How long you can live in advanced kidney failure varies from person to person. Generally, advanced renal failure refers to the stage of uremia, which is commonly referred to by the people. Before the popularity of dialysis, the survival time of patients with advanced renal failure was very short, and they were likely to die within a few months, or at most within a year. Later, with the expansion of medical insurance and the introduction of uremia into major medical insurance, most patients with advanced renal failure survived between 5-10 years after dialysis, with some patients surviving longer, up to 50 years in the literature. However, it is also related to whether the patient has serious complications, for example, if the patient develops serious complications such as cerebral hemorrhage, myocardial infarction, or severe heart failure during the process of dialysis or between dialysis, the patient may die at any time. In addition, exactly what causes uremia may also affect the prognosis of patients, such as advanced renal failure caused by diabetic nephropathy and ANCA-associated small vessel vasculitis, where patients have a relatively short survival time, and advanced renal failure caused by primary glomerular disease, where survival time is relatively long.
