The conditions requiring surgery are as follows: 1. submucosal fibroids: submucosal fibroids cause excessive menstruation and sometimes lead to secondary anemia, which requires surgery; 2. subplasmalemma fibroids: some subplasmalemma fibroids are twisted and patients show severe pain in the lower abdomen, which requires emergency surgery; 3. oversized fibroids: they cause compression symptoms, because the front of the uterus is the bladder and the back is the intestinal canal. If the fibroids in the front wall of the uterus are too large, they can cause frequent urination, and if the fibroids in the back wall are too large, the patient can have the performance of falling, which also needs surgery. If the growth of fibroids is too fast and malignancy is suspected, surgery is also needed; 4. fibroids are found before and after menopause: or the growth of fibroids is accelerated after menopause, then it is feared that the fibroids will become malignant, that is, sarcoma-like changes of fibroids, at this time, surgery should be rushed to avoid degeneration.
