Further observations on histological changes at the ureteroileal junction in ileal conduits.

摘要: Seventy-two ureteroileal anastomoses taken from ileal conduits removed 62 patients were examined histologically to characterize the range of mucosal and stromal changes at these sites. All 72 demonstrated variable amounts subepithelial chronic inflammation fibrosis. Other histological features included: cystic spaces lined by transitional epithelium (N = 29; 40%; average diameter 1.2 mm); mixed intestinal/transitional 5; 7%; 0.77 cystically dilated intestinal glands 21; 29%; 0.24 mm). The latter associated with overgrowth epithelium, which had prevented mucus drainage. Twenty-one (29%) pools no epithelial lining (average mm), polypoidal protrusions into lumen anastomosis found containing 4; 6%; 1.4 transitional-lined cysts 2.2 intestinal/transitional-lined 2; 3%; 2.5 Focal rupture interstitial pooling was not uncommon, marked dystrophic calcification in 1 case within a large collection extracellular mucus. This series confirms that inflammation, fibrosis, glandular are common occurrences Subsequent gland may result sizable accumulations mucus, rarely calcification.
