Identification of donor factors predisposing to high discard rates of cadaver kidneys and increased graft loss within one year posttransplantation--SEOPF 1977-1982. South-Eastern Organ Procurement Foundation.

Abstract

From 1977 to 1982, the South-Eastern Organ Procurement Foundation (SEOPF) conducted a prospective study to determine the fate of all cadaver kidneys retrieved by member institutions. During the study period, 6152 kidneys were retrieved, 1264 being discarded. Donor factors predisposing to wastage included AB and A blood groups, donor age greater than 30, hospitalization greater than 3 days, serum creatinine greater than 2.0 mg%, average systolic blood pressure less than 80, last-hour urine output less than 100 ml, proteinuria, heart not beating at time of nephrectomy, and kidneys not removed en bloc. Donor factors affecting graft survival rate at one year include age, length of hospitalization, last-hour urine output, and changing serum creatinine. The data suggest that certain donor kidneys are less likely than others to be transplanted depending on donor characteristics and retrieval practices. Furthermore, some of these factors have a negative impact on long-term success when kidneys are transplanted.
