value of prostatic biopsy in the diagnosis of chronic prostatitis

ABSTRACT

68 patients diagnosed clinically as having chronic prostatitis were studied together with 12 controls who were not complaining of any symptoms that may suggest prostate. Twelve cases proved to have other pathological lesions not related to prostatitis [one had stone bladder, 5 had bladder neck obstruction and 6 had chronic cystitis]. In the remaining 56 patients sexual and urinary symptoms together with pain were the main complaints with the sexual symptoms being the commonest. 75% of our patients were married and more than73% of them were between the age of 30 and 45 years. Prostatic fluid examination showed the presence of more than 15 pus cells/HPF in 67.85% of the patients. Bacteriological culture was positive in only 22 patients [39.3%]. It revealed Staph aureus in 21.4%; B.coli in 14.3% and other forms in 3.57% of the total number of patients.Histopathological findings showed no evidence of inflammation in 76.8% of cases, bacterial infection in 16.1% and the remaining 7.1% had bilharzial infection. Transperineal prostatic biopsy is a safe and relatively accurate method of diagnosis but it should not be done routinely.It should be reserved for of cases persistent symptoms and negative growth, for suspected granulomatous or allergic prostatitis of and for cases with palpable nodule or on suspicion of malignancy
