Histology. A: representative periodic acid Schiff-stained histology images. Preserved architecture was observed in all the groups. Focal minor tubular injuries (blue arrow) were only observed in the SKT group. B: kidney injury scores. Based on the percentage of necrotic tubules, the SKT group exhibited the very mild tubular injury. There was no structural abnormality detected in Sham, nephrectomy, and DKT groups (*P < 0.01 vs. other groups; n = 6). DKT, dual-kidney transplantation; SKT, single-kidney transplantation.
