There are many diseases that require gynecological surgery, as follows: 1. benign lesions of the uterus and ovaries: for example, uterine fibroids and benign ovarian tumors. 3. pregnancy-related diseases: for example, abortion, curettage if there is residual uterine cavity after abortion, abortion if there is staph, and emergency surgery for ruptured ectopic pregnancy. If women with ectopic pregnancy do not have high blood HCG and the mass in the adnexal area is not large, they may need conservative treatment, and in the process there is always the possibility of ectopic pregnancy rupture and bleeding, so they should also be prepared to do surgery. 4. ovarian tumor torsion: patients will have severe abdominal pain and need emergency surgery. 5. endometrial polyps, uterine adhesions, uterine diaphragm: patients need to do hysteroscopy before deciding whether to do surgery. Gynecological diseases do not necessitate surgery as soon as they are detected, and the gynecologist needs to make a decision whether to do surgery. Some diseases can be observed for a period of time, and if the lesion does not disappear or if the symptoms worsen, surgery is required.
