OBJECTIVES:
Simultaneous liver-kidney transplantation (SLKT) improves survival for liver transplant (LT) recipients with renal dysfunction (RD); however, simultaneous transplant risks KT futility in high acuity recipients. We sought to analyze effects of delayed KT through pulsatile cold perfusion pumping on SLKT outcomes.
METHODS:
Retrospective dual center analysis (UCLA [n=91], TMH [n=67]) of adults receiving SLKT from 2008-16.

| Post-Tx LOS (days) | 23 (1-75) | 30 (1-157) | 0.03 |
| Post-Tx HD Independence | 98% (57) | 89% (89) | 0.03 |
| Kidney Primary Nonfunction | 2% (1) | 12% (12) | 0.02 |
RESULTS:
58 SLKTs (37%) underwent delayed transplant of pumped kidneys (pSLKT). 100 (63%) received non-pumped kidneys (npSLKT). Median MELD was 34 for pSLKT and 35 for npSLKT (p=ns). PreTx, pSLKT had longer ICU stay and greater vasopressor use, but were otherwise similar to npSLKT (Table1). Despite this, 1-, 3-, and 5-yr survival were significantly greater for pSLKT (p=0.04, Figure1). pSLKT recipients demonstrated a decreased PostTx length of stay (p<0.001) and KT primary nonfunction (p=0.018) compared with npSLKT (Table1).
CONCLUSIONS:
In high acuity LT recipients, delayed KT by 24 hours allows recipient hemodynamic stabilization. Kidney pumping improves survival and decreases futility. Outcomes are similar to allograft survival for KT alone, despite LT recipient acuity. This suggests allowances of SLKT allocation should continue to avoid unnecessary death following LT from ongoing RD.
