Value of urine cytology in screening patients with prostatitis syndromes.

We reviewed the results of urine cytology examination of 206 patients with a diagnosis of prostatitis syndromes in the period 1985-1991. The urine samples showed an incidence of 20.4% for slight to moderate atypia and 6.3% for severe atypia. In these patients, cystoscopy, bladder biopsies and intravenous urography were performed to exclude malignancies. In only 6 of the 13 patients with severe atypia of the urine cytology were malignancies found. In cases of malignancy, the ages of the patients ranged from 51 to 64 years (mean, 58.6), and they complained most frequently of irritative bladder symptoms. In these patients, urinalysis frequently showed leukocyturia, and in all the samples, erythrocyturia was found.
