Circumcision is also a traumatic treatment method, which also requires anesthesia and cutting, hemostasis, suturing, etc. There are certain risks, including: 1, in the case of children, general anesthesia is required, general anesthesia can be the risk of respiratory and cardiac arrest, the chance of occurrence is very low, but theoretically there is still a risk of anesthesia accident. 2, local anesthesia patients can have a transient anesthetic allergy, chest tightness, heartburn, shortness of breath or even shock, which is rare clinically. 3. The risk of infection exists in all surgeries, as bacteria can contaminate the incision during the tissue cutting and suturing process, or urine can contaminate the incision during the later healing process and cause infection, which can lead to wound bleeding, wound dehiscence or septicemia, and patients can develop fever or local ulceration. 4. Pain, difficulty in urination, etc. Due to post-operative pain and infection, it can lead to urinary system infection, frequent urination, urgent urination and painful urination. When acute infection occurs, there is a risk of acute difficulty in urination due to urethral congestion and edema. 5. Scarring can occur after surgery and cause narrowing of the foreskin opening, causing scarring changes in patients. This condition requires a second surgery for treatment. 6. Risk of secondary bleeding from surgery, the risk of the wound breaking open and breaking apart due to frequent erection of the patient’s penis after surgery, leading to bleeding from ruptured blood vessels and the need for another surgery.
