Circumcision is a surgical maneuver usually used in urology for the treatment of phimosis or circumcision. Circumcision is currently categorized into traditional open surgery and surgery using a circumcision anastomosis. 1. Traditional circumcision: Traditional circumcision is a circular excision of the excess foreskin at a distance of 0.5~1cm from the coronal sulcus, with hemostasis and interrupted sutures. 2. Anastomosis circumcision: using anastomosis surgery, cutting, hemostasis and anastomosis are completed in one go. Compared with the traditional surgical methods, the time is short, the bleeding is less, and the incision is neat. Overall, people who are circumcised or circumcised can go to the hospital for examination, and then the professional doctor will judge whether they need to do circumcision treatment.
