Whether it is diabetes, nephritis, high blood pressure, or other causes leading to kidney failure, it may eventually progress to uremia. Patients with such conditions need dialysis or a kidney transplant to survive. Generally, patients undergoing any type of dialysis do not experience significant pain symptoms.

Dialysis can be divided into hemodialysis and peritoneal dialysis, both of which use artificial methods to remove metabolic waste from the patient's body and maintain the stability of the internal environment. These methods generally do not involve significant traumatic procedures, so they mostly do not cause notable pain. However, patients undergoing hemodialysis may need temporary needling each time, which causes minimal trauma and typically does not result in severe pain or significant discomfort.
