Peritoneal dialysis and hemodialysis are two different dialysis modalities, and UTI patients need to understand their respective advantages and disadvantages in order to choose the treatment modality that best suits their needs. Peritoneal dialysis, which uses the body’s own natural semi-permeable membrane (peritoneum) for blood purification, was the first of the dialysis modalities to be adopted and is commonly known as belly washing. The peritoneum is a membrane that covers the lining of the abdominal cavity and the layers of organs. A permanent hose is implanted in the patient’s abdomen, and the peritoneal dialysis fluid is exchanged out of the body and then injected with fresh dialysis fluid. The dialysis fluid is changed about 4 to 5 times a day for about 30 minutes each time. Hemodialysis is commonly known as dialysis or dialysis. An arteriovenous fistula must be created, and once the fistula is mature, blood is injected at a fixed rate into an artificial semi-permeable membrane (artificial kidney), which is then purified and returned to the body by a machine. Patients treated in this way must be treated in a hospital, about 2 to 3 times a week, for about 4 to 5 hours each time. Advantages Treatment time is more flexible and can be done at home, at work or any clean place; operation time is greatly reduced; blood pressure is more stable; the possibility of anemia is lower and diet control is more relaxed; no needles are needed and pain is eliminated. The risk of bloodstream infections is reduced, and water and food restrictions are more relaxed. It is not necessary to do it by yourself because it is operated by medical professionals; there is less waste accumulated in the body after dialysis treatment; there is a regular time to go to the hospital every week, which can improve the exchange of experience among patients in preventing and treating diseases. Disadvantages There is a risk of peritonitis; weight gain and elevated triglycerides in the blood may occur; a small amount of protein may be lost. Needles are required each time; anemia is more severe; blood pressure is affected before and after dialysis, which is not good for patients with cardiovascular disease and diabetes; strict dietary control is required; discomfort is more likely to occur before dialysis; the time of dialysis cannot be changed arbitrarily; the risk of bloodstream infection with hepatitis B and C is greatly increased. Currently, the more agreed integrated treatment plan is: in order to protect the patient’s residual kidney function as much as possible, patients with kidney failure should first undergo peritoneal dialysis for about 10 years; after the treatment effect cannot be maintained, then choose hemodialysis; if the kidney function is close to the limit, kidney transplantation treatment will be performed when conditions permit.
