RESUMO
ABSTRACT Among renal replacement therapies, preemptive kidney transplantation (PKT) presents the best clinical, social, and economic results. However, it is still infrequently chosen as first therapy for patients with irreversible kidney failure. Initiatives in different parts of the world were developed to identify the reasons why PKT is still not widely used and to facilitate the access of patients with end-stage kidney disease to the advantages associated with it. This article addresses the main advantages and difficulties of PKT and discusses when it should be indicated and how to prepare potential recipients for PKT.

No entanto, ainda é raramente escolhido como primeira terapia para pacientes com falência renal irreversível. Foram desenvolvidas iniciativas em diferentes partes do mundo para identificar as razões pelas quais o TRP ainda não é amplamente utilizado e para facilitar o acesso de pacientes com doença renal em estágio terminal às vantagens associadas ao mesmo. Este artigo aborda as principais vantagens e dificuldades do TRP e discute quando ele deve ser indicado e como preparar potenciais receptores para o TRP.
RESUMO
PURPOSE: There is increasing consideration about the preemptive transplantation, transplantation without any preceding dialysis, as a one of options of a renal replacement therapy (RRT). This study evaluates a beneficial effect on recipient and allograft survival of preemptive transplantation and compares the outcome to that according to the dialysis modality and duration. METHODS: All patient who had received a kidney transplant from a living donor in the Seoul National University Hospital (SNUH) between January 1990 and October 2004 are included in this retrospective study. Patients were subdivided into three groups; preemptive transplant group (group 1, n=47), hemodialysis group (group 2, n=307) and peritoneal dialysis group (group 3, n=52). RESULTS: The characteristics of each groups were not statistically different except recipient age. Ten-year patient survival was 97.8% in PE group, but is not significantly higher than in HD (89.4%) and in PD (90.7%) groups. However, 10-year graft survival was higher in PE group than in HD group (p<0.05; 100%, 74.7% respectively). The differential effect of pretransplant dialysis duration on graft survival was prominent if the patients had been on the pretransplant dialysis for more than 42 months (p<0.05; 10-year graft survival; PE, 100% and dialysis more than 42 months, 77.9% respectively) Compared with HD group as a pre-transplant dialysis modality, PD group showed better patient and graft survival rate, but not statistically significant. CONCLUSION: Depending on the above results, we may suggest PE or PD being a superior pre-transplant modality than HD. And we should be considerate of choosing treatment modality and duration before transplantation.
