Although laser surgery for prostate enlargement is a minimally invasive procedure, it requires anesthesia, postoperative care, and patients are usually older and less able to take care of themselves and need nursing care. Prostatic hyperplasia is most common in elderly men, who are older and may not be able to move easily, and need a chaperone to assist with their daily lives. In addition, continuous bladder irrigation is required after surgery, and the volume of bladder irrigation fluid is relatively large, so a chaperone is needed to assist in changing it, and routine monitoring of the patient’s urine output and the amount of flushing may also be required after the surgery, which requires a chaperone to complete. Therefore, after prostate laser surgery, on the one hand, it is the cooperation of the patient himself, and the selection of an appropriate chaperone is also very important.
