As a kidney specialist, I can provide you with information on the survival rates for individuals with kidney failure. It's important to note that the duration of life with kidney failure can vary greatly depending on the type of kidney failure, the underlying cause, the severity, and the treatment options available. In the case of acute kidney failure, also known as acute renal failure (ARF), the renal function declines rapidly, which can lead to serious metabolic disturbances. If the condition progresses to a point where the person stops producing urine, a state known as anuria, the survival time can be quite limited. Historically, without dialysis, it was believed that survival beyond 2 to 3 weeks was unlikely. However, with modern medical interventions such as dialysis and critical care, survival rates have improved significantly, and patients can survive for longer periods while awaiting recovery or a kidney transplant. For chronic kidney failure, also known as chronic kidney disease (CKD), the progression is much slower, and patients can live for many years with the condition, especially with appropriate medical care and lifestyle modifications. The lifespan can be influenced by how well the disease is managed, the stage of CKD at diagnosis, and whether the patient receives treatments such as dialysis or a kidney transplant. In summary, while acute kidney failure can be life-threatening in a matter of weeks without treatment, chronic kidney failure allows for a longer survival time with proper management. Advances in medical care have greatly improved the outlook for patients with kidney failure. read more >>

In the case of acute renal failure the renal function declines rapidly within hours or days giving rise to serious metabolic disturbance. If that state continues to the point that the person is no longer producing urine, which is known as oliguria, it is unlikely that the person could survive longer than 2 to 3 weeks.read more >>
