In 104 patients who were suspected of having prostatic carcinoma, we reevaluated the clinical validity of exfoliative cytology utilizing prostatic fluid obtained by a speciallydesigned catheter devised by Ichijo. Of 29 patients who had been histologically diagnosed as having prostatic carcinoma, 15 were cytologically positive and eight were strongly suspected to have a carcinoma. Therefore, diagnostic sensitivities were 52%(15/29) and 79%(23/29 ; including cases with class IIIb). In addition, in the two of five patients who were cytologically positive but histologically negative, subsequent follow-up biopsy ultimately confirmed prostatic carcinoma. Thus, we consider this method to be a simple and potentially useful method for early detection of prostatic carcinoma.
