The best and most comprehensive form of renal replacement is the successful implantation of a healthy donor kidney. However, worldwide there are not enough donor organs available. Sometimes, important medical or personal reasons also make a kidney transplant impossible. Chronic kidney failure therefore requires – at least temporarily – treatment using an “artificial kidney”. This treatment is known as “dialysis”.

Various types of dialysis treatment have proven effective. If an actual “artificial kidney” is used, a filter cleans the blood in a process called hemodialysis. However, the peritoneum, or lining of the abdomen, is also available as a natural filter. It is used in peritoneal dialysis. The most important forms of renal replacement therapy will be explained in greater detail shortly.
