Chronic kidney disease is becoming an increasingly common problem in modern society, and the treatment of patients with impaired renal function requires the cooperation of members of a multidisciplinary team. Through the content of this final paper, idea is tried to emphasize the importance, the multiple role of the nurse/technician in the care of patients with impaired renal function. The nurse/technician spends the most time with the patient in the process of treating the patient and in this way can provide the patient with the necessary support. Health care of patients implies the implementation of certain medical - technical procedures. In this way, they participate in the preparation of patients for the catheter implantation procedure. The role of the nurse/technician is to observe the patient's condition during and after the introduction of the catheter, and to care for the patient after the procedure. Nursing care after discharge of the patient from the hospital, is carried out continuously, continues at home of the patient. Healthcare includes the possibility of telephone consultation of the patient with a healthcare professional, and ensures availability during 24 hours. It includes health care with its peculiarities, education of the patient and his family providing professional support. Education is an extremely important factor that ensures a greater degree of independence of the patient in the implementation of substitution treatment, and thus seeks to influence the higher quality of life of patients. The most commonly chosen treatment methods are hemodialysis (HD), peritoneal dialysis (PD) or kidney transplantation. This paper seeks to emphasize the still underrepresented method of substitution treatment in the world and in our country, and that is peritoneal dialysis. Although it has significant economic savings compared to hemodialysis as well as quality equal therapeutic effect, the method of peritoneal dialysis is still relatively rarely used and there is a lot of room for justified popularization of this method.
