I did it in the Third Hospital of Beijing Medical University on March/0/9. It is recommended to bring the laboratory test sheet of routine examination of liver function and blood in the original hospital when making an appointment, otherwise you may be required to have a blood test. Surgery is usually arranged in the afternoon, in front of the gynecological B-ultrasound room. You can eat in the morning and empty your bladder before operation. B-ultrasound-guided surgery will not harm the fetus, which can be assured. It is best to observe for half an hour before leaving after operation (because there is no special observation room in the Third Hospital of Beijing Medical University, it is recommended to sit on the bench at the entrance of the operating room for a while before leaving, and you can find a doctor to deal with anything in time). No bathing for 24 hours after operation, and no water in the eye of the needle. You can drink plenty of water properly. Generally, the results will be known within 3 weeks after operation, so you can call this hospital for telephone investigation (Third Hospital Telephone 1 14). Wish LZ all the best!
