Introduction: Transplant renal artery stenosis (TRAS) is a heterogeneous disorder with different subtypes and aetiologies, which include traditional cardiovascular and transplant specific risk factors. Whether the increasing use of extended criteria donors, who have a higher incidence of intrinsic cardiovascular risk factors will impact on the incidence of TRAS is not known. The aim of this study is to determine if a high UK kidney donor risk-index (UKKDRI) score is associated with TRAS.
Methods: We performed a retrospective analysis of all transplants performed at our centre between 2005 and 2015. 209/1479 (14.1%) of all patients had TRAS proven by formal angiography.
Results: TRAS prevalence was significantly higher in deceased donors (DD) compared with LD, 152/209 (72.7%) of TRAS developed in DDTx recipients, p<0.0001. The mean time to TRAS diagnosis was 3.5±3.6 months. Demographics were available on 150 deceased donors with TRAS and these were compared with 605 TRAS negative deceased donors.

| SCD/ECD status | SCD | 54 (36.0) | 336 (55.5) | <0.0001 |

| UKKDRI score | High | 81 (53.3) | 213 (35.2) | <0.0001 |
Discussion: A high risk UKKDRI score may enable identification of patients at risk of developing TRAS and knowing donor characteristics may allow a focused screening strategy for TRAS post deceased donor transplantation.
