Bladder cancer is a common urological tumor. The scope and method of surgery should be based on the comprehensive analysis of tumor stage, malignant degree and tumor size, location, whether it involves neighboring organs, etc. For the general knowledge of surgical treatment of bladder cancer, patients should also be informed. 1. Early stage of bladder cancer without metastasis is generally not life-threatening. Even if it recurs, if effective treatment measures can be taken in time, it is still possible to be cured. 2.Bladder cancer treatment mostly adopts comprehensive treatment mainly based on surgery, if there is no indication for surgery, radiotherapy and chemotherapy can be adopted. 3.The treatment method of bladder cancer surgery is chosen according to the different size of tumor. If the tumor is very small, only in the mucous membrane layer and has not metastasized to the depth of bladder or surrounding, the tumor cells can be cut off directly through urethra; if it has infiltrated to the depth of bladder muscle, part of the bladder or the whole bladder can be cut off. 4. When the bladder is completely removed, it is necessary to make another “bladder”, usually a section of ileum is cut from the patient’s body as a bladder, and the ureter is connected to it, and then an opening is made in the abdomen for urination, and the patient who has made a new “bladder” should actively carry out the recovery exercise after the operation in order to The patient with a new “bladder” should be actively engaged in postoperative recovery exercises to restore urinary function. Perfusion chemotherapy belongs to a kind of localized chemotherapy method, and patients who adopt this method have no influence on the quality of life, and have fewer side effects like hair loss. 6.After being discharged from hospital, patients should follow up regularly and pay attention to review, so that once recurrence occurs, it can be detected as early as possible, and cystoscopy is usually performed once every three months.
