[Use of flow cytometry in the diagnosis of bladder tumor].

Bladder irrigation specimens from 42 patients, in which 10 cases were benign tumor or bladder inflammation and 32 cases transitional cell carcinoma, were analysed by flow cytometry (FCM). Compared with routine cytological examination, their positive rates were 87.4% and 62.5% respectively. The difference was statistically significant. FCM is more sensitive and specific than the conventional cytology in detection of bladder tumor.
