenomyosis patients from all over the country. When you get in touch with more patients, you will find that although most of them have severe dysmenorrhea, you will find that they have the same dysmenorrhea, but their conditions are different, not only the degree of dysmenorrhea, but also the location of the dysmenorrhea. Why do menstrual cramps occur in different places? The uterus is in the middle of a woman’s lower abdomen, most menstrual pain patients are in the middle, that is, the normal position of the uterus pain, but some patients will appear in the side, left or right, there are several reasons for this situation: 1, lesion growth bias to one side For example, if the lesion always grows in the left side of the uterus, then the left side is more painful, grow in the right side, the right side is painful. If the patient with this pain is more serious, not only will she have pain on one side of her stomach, but she will also have back pain, leg pain and back pain on this side. This is a relatively rare situation where not only is there a lesion in the uterus, but the lesion is also thought to be outside the uterus, such as a lesion ectopic to the ureter, where there are ureters on the left and right sides of the uterus, and if there is endometriosis around the ureter, then this time there will also be pain on one side. What should I do during surgery for adenomyosis patients with pain on one side? For patients who have pain on one side, the first thing we do is to see if there are more lesions on the side where the patient has pain. If there are more lesions, it means that the pain is caused by the lesions on one side, if there are not more lesions, we have to see if there are lesions around her ureter.
