Regular follow-up of human chorionic gonadotropin is very important after the clearance of staphyloma. Patients with staphyloma must be followed up strictly and regularly after clearance to detect trophoblastic tumors as early as possible and to deal with them in a timely manner. The detailed testing method is once a week after clearance until three consecutive negative tests, then once a month for six months, and then once every two months for six months, for a total of one year since the first negative test. The follow-up of staphylococcal fetus should be done not only by regular rechecking of human chorionic gonadotropin, but also by taking medical history including menstrual status, presence of vaginal bleeding, coughing and coughing up blood, and if necessary, by optional ultrasound, X-ray or CT. patients with staphylococcal fetus should have reliable contraception during the follow-up period, which is recommended for six months.
