The rupture of the white membrane is theoretically recommended to be completed within 7 days at the latest. The rupture of the white membrane generally refers to a fracture of the white membrane that is contained in the corpus cavernosum of the penis. It occurs mainly during sexual intercourse when the penis is fully erect and the external force causes damage to the rupture of the white membrane, spilling the blood inside, bending the penis and thus affecting erectile function. The significance of surgery is to remove the oozing hematoma, and suture the ruptured white membrane, reconstruct the penile structure, and achieve the purpose of protecting the function of the white membrane and sexual function. Therefore, in practice, it is recommended that the surgery be completed moderately early for patients who have the conditions to control the risk of infection and bleeding and to protect the patient’s future sexual function. If the surgery is done too late, the excessive exuding hematoma causes local irritation, which will make the surgery more difficult.
