If the circumcision fails, it is recommended to analyze the reasons for the failure and decide how to deal with it. 1. If the child’s cooperation is poor due to the wrong choice of anesthesia, resulting in the failure of the operation, it is recommended to be hospitalized for general anesthesia, when the patient achieves good cooperation and saves the operation from failure. If the child is too young and local anesthesia is chosen, and the child is extremely uncooperative during the surgery, the doctor cannot perform the surgery, then immediately hospitalized and perform general anesthesia for surgical treatment. 2. If infection occurs after the surgery, resulting in the wound splitting or not healing, it is recommended to perform debridement and wait for the wound infection to be controlled, then perform secondary suturing and repair to save the failed surgery. 3. Or if the foreskin is excised too little during the surgery, and still shows prepuce after the surgery, it is recommended to be hospitalized again for repair of the surgery under local or general anesthesia, or urethral stricture incision to save the failure of the surgery.
