Kidney failure with anuria is not possible to judge how long the life expectancy is, if not actively treated, there is a risk of sudden death at any time, if actively treated, there is a possibility that the patient can get a very long time to live, and even life expectancy can be unaffected. For patients with renal failure without urine, renal function has basically disappeared, at this time, the ability to drain and detoxification are very poor, water accumulation in the body, leading to edema, not only subcutaneous edema, and even visceral edema, as well as the emergence of pleural fluid, ascites, pulmonary edema, pericardial effusion, cardiac failure, etc., seriously affecting the body’s health, and at any time endangering the lives of the patients. Patients with renal failure with anuria can replace normal kidneys to excrete toxins and wastes in the body if they actively undergo renal replacement therapy such as hemodialysis, which may give them a long survival time if they are effectively dialyzed for a long period of time; and if they undergo a suitable renal transplantation, it is possible to get a long survival time without even affecting their life expectancy. If kidney failure with anuria occurs, it is recommended to go to the hospital for further consultation and follow the doctor’s instructions for active treatment to avoid delaying the condition.
