Fifty-eight cases of chronic prostatitis were studied endoscopically and prostatic fluid culture was performed of sixteen cases. Needle biopsy of prostate was also done on twenty-five cases concomitantly and the following results were obtained:
1) Endoscopic appearance of the bladder neck was as follows,
1. Normal bladder neck, 13 cases (22. 4 per cent)
2. Elevated posterior urethra, 6 cases (10. 3 per cent)
3. Contracture of the neck, 8 cases (13. 8 per cent)
4. Diffuse, irregular swelling and narrowing of the neck, 11 cases (18, 9 per cent)
5. Reversed V-neck, 20 cases (34.4 per cent) The bladder neck was abnormal in 77.6 per cent of the cases
2) In 15 cases in which prostatic fluid culture was done, microorganisms were cultured in 13 cases. Staphylococcus epidermis was isolated in 6 cases and was most frequent etiologic organism of chronic prostatitis.
3) Result of biopsied tissue in 25 cases was as follows, no pathologic finding was present in 7 cases (28 per cent) and corpora amylacea in 6 cases (24 per cent) and inflammatory cells in 8 cases (32 per cent) and corpora amylacea with inflammatory cells in 4 cases (16 per cent).
4) Endoscopic examination, prostatic fluid culture and needle biopsy of prostate on chronic prostatitis, which was resistant to conventional therapy, are worthwhile and important procedures in establishing therapeutic criteria.
