Urothelial histopathology surrounding XXXX .

@entity1 @entity2735 @entity5 @entity1373 @entity189 @entity2526 @entity854 @entity150
We studied the histological condition of the urothelium surrounding @entity150 in 65 @entity1 who underwent partial resection of the bladder. These examinations showed that @entity854 were always present, i.e. a direct transition from @entity5 to normal urothelium was never observed. The histological alterations were divided into 10 classes and their relative positions were determined with respect to the primary @entity5 site. The extension of urothelial alterations around the @entity5 and the severity of the alterations were related to the grade of the primary @entity5 . @entity2526 were usually found next to the @entity5 , whereas hardly altered urothelium was located more distant to the primary @entity5 site. We found three atypical types of @entity1373 more frequently than simple types of @entity1373 in the vicinity of high grade (G3) @entity189 . Total @entity1373 of basal cells was more frequent than @entity1373 . Furthermore, @entity2735 ( @entity2735 ) with a persisting layer of normal superficial cells tended to be relatively far from the primary @entity5 site, whereas @entity2735 without normal superficial cells was usually next to the primary site. Two models for the pathogenesis of the urothelial alterations surrounding @entity150 are briefly discussed.
