Comparison of urine liquid-based cytology and conventional cytology in diagnosis of bladder cancer

Objective:To evaluate the clinical value of urine liquid based cytology and conventional cytology in the diagnosis of bladder cancer.Methods: Urine samples from 208 patients with suspected badder caner were detected by liquid based cytology and conventional cytology respectively,results were compared to histopathology.Results: Total of 108 times urine samples from 208 patients of liquid based cytology were detected in cancer cells,51 times were suspicious cancer cells,32 times were atypical cells;102 times of conventional cytology were detected in cancer cells,39 times were suspicious cancer cells,52 times were atypical cells.The sensitivity for liquid based cytology and conventional cytology was 71.7 %,65.0% respectively;both of specificity was 99.3%.Conclusion: Liquid based cytology facilitate a more accurate diagnosis than conventional cytology in diagnosis of bladder cancer,the quality of liquid based cytology smear is better than conventional cytology.
