The Banff Preimplantation Biopsy Working Group have developed new consensus criteria for the histopathological evaluation of donor kidney biopsy samples prior to transplantation. They report good to fair reproducibility of semi-quantitative scores for glomerulosclerosis, arterial intimal fibrosis and interstitial fibrosis in frozen wedge biopsy samples. Quantification of number of glomeruli was similar in frozen wedge and core biopsy samples but needle biopsy samples showed worse intraclass correlation for glomerulosclerosis, interstitial fibrosis and tubular atrophy. The new criteria include a consensus evaluation form to help to standardize the reporting of histopathological lesions in preimplantation kidney biopsy samples.
