For patients with uremia, kidney replacement is better compared to dialysis. A typical characteristic of patients with uremia is the loss of the ability to detoxify and drain. Patients have two options to survive: the first is continuous hemodialysis, which removes excess toxins and water from the body with the help of a dialysis machine. However, dialysis machines do not remove toxins sufficiently, and the amount of toxins removed each time is only 1/10 of the normal kidney, which means that most of the toxins are still in the body and still cause damage to various organs. The second treatment method is kidney transplantation, which is commonly known as kidney replacement. After kidney transplantation, the transplanted kidney can have all the functions of its own kidney, which not only can remove toxins and water more adequately, but also can produce erythropoietin to correct anemia. Therefore, for patients with uremia, it is better to have a kidney transplant if possible.
