Ureter. (A) Intact epithelium (Lesion grade 0). (B) Loss of epithelium affecting less than half of the mucosa; focal loss (Lesion grade 1). (C) Intact epithelium of the ureter; lamina propria showing fibrosis extending towards the muscle layer (arrows). (D) In total, denuded mucosa; total loss of epithelium (Lesion grade 3). *Indicates moderate connective tissue edema of the lamina propria.
