Dialysis in the renal cancer

More frequent neoplasm of the kidney is the epithelial cancer. Surgical tumor resection with partial or radical nephrectomy is the essential means of the treatment. The patients not-qualified for the surgery are treated with immuno-l and/or chemiotherapy. Each of the diagnostic-therapeutic stage, especially radiodiagnostics with hyperosmotic contrast medium and follow surgery, could be complicated with acute renal failure: prerenal (as the result of the hypovolemia before and during operation, massive bleeding), drug-induced (immuno- and chemiotherapy) and extrarenal as a result of the cancer infiltration with impairment of the urine outflow. Especially the aged patients, with previous impaired renal failure are threatened. Prevention of this complication contains the monitoring renal function parameters and it must be continued during the all surgical-
-oncological intervention, with taking into the consideration ”renal risk” of the successive stages of the treatment. In detail the fixed stage of the acute renal failure requires of the control in the center with dialysis. The dialysis is necessary in the case of emergency, because of the hyperpotasemia, hypervolemia, acidosis and hyperazothemia. In same cases the decision about chronic dialysis programme is also undertaken. The choice of the method of the dialysis always depends on clinical patient condition and accessible dialysis method in the center where the patient is treated.
