The relationship between nurses and peritoneal dialysis (PD) patients begins from the time of the selection of medical treatment for renal replacement therapy. There are various roles in this field that involve nurses, not only in providing technical guidance to patients but also in relaying dietary restrictions including those on fluid and diet, in providing information on public welfare for dialysis patients and in fostering interactions between the patient and doctors, nutritionists, social workers and medical support staff. The nurse plays an important role in the success of a PD training program. Only highly trained nurses should carry out PD training. The nurse trains the patient or a family member as a helper to perform PD. The ultimate goal is to make a plan to help the patient maintain his or her general condition and expand the quality of life by self-care. However, the most important role of nurses is to display empathy to the patient, that is, to put themselves in the patient's position, to foster an ongoing interaction between themselves and the patient and to listen to the patient and understand what is in the mind of the patient.
