Pediatric cryptorchid surgery has certain risks, the risks include the risk of anesthesia itself and the risk of surgery itself, the risk incidence is low but not without any risk, similar to the size of appendectomy done by general surgery, the risk is equal to the risk of appendectomy. Specific risks include: 1. the risk of anesthesia, the existence of postoperative awakening difficulties or laryngeal edema, airway infection, etc. 2. intraoperative bleeding and postoperative pain. 3. the risk of finding the cryptorchid during surgery and the risk of failure due to the inability to find the cryptorchid. 4. the risk of staged surgery to lower the testicle into the scrotum if the testicle is in a high position and cannot be lowered into the scrotum at once. 5. the risk of postoperative testicular retraction or 6. Risk of postoperative testicular ischemia, necrosis or wound infection affecting testicular blood supply.
