    Abstract:
    BACKGROUND: Use of expanded criteria donor (ECD) grafts seeks to solve the organ shortage. We investigated the current status of donor selection and transplantation outcomes. METHODS: We retrospectively analyzed 791 kidney transplantations performed between 1997 and 2009. An expanded criteria deceased donor (ECDD) was defined as an individual who fulfilled the United Network for Organ Sharing criteria or, the Nyberg criteria. An expanded criteria living donor (ECLD) was determined by fulfillment of 1 or more of 5 criteria. RESULTS: Deceased and living donor kidney transplantations were performed in 228 (28.8%) and 563 (71.2%) cases, respectively. Forty-three cases (18.9%) belonged to the ECDDs. The ECDD group showed a lower posttransplantation 1-year estimated glomerular filtration rate (eGFR) than that of the standard criteria deceased donor (SCDD) group (70.7 ± 19.2 vs 48.6 ± 11.5; P < .001). The ECDDs were allocated to older recipients or recipients with more HLA mismatches than SCDDs. The number of ECLD cases was 173 (30.7%). The proportions of each medical abnormality of living donors were as follows: age older than 60 years (0.5%), hypertension (2.5%), obesity (2.1%), low eGFR (25.9%), proteinuria (0%), and microscopic hematuria (1.4%). The ECLD group showed a lower posttransplantation 1-year eGFR than that of the standard criteria living donor (SCLD) group (66.9 ± 16.0 vs 58.3 ± 11.2; P < .001). Graft survival was not different among the donor types (P = .518). CONCLUSIONS: eCDs were 27.3% of the total kidney donors. Posttransplantation 1-year eGFR was lower in the ECD group. However, there was no difference in the graft survival among the different donor types.
