The life expectancy after peritoneal dialysis for uremia is generally difficult to count, if it does not cause complications, the five-year survival rate is relatively high, with the severity of the disease and the individual’s physical fitness, can not be generalized. Dialysis treatment for uremic patients generally includes hemodialysis treatment as well as peritoneal dialysis treatment. Therefore, peritoneal dialysis is one of them, which can help maintain the balance of the patient’s internal environment and prolong the patient’s life by facilitating the elimination of excess water and metabolic wastes from the body. This kind of peritoneal dialysis is prone to peritonitis. However, nowadays, with the improvement of the technology of peritoneal dialysis, this complication of peritonitis is decreasing, which helps the patients to enhance their survival time, and even have the possibility to survive for a long time. The five-year survival rate is relatively high if the peritoneal dialysis patient has no significant complications. In addition, uremia is more harmful, so patients need to be diagnosed as soon as possible after the diagnosis of regular hospitals, and actively cooperate with specialists for treatment.
