The life expectancy after dialysis for uremia is about 10-30 years, and the median survival time is about 15 years, but there are great individual differences. Various kidney diseases progress gradually, and once they reach the stage of uremia, the kidneys lose their own functions, and then they need to resort to hemodialysis for long-term survival. Although dialysis can maintain the basic physiological needs without heart failure, cerebral edema, hyperkalemia and so on. However, the removal of toxins by dialysis is not sufficient, and the toxins removed each time is only equivalent to 1/10 of the normal renal detoxification, which means that most of the toxins still remain in the body, causing damage to various organs of the body, which will affect the survival life of the patient. The survival time of uremia dialysis is about 10-30 years, but some dialysis centers may have a higher quality of dialysis and choose a variety of blood purification methods, the patient’s survival time may be longer. Therefore, if the patient can find a suitable kidney source and the financial situation permits, it is recommended to have a kidney transplant, so that the patient may live longer.
