A urinary catheter is required for liver cyst surgery because of the relatively long duration of liver cyst surgery. If a urinary catheter is not left in place, there is a risk of bladder rupture once the patient is accompanied by a large amount of urine pooling in the bladder during the operation. Moreover, general anesthesia is required for liver cyst surgery, and no consciousness exists during the surgery. Inserting a catheter can help the urine to be discharged in order to prevent the urine from gathering too much in the bladder or leading to inflammation of the urinary tract. After the operation, you should pay attention to personal hygiene, eat a light diet, avoid cold, greasy, indigestible food, choose fluids, as well as soft, easy to chew food, eat more fresh fruits and vegetables. According to the individual’s condition, go to the hospital regularly for review, do some aerobic exercise, such as running, jogging, swimming, etc., avoid emotional excitement, keep a calm mind.
