Detection of bladder tumor by urine cytology in cases of prostatic hypertrophy

Routine urine cytology has been performed for 809 male patients presenting with symptoms due to prostatic hypertrophy. In 6.42% of the cases, bladder tumor was revealed incidentally diagnosed by urine cytology. Cystoscopy and bladder biopsies were performed to confirm malignancy. The age of these patients ranged from 48–84 years (mean 65.2) and they complained mainly of irritative bladder symptoms. It is therefore strongly indicated that all patients with prostatic disease should have routine cytological examination of urine sediments. Diagn Cytopathol 1996;15:409–411
