Detection of urinary cancer with urinalysis sediment.

Examination of urinalysis sediments stained with toluidine blue from 1,208 men and women more than 40 years old revealed 58 abnormal specimens. Of these specimens 5 were positive with a routine cytologic examination and histopathologic confirmation. This detection rate of 1 bladder cancer in 1,000 examinations makes this simple examination worthwhile, the preparation of which has been done mainly in clinical microscopy.
