Painless abortion can be categorized into general painless abortion, ultrasound-monitored painless abortion, ultrasound-monitored painless abortion, superconducting visualized painless abortion, or hysteroscopic-monitored painless abortion. Among these painless abortion surgeries, hysteroscopic-monitored painless abortion has the highest rate of success, and the least amount of damage to the patient’s uterine lining. Because the hysteroscopic operating room is able to place a probe directly into the woman’s uterine cavity, it can observe the size and location of the residue. The residue can be cut or scraped off directly without damaging other parts of the uterine lining, so the damage to the patient’s uterine lining is minimized, and postoperative recovery is fastest. However, the hysteroscopic painless abortion procedure is the most expensive, costing about$7,000. Because this procedure requires hospitalization and is performed in an operating room under the supervision of an anesthesia room, the cost is relatively high.
