Attention should be paid to: 1 after prepuce operation. Before the wound heals, follow-up visits should be made regularly. 2. The postoperative wound should be kept clean and dry, and be careful not to wet the gauze when urinating. 3. The wound is sutured with absorbable suture, so there is no need to remove the suture. 4. If there is penile erection, please protect the wound with one hand and pinch the glans with the other hand to let the penis fade naturally to avoid the wound from cracking. 5. If the wound is swollen and bleeding, local cold compress and pressure can be applied to stop bleeding; If the bleeding is serious, you should go back to the hospital immediately. 6. It is forbidden to masturbate and have sex. 7, drink more water, eat more fruits and vegetables and legumes. Try not to eat cold, spicy and greasy food. 8, prepare more pairs of underwear for washing (or buy disposable pants), because the interstitial fluid will seep out and stain the underwear during the recovery period. It takes about 40 days after the operation to move normally.
