Cytologic Grading of Urothelial Tumors

摘要: The critical difference between a cytologic and histopathologic examination is that the evaluation disregards topographic architectural tissue changes. While histology can additionally evaluate “third dimension” of supracellular architecture relationship cells to adjacent structures, cytology based solely on analysis cell morphologies. This relative information deficit compared with balanced by noninvasiveness cytology, its simplicity, low cost, option repeating as often desired.
