Surgical failure: some patients may have surgical failure and poor postoperative effect of hidden penis surgery, resulting in the penis remaining in the hidden state. 3. Localized infection, ischemia and necrosis of the foreskin: localized infection, ischemia or necrosis of the foreskin may occur after the operation of hidden penis, such as ischemia of the foreskin flap, localized black ischemia and necrosis or ulceration and other manifestations. 4.
