Patients with bladder stones, after surgery, are generally not allowed to eat on the day of the surgery due to anesthesia. Doctors will maintain the nutritional balance in the patient's body through intravenous fluid supplementation. On the second day after surgery, patients can consume liquid and easy-to-digest foods such as porridge and vegetables, and should avoid spicy and irritating foods. After three days, when the patient's bowel movements are regular, they can then resume a normal diet including rice, vegetables, fish, and meat.
