After cryptorchidism surgery, attention should be paid to: 1. Avoid seeing water in the early stage, such as bathing or showering, etc. It is usually recommended to take a shower after two weeks, but not a bath, and a bath after one month. 2. Avoid strenuous activities, i.e. normal walking and living without any problems after surgery, but avoid strenuous running, ball games or heavy physical labor, etc., so as not to cause testicular retraction or hernia recurrence. 3. 4. Pay attention to the protection of the wound and avoid premature contact with pollutants, such as urine or other pollutants, so as not to cause wound infection.
