Uterine perforation can be detected at the time of surgery, due to the fact that most uterine perforations are caused during surgical operations. For example, during IUD placement, or during abortion, uterine perforation can easily occur due to the soft texture of the uterus or the abnormal position of the patient’s uterus, such as extreme anterior or retroflexion. During the procedure, when the doctor finds that there is no resistance after the instrument goes in, this situation should be considered as uterine perforation. If the uterine perforation occurs, the operation should be stopped immediately. If the perforation is a small probe perforation, the uterus can be strengthened by contraction with hysterectin to allow the small rupture to heal, and if it is a large instrument perforation, the patient should be hospitalized for observation, and sometimes surgery is required.
