After uterine artery embolization for uterine fibroids and adenomyosis, many patients are more worried when they experience pain in the lower abdomen and anal swelling, even after being discharged from the hospital. In fact, this is mainly due to not being able to undergo this procedure. Interventional treatment of the uterus, which seems to have no wounds and a very small trauma on the surface, actually undergoes a drastic change in the uterus. When the interventional treatment is performed, as the uterus first becomes ischemic, then after 2-3 days the blood flow to the uterus is restored, then it enters a process of edema for more than 20 days and finally returns to normal. Basically, this is a necessary process after uterine intervention. Therefore, the uterus will be larger than usual for 20 days after the intervention, causing the patient to feel pain in the lower abdomen or anal swelling, but as the uterus recovers, such feelings will get better and lessen day by day, and finally return to normal. Therefore, there is no need to worry about this postoperative condition, which is a normal reaction.
