In the past, most patients on peritoneal dialysis would develop severe abdominal infections within 3 years of dialysis due to inadequate technology and consumables, and would have to terminate peritoneal dialysis, which could even be life-threatening. However, the current technology of peritoneal machine dialysis is becoming more and more mature, and the survival time of patients is becoming longer, which can reach more than 10 years. However, in most patients, peritoneal dialysis does not reach 10 years, the peritoneal function is completely lost, and the role of eliminating toxins and excess water from the body is not achieved, so it is necessary to switch to hemodialysis in time. The current technology of hemodialysis is relatively mature, and if there are no complications and if hemodialysis is performed with sufficient regularity, patients can survive for more than 20 years. Currently, the longest surviving hemodialysis patient in the world has survived for 40 years.
