1.How long is the postoperative bandage best? About 7 to 10 days. 2.How to keep the wound gauze clean and dry after surgery? Tilt your body forward when urinating (or bend forward) so that the urethral opening is downward, and wipe the urine from the urethral opening with a tissue at the end of urination to avoid wetting the dressing with urine. Or prepare an empty drink bottle and put the urethral opening into the bottle every time you urinate, so that even if the urine is scattered, it is scattered in the bottle and will not wet the gauze. If the gauze is wet a little, you can use a hair dryer to blow dry, if it is all wet, come to the hospital immediately to change the medicine. 3.Why should I wear loose pants after surgery? Wear loose pants to reduce the friction of the penis. In addition, loose breathability is good for wound drying and promoting wound healing. 4.What is the contraindication of diet after surgery? Avoid alcohol, spicy and other stimulating foods for one week after surgery, and eat more fish, meat, eggs, fruits and other foods, which are good for wound healing. 5.Can I participate in sports activities after surgery? During the healing period, try to reduce activities and prohibit strenuous activities. 6.When can I have intercourse after surgery? One week after the staples fall off completely on their own, use condoms for early intercourse to prevent wound dehiscence.
