After renal failure patients need renal replacement therapy, and the most common treatment option is dialysis. For the life expectancy of patients who start dialysis, with the current level of dialysis, there are about 15-20 years of survival, and there is a better quality of life. There are two types of dialysis: hemodialysis and peritoneal dialysis. Examples are as follows: 1. Hemodialysis requires three times a week, about four hours each time, and removes excess water and toxins from the body through filters and hemodialyzers; 2. Peritoneal dialysis involves placing peritoneal dialysis tubes into the abdominal cavity of the human body, and exchanging toxins and fluids through the peritoneal membrane and the greater omentum of the human body. There are no obvious advantages and disadvantages of these two types of dialysis, and it is mainly necessary to choose according to the specific conditions of the individual. In addition to regular dialysis, regular oral medication is also needed to prevent kidney diseases and dialysis-related complications.
