The preferred treatment for renal pelvis cancer needs to be judged comprehensively by combining many factors such as pathological type and progress of the disease, and the commonly used treatment plans in clinic include surgery, radiotherapy, chemotherapy and so on. 1. Surgery: for early-stage renal pelvis cancer without metastasis, radical resection should be carried out as early as possible, and it is necessary to do the resection of the whole length of the kidney, ureter and the bladder wall at the opening of the ureter, and it is possible to choose open surgery or laparoscopic surgery. 2. Radiotherapy: for high-grade invasive tumors, postoperative radiotherapy can be combined with local radiotherapy, which can reduce the recurrence rate of local tumors and may improve the survival rate. 3. Chemotherapy: Intratumoral chemotherapy can effectively reduce the recurrence rate of the tumor, which is mainly applicable to renal dysfunction and bilateral multiple superficial tumors, carcinoma in situ and adjuvant treatment after local excision. Other treatment options include arterial embolization, conservative treatment, etc. If renal pelvis cancer is found, it is necessary to consult doctor in time and standardize treatment to avoid delay.
