The maximum life expectancy for renal pelvis cancer is not a definitive figure; if the renal pelvis cancer is free of metastases after radical resection, the usual 5-year life expectancy is about 60-90%. If the tumor is well differentiated and the pathological type is less malignant, the overall survival can exceed 10 years. Renal pelvic cancer is a more malignant type in the urinary system, and its postoperative survival rate is related to the patient’s TNM stage and the degree of tumor cell differentiation. For early low-grade renal pelvis cancer with diameter less than 2cm, if radical resection of renal pelvis cancer can be performed at an early stage and there is no metastasis to lymph nodes and distant organs, the survival period may be 5-10 years. However, for patients with high-grade renal pelvis cancer, or with size larger than 2cm, and with advanced symptoms such as regional lymph node metastasis or even distant lung metastasis or bone metastasis, the prognosis is extremely poor, and the tumor usually recurs and progresses in about 12 months. The recurrence rate of renal pelvis cancer is relatively high, which can easily lead to implantation metastasis of the bladder. Risk factors of patients should be found out according to their conditions and individual differences, and home care should also be provided to patients in terms of psychology, diet, activity and rest, and plumbing care.
