Fig. 3From: A comparative study on the efficacy of a retrograde perfusion technique and an antegrade perfusion technique for donor kidney recovery in transplantation in pigsBoth retrograde perfused kidneys (a) and antegrade perfused kidneys (b) have minimal interstitial, tubular edema and endothelial cell swelling with good preservation of renal architecture at 2–4 h in cold storage (hematoxylin and eosin staining, 20×). Retrograde perfusion (c) resulted in glomerular shrinkage with effusion and antegrade perfusion (d) resulted in glomerular shrinkage at the end of 24 h in cold storage (hematoxylin and eosin staining, 40×)Back to article page
