Factors associated with discard of recovered kidneys.

Abstract We reviewed diseased donor (DD) kidney usage at a single Organ Procurement Organization in Southern California to more closely examine factors associated with discard. From 2001 to 2006, 3863 kidneys from 1959 DDs were recovered, but 454 (11.8%) were subsequently discarded. Among the discarded kidneys, 211 (46.5%) were discarded based upon biopsy findings, 19 (4.2%) due to anatomical abnormalities, 16 (3.5%) based on donor quality, and 14 (3.1%) because they were felt to be too old to be pumped. Multivariate logistic regression analysis was performed using significant prognostic factors upon univariate analyses. According to the magnitude of the adjusted odds ratio (AOR), significant prognostic factors for discard were extreme donor age (AOR = 24.1 of age 70–80 years, P P P P 40 vs others, P = .006), glomerulosclerosis (GS) > 20% (AOR = 5.94 vs GS 0%–5%/no biopsy, P P = .003), abnormal anatomy (AOR = 2.7, P P 20% was associated with the highest likelihood of discard. A high final resistance increased the likelihood of discard as well. In conclusion, these findings may help to set the groundwork toward a more uniform approach to organ utilization in donor service areas.
