Objective: To discuss the diagnosis and treatment of non-specific granulomatous prostatitis (NSGP).
Methods: Thirty-two cases of NSGP were diagnosed by puncture biopsy under transrectal ultrasound (TRUS) and treated with antibiotics and other medicines from September, 2000 to May, 2006.
Results: Pathomorphologically, NSGP was basically characterized by granuloma with vessels or grand alveoli in the center. The mean follow-up was 24 months. Urination irritation and obstruction were improved. Q(max) was increased to 15.0-24.0 ml/s, and in 3 cases of urinary retention, to 12.0, 14.5 and 16.5 ml/s, respectively. Digital rectal examination (DRE) indicated a reduced size and softened texture of the prostate induration. PSA was decreased to 1.3-11.5 microg/L. Four cases experienced relapse but were cured after retreated. No prostate cancer was observed.
Conclusion: NSGP can be definitely diagnosed by puncture biopsy under TRUS and effectively relieved by antibiotics with the alpha-receptor blocker. In case of serious obstruction complicated by urinary retention, transurethral electrotomy can be considered.
