You can eat protein-rich foods after kidney stone surgery, such as eggs, duck eggs, lean meat, and milk, and you need to eat fruits and vegetables, such as oranges, apples, and cabbage. Kidney stone surgery is an invasive operation and you need to wait for the wound to heal after the surgery. Nutrients are needed during the healing process, and foods containing more protein are necessary to promote wound healing, such as the above-mentioned eggs, milk and lean meat. Therefore, it is recommended that patients who have had kidney stone surgery should eat more of these foods in moderation to get enough protein to promote wound healing. In addition, after the surgery, the patient is not very active and mostly rests in bed, so the patient is easily constipated, which is not good for the wound healing. Therefore, after kidney stone surgery, it is recommended to eat more vegetables and fruits to help relieve constipation and prevent high abdominal pressure, which can make wound healing difficult.
