Abstract

We compared the roles of urinary cytology and flow cytometric DNA analysis in the evaluation of 26 patients with transitionsl cell carcinoma of bladder from March 1989 to April 1991. When carcinoma was present at the time of specimen collection it was detected by cytology in 65.4 percent and flow cytometric DNA analysis in 73.1 percent. Combination of flow cytemetric DNA analysis and urinary cytology increased the diagnostic yield to 88.5 percent Flow cytometric DNA analysis was slightly more sensitive than urinary cytology for the detection of abnormalities in specimen from low stage. high grade. small size. small number and recurrent cancer but no statistically significant difference was identified. When used in conjunction with urinary cytology. urine flow cytometric DNA analysis was valuable procedure in the diagnosis and follow up of patients with bladder cancer.
