Abstract:
BACKGROUND: Urine cytology is an important test in the screening of urothlelial neoplasms. The conventional smear (CS) method of testing urine samples has a low sensitivity, approximately 50% result accuracy for detecting urothelial carcinomas, while liquid-based cytology (LBC) has much improved diagnostic accuracy, sensitivity, and specificity. The aim of this study was to compare the morphologic features and diagnostic efficacy of CellprepPlus(R) LBC with those of CS for urine cytology. METHODS: A total of 713 cases of urine specimens collected from November 2009 to September 2010 were included. All specimens were divided equally for the preparation of CellprepPlus(R) LBC and CS for each case. RESULTS: CellprepPlus(R) revealed more cellularity, a cleaner background and better cytomorphologic features, but it showed a less intact architectural pattern compared to that of CS. Of the 88 histologically confirmed cases, the diagnostic sensitivity for CellprepPlus(R) was 50% and higher than the 37.5% for CS. The specificity of both preparations was 100%. CONCLUSIONS: The CellprepPlus(R) showed an improved quality of slides and provided better diagnostic accuracy, thus CellprepPlus(R) could be a first-line screening tool in urinary tract cytology.
