  • Percentages are calculated on the total amount of organ recovered. Preimplantation biopsy indicates Karpinsky score ≥7. Technical problem indicates prolonged cold ischemia time, procurement iatrogenic lesions, etc. Donor other comorbidities indicates hepatitis C serology positive, bacteremia, etc. KDR, kidney discard rate.
