Table 3.
Causes of KDR per donor age decades
| KDR and KDR causes | 50–59 yr (n=188), % | 60–69 yr (n=587), % | 70–79 yr (n=604), % | ≥80 yr (n=110), % | Total (n=1489), % | P Value |
|---|---|---|---|---|---|---|
| Organ recovered and transplanted | 84.6 | 81.8 | 78.1 | 51.8 | 79.4 | <0.001 |
| Organ recovered but not transplanted (KDR) | 15.4 | 18.2 | 21.9 | 48.2 | 20.6 | <0.001 |
| KDR causes | ||||||
| Suspected donor neoplasia or other comorbidities | 0 | 2.7 | 2.6 | 1.8 | 2.3 | 0.15 |
| Organ macroscopic appearance or anatomic anomalies | 4.8 | 7.2 | 10.3 | 20 | 9.1 | <0.001 |
| Preimplantation kidney biopsy | 3.7 | 5.1 | 4.6 | 11.8 | 5.2 | <0.001 |
| Technical problems | 4.3 | 0.9 | 2.3 | 3.6 | 2.1 | <0.001 |
| No available recipients | 2.1 | 1.8 | 2.1 | 10.9 | 2.6 | <0.001 |
| Others | 0.5 | 0.5 | 0 | 0 | 0.3 |
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.
