A rapid and simple cytologic screening technique for fresh urine specimens stained with toluidine blue was described. As for the validity and description of cell structures, the accuracy of urine cytology with this procedure is very simillar to that of Papanicolaou technique. Utilizing this simple technique, a hospital population was screened for urinary tract cancer from specimens sent for soutine urinalysis. In this study of 16062 fresh urine sediments selected at random from non-urologic patients, a total of three histologically proven bladder cancer were detected. The detection rate of one bladder cancer in 5000 individuals makes this simple technique worthwhile in mass screening. On the other hand, another study of 730 urine sediments from all of urological patients, five were proved to have malignancy in genitourinary tract including three bladder cancer, one urethral cancer and one prostate cancer. Two of them were proved to be carcinoma in site by the histological examination and they were all, unsuspected in routine examination.
The results emphasize the usefulness of this simple screening technique in combination with clinical urinalysis and cytology for early detection of urinary malignancy.
