（According to statistics, 80% of bladder cancers are superficial, that is, they only grow on the surface of the bladder wall and do not take root in the muscular layer of the bladder, so most patients can be treated with transurethral resection of bladder tumors (TURBT). During the procedure, the surgeon sends an electric knife through the urethra into the bladder to cut out the tumor and flush it out directly. Because the urethra is a naturally occurring cavity in the body, the procedure does not leave any damage on the body surface. The procedure is not expensive, around $6,000 to $7,000, and the total cost of various expenses from hospitalization is about $10,000. Once a patient with bladder cancer is diagnosed as superficial, they can make an appointment for electrodesiccation, ideally in two to three days, for the surgery and cystoscopy, without having to go long between them. Patients who are taking warfarin or aspirin need to stop taking them for a week before surgery; a day or two before surgery, patients also have an anesthetic evaluation (cardiopulmonary function, electrocardiogram, cerebrovascular examination), and a urine bacterial culture test to ensure sterility and avoid urinary tract infection. The urinary catheter can usually be removed 5 days after surgery, and if there is nothing wrong, the patient can be discharged in another 1-2 days; the resected tumor will be sent for pathological examination during the surgery, which takes a week to confirm the diagnosis, so the pathological report will be available at the time of discharge; since all the resected tumor is sent for examination, the accuracy is greater than cystoscopic biopsy. If the postoperative pathology reveals a highly malignant tumor, further CT and MRI examinations are needed to see if muscle infiltration has occurred, which does not exclude the possibility of having a total cystectomy. Because of the recovery time required for electrosurgery wound and the inevitable bruising and contusion to the urethra during the surgery, urinary urgency and pain is a common discomfort reaction, although it will not last for a long time. It is added that if the patient has a narrow urethra due to urethral deformity or prostatic hyperplasia, the electric knife is not easy to insert, then the narrow part needs to be dilated during the surgery, and the damage will definitely be greater; if the narrowing is very serious, an incision in the stomach is needed to remove the tumor.
