ABSTRACT
Prostatic abscess is seen infrequently. Furthermore small abscess or microabscess accompanied with BPH or chronic prostatitis is likely to be overlooked and very difficult to diagnose with history and physical examination due to obscurity of its clinical symptoms. We have experienced frequent pus discharge from resected area of prostate during transurethral resection in patients with BPH and/or chronic prostatitis. And through clinical observation of 32 patients with BPH and 7 patients with chronic prostatitis whom we had treated by transurethral resection of prostate following results were obtained. 1. Prostatic abscess was found in 26 cases of 39 patients with BPH and/or chronic prostatitis during transurethral resection of prostate. 2. Transvesical and transrectal ultrasonography of prostate may increase the chances to diagnose small abscess with sensitivity of 46%. 3. Urinary tract infection and concomitant prostatic calculi with lower urinary tract obstruction were important predisposing factors in formation of prostatic abscess. 4. Diabetes mellitus was accompanied in 5 cases of 26 patients of prostatic abscess. 5. Definite drainage with transurethral resection of the gland and the use of broad spectrum antibiotics brought good results.
