Renal tumors are among the more common tumors of the urinary tract, most of which are malignant. Common clinical tumors include renal cell carcinoma, nephroblastoma, and tumors that occur in the renal pelvis and calyces. Kidney cancer is one of the cancers with better prognosis and its surgical treatment is very effective. If benign tumors are completely removed by surgery, most patients can be completely cured. 2. For kidney cancer, if it is early stage kidney cancer and given surgery to remove, most patients survive for more than 5 years, which is clinical cure. If it is middle and late stage kidney cancer, the possibility of clinical cure is low and most patients survive less than 5 years. Therefore, the prognosis of kidney cancer is related to the patient’s tumor stage and other factors. 3.Kidney pelvis cancer is a malignant tumor, if it can be operated early, most patients have a longer survival time and some patients can be completely cured. If it is in the middle or late stage, the treatment effect is poor and most patients do not have a long survival period. 4. Nephroblastoma (embryonal tumor) is more malignant and most patients are found to have metastasis when they are discovered, so the treatment effect is poor. However, with the combined application of surgery and radiotherapy, some patients can survive for a longer period of time and achieve good treatment effect. 2-3 years without recurrence is considered as clinical cure. If early detection and proper treatment can be achieved, most kidney tumors can be cured. Although kidney cancer is also a kind of malignant tumor, the effect of surgery for early stage kidney tumor is very good, and many patients can achieve the effect of cure. If the kidney tumor develops to advanced stage, then even the best hospital with the best treatment condition will not have the ideal effect.
