title: [Post-transplant kidney from C-III donation after cardiac death of children: a clinicopathologic study of 20 cases].
abstract: OBJECTIVE
  To study the clinical and histopathologic features of post-transplant kidney biopsy tissues from pediatric C-III donors.
  
  
  METHODS
  The clinical and pathologic features of 20 cases (22 case-times) of renal transplant biopsies from pediatric cadaveric donors were analyzed by light microscopy and immunohistochemistry according to the Banff system of working classification of renal allograft pathology. Biopsies were compared to those from adult C-III donors and adult cadaveric donors.
  
  
  RESULTS
  Sixteen cases (72.7%) showed renal allograft drug toxicity damage by Tacrolimus, seven cases (31.8%) showed degeneration and necrosis of renal tubular epithelial cells, four cases (18.2%) showed T cell-mediated acute rejection and six cases (27.3%) showed renal interstitial inflammation. There were two cases (9.1%) of renal dysplasia and one case (4.5%) of renal infarction. There was insufficient evidence for diagnosis of renal allograft nephropathy. Compared to post-transplant kidney from adult C-III donors, the proportion of drug toxicity damage was higher (P<0.05). Compared to post-transplant kidney from adult cadavers, the proportions of drug toxicity damage, degeneration and necrosis of renal tubular epithelial cells were higher (P<0.05) while the proportion of acute rejection was lower (P<0.05).
  
  
  CONCLUSIONS
  The pathologic changes in the post-transplant kidneys from pediatric donors are different from those from adult donors. Optimal long-term outcome can be accomplished by effective treatment based on timely or procedural biopsy.
