Spanish consensus document for acceptance and rejection of kidneys from expanded criteria donors. Abstract: In the recent years, more than 60% of available deceased donors are either older than 50 yr or have significant vascular comorbidities. This makes the acceptance and rejection criteria of renal allografts very rigorous, especially in cases of younger recipients, and at the same time encourages live donations. In our country, there is a lack of homogeneity in the percentages of use of expanded criteria donor (ECD) allografts between the different autonomous communities. Furthermore, the criteria vary greatly, and in some cases, great importance is given to the biopsy while in others very little. In this study, we present a unified and homogenous criteria agreed upon by consensus of a 10-member Panel representing major scientific societies related to renal transplantation in Spain. The criteria are to be used in accepting and/or rejecting kidneys from the so-called ECDs. The goal was to standardize the use of these organs, to optimize the results, and most importantly to provide for the maximum well being of our patients. Finally, we believe that after taking into account the Panel’s thorough review of specific scientific literature, this document will be adaptable to other national renal transplant programmes. E.

Conflict of interest: None. Accepted for publication 5 August 2014 Kidney transplantation offers superior patient sur- vival quality of life benefits and has proven to be cost-effective compared with dialysis (1, 2). How- ever, the supply of organs from living and deceased donors has been far below the worldwide demand over the last few years (3, 4). The prevalence of patients with end-stage renal disease (ESRD) reached the highest number in our history in 2010, with 1039.4 per million population (pmp); 47.1% of these were transplant patients, maintaining the remaining 52.9% in the different dialysis modali- ties. Assuming that 20% of the new patients com- ing to dialysis are candidates for transplantation, we found a need for more than 26 transplants pmp per year to be able to eliminate the waiting list (5). These data are not unique to Spain, but we face a universal problem, with similar incidences of renal disease in the neighboring countries (ERA/EDTA Registry 2008) (6). The term expanded criteria donor (ECD) was coined in 2002 (7). Such donors are defined as those aged 60 yr and between 50 and 60 yr with at least two of the following criteria: history of hypertension, serum creatinine levels greater than 1.5 mg/dL, or cerebrovascular accident as a cause of death (8). The controversy over the use of the ECD has remained open for as long as different multicenter studies support the idea that these kidneys have poorer long-term survival rates than those of standard kidneys.
