N Venumadhav, D Pramod Kumar, N Ramya and N Rajendranath
Histological features of goat Renal Collecting System (RCS) revealed collecting tubules lined by simple cuboidal epithelium forming papillary ducts deep in medulla. Epithelium changed to transitional type at the tip of renal crest which had numerous papillary duct openings. Renal pelvis lined by transitional epithelium. Sub epithelial tissue of renal pelvis consisted thick wavy bundles of collagen fibres. Thickness of renal pelvis wall decreased towards the edges of renal crest. Inner mucosa of ureter showed 5 to 8 folds projecting into the lumen giving it a star shaped structure. Transitional epithelium of 8 to 10 cell layers lined the ureter below which was propria-submucosa. Tunica muscularis of ureter had three layers of which the inner layer was inconstant, whereas the middle layer was distinctly circular and continuous. Renal pelvis and ureteral segments showed mild reaction to PAS and PAS-AB which was restricted to surface lining of epithelium and basement membrane.
