Bacteriological Study on Chronic Prostatitis

Lee, Chul Ho; Yun, Nung Su

Abstract

A bacteriological study was made on 21 cases of the chronic prostatitis suspected by subjective symptoms, microscopic findings of urine, rectal findings of prostate and microscopic findings of prostatic secretion during the period from June to October 1980, and clinical observation was also performed. The results were summarized as follows; 1. The distribution of age showed the highest incidence in 20 to 39 years (16 cases: 76.2%). 2. 13 cases (61.9%) of patients had previously experienced acute or chronic urethritis. 3. Major subjective symptoms consisted of pollakisuria (12 cases: 57.1%), perineal discomfort and urethral discomfort in order of frequency. 4. On rectal palpation of prostate, 18 cases (85.7%) were abnormal in consistency. Most of the prostate were normal in size, but 9 cases enlarged and 1 case was small. 5. Majority of the cases (18 cases: 85.7%) were normal in microscopic examination of urine. 6. In microscopic findings of prostatic secretion, 17 cases (81.0%) showed W.B.C. more than 10/H.P.F. 7. In 21 cases in which urine and prostatic secretion culture were done, microorganisms were cultured in 9 cases (42.9%) and no growth was noted in 12 cases (57.1%). There were 3 cases of mixed infection. The isolated microorganisms revealed 6 cases of Staphylococcus aureus, 3 cases of E. coli, 1 case of Staphylococcus epidermidis, 1 case of Pseudomonas fluoresces and 1 case of Alcaligenes. 8. The mean colony counts were as follows. VB1: 881+/-583 colonies/ml VB2: 123+/-112 colonies/ml EPS: 57,778+/-28,299 colonies/ml VB3: 5,389+/-4,745 colonies/ml There was more predominant growth in EPS and VB3 than VB1 and VB2. 9. Microscopic findings of biopsied prostatic tissue showed infiltration of chronic inflammatory cells in all 4 cases. The results of bacterial culture of prostatic tissue were negative in 2 cases, Staphylococcus aureus in 1 case and E. coli in 1 case. The isolated microorganisms were identical to prostatic secretion cultures. 10. The pH of prostatic secretions were 14 cases (66.7%) in 7.7 to 8.0 and 4 cases (19.0%) in over 8.0. There was no significant difference in pH of prostatic secretions between prostatic secretion culture positive group and culture negative group.
