title: Urinary cytology as a test in mass screening.
abstract: A rapid and simple cytologic screening system for urinary tract cancer stained with toluidine blue was described. Utilizing this system, a hospital population was screened for urinary tract cancer from specimens sent for routine urinalysis. In this study of 16,062 fresh urine sediments selected at random from non-urologic patients, three cases histologically proven bladder cancer were detected, leading to the detection rate of one bladder cancer in 5,000 individuals. The results emphasizes the usefulness of this simple screening technique in combination with clinical urinalysis and cytology for early detection of urinary tract malignancy.
