Chronic kidney disease (CKD) is a challenge for medicine of the 21^st century because is rare detection and the often concealed course. It is known that kidney transplantation is the best, though not only procedure for the final cure of this illness. The social awareness about transplanting is being shaped by a lot of factors. A chronic disease appearing at close friends and family can be one of them. Examining the influence of having a child with chronic kidney disease on the knowledge and attitudes of parents towards organ transplantation were a purpose of the study. The examination was conducted amongst 120 parents. Examined parents were divided to 3 equal-numerous groups, on account of illness of their child. Parents of children with CKD constituted the first group, second – parents of children with other nephropathies and of urinary system, lastwhereas parents of healthy children. Anonymous authorial questionnaire was applied as a method. Parents of children from CKD in spite of the lower level of education demonstrate greater knowledge about the legal possibility of being living donor of organs and the need to take immunosuppressive drugs after the transplant. Parents of children with CKD definitely accept taking organs from deceased donor. However, parents of children with other nephropathies would more often agree to be a potential donor of organs than parents of children with CKD. Parents of healthy children fundamentally more often had no opinion on taking organs from a relative after her or his death. This group more often think that people do not want their organs after death to be taken because of the distrust the medical staff. The fact that majority of examined persons confirmed the fact that Polish transplantology is not completely free from the phenomenon of the organ trade is also important. Parents of children witch CKD more often think that the greater social awareness of organ transplantation can affect the number of transplants. All groups have similar opinion about actions that can have a positive effect on increasing the number of transplants and institutions which should back the idea of transplantology up in Poland. The study indicated that parents in all examined groups stand for the idea of transplanting organs. Having a child with CKD changes the parents’ attitude. They are more determined to the idea of transplanting. Although their willing of becoming a donor is not stronger than in other groups.
