Kidney cancer generally does not require kidney transplantation, but radical nephrectomy treatment, which is required to remove the maximum tumor load in the body to achieve clinical cure. The scope of resection includes the kidney and all its cancerous tissues, as well as the fat and fascial tissues around the kidney, and lymph node dissection is necessary to minimize the probability of recurrence after surgery. Generally, after radical resection of unilateral kidney cancer, the contralateral kidney does not need to be replaced as long as it is normal, and the contralateral kidney can fully maintain the body’s water and electrolyte metabolism and ensure the smooth elimination of toxins from the body. However, if it is bilateral kidney cancer, we can consider kidney transplantation after bilateral kidney cancer resection, or maintenance dialysis after surgery to remove the tumor to the maximum extent and use dialysis or transplanted kidney to maintain the normal body water and electrolyte metabolism, but the survival quality of patients after such surgery is relatively poor.
