The evolution of donation after circulatory death renal transplantation: a decade of experience

Background. This study compared long-term outcomes of renal transplantation from donors following donation after circulatory death (DCD) with those following donation after brain death (DBD) from one of the largest centres in the UK. Method. Recipients of renal transplants from deceased donors between 2002 and 2014 were identified from a prospectively maintained database. Outcomes were compared between DCD (468) and DBD (905) donors and between standard criteria donors (SCDs) and extended criteria donors (ECDs). Results. Graft survival (GS) and patient survival (PS) from DCD and DBD donors were comparable up to 10 years (GS: 61 versus 55%, P = 0.780; PS: 78 versus 71%, P = 0.285, respectively). Graft function was comparable after 3 months. GS and function were worse in the ECD groups, with no difference between EC-DBD and EC-DCD. PS in the ECD groups was worse than the SCD groups and PS in the EC-DCD group was worse than in the EC-DBD group. DCD donors were an independent risk factor for delayed graft function. Post-operative complications and EC-DCD donation were independent risk factors for reduced GS and PS. Conclusion. This study supports the use of DCD renal grafts with comparable long-term survival and function to DBD grafts. The use of EC-DCD grafts is justified in selected recipients and provides acceptable function and survival advantages over dialysis.
