The pathological changes of acute prostatitis mainly polymorphonuclear leukocyte infiltration, destroy the prostate gland, Or catheter and prostate epithelial and mesenchymal its neighboring characteristics. By caused by bacterial infection. Because of its pathological changes of inflammation and the different types of distinction.
(1) card he prostatitis: infection by the prostate gland cavity to the excretion of the spread of congestion, edema, exudative increase. Endovascular epithelium with mild inflammatory cell infiltration,epithelial hyperplasia and scaling.
(2) follicular prostatitis: acinar have all epithelial shedding and invasion, as the development of inflammatory edema and congestive increased lumen stenosis occlusion, or small abscess formation of pseudo abscess. The entire gland softened, swelling flexible.
(3) substantive prostatitis: lesions further development, mesenchymal cells within eosinophilic infiltration extended to real, small abscess formation. Exfoliated epithelial necrosis, which are not easily distinguishable from glandular cavity. The spread of interstitial inflammation or the whole damn gland.
(4) prostatic abscess: real limitations for the development of inflammation abscess, or physical, it will infection and inflammation lymphatic blood infection caused prostate abscess. About 1 / 2 cases abscess will continue to increase, eventually urethra, perineum or rectum pierced.
