Successful outcomes with transplanting kidneys from deceased donors with acute kidney injuryon temporary renal replacement therapy.

BACKGROUND AND

OBJECTIVES

We aimed to determine outcomes with transplanting kidneys from deceased donors with severe acute kidney injury requiring acute renal replacement therapy (RRT).

MATERIALS AND

METHODS

A total of 172 recipients received a kidney from donors with acute kidney injury stage 3 (AKIN3) requiring RRT. We compared the study group to 528 recipients who received a kidney from donors with AKIN stage 3 not on RRT and 463 recipients who received < 85% Kidney Donor Profile Index (KDPI) AKIN stage 0 kidney.

RESULTS

The study group donors were younger compared to the 2 control groups. Despite higher DGF in the study group, the length of hospital stay and acute rejection were similar. Death censored graft survival (96% AKIN3-RRT vs. 97%AKIN3 no RRT vs. 96% KDPI < 85% AKIN0, P = 0.26) and patient survival with functioning graft at 1 year (95% across all groups, P = 0.402) were similar. The estimated glomerular filtration rate were similar across the 3 groups after first month. Interstitial fibrosis and tubular atrophy score ≥ 2 on protocol biopsy at time 0, 4 and 12 months were similar. Primary nonfunction was rare and associated with high KDPI.

CONCLUSIONS

Transplanting selected kidneys from deceased donors with AKIN3 requiring RRT is safe and has good outcomes.
