Surgery to repair leakage after hypospadias surgery is usually performed to restore the continuity and integrity of the urethra, and should be performed under the supervision of a medical professional. The surgery is usually performed to restore the continuity and integrity of the urethra due to the appearance of one or more fistulas at the urethral anastomosis after the first stage of surgical treatment, as a result of which urine leaks out from places other than the normal urethral orifice, which makes it difficult for the skin around the fistulas to grow back and causes a certain degree of disturbance to the patient’s life, and the surgery is usually performed to restore the continuity and integrity of the urethra. The procedure involves not only removing the fistula, but also completely removing the surrounding scar tissue and fibrous striated tissue, and then repairing the fistula. The procedure is performed by a specialized physician and should be treated aggressively in the event of discomfort.
