慢性前列腺炎是泌尿外科最常见疾病,发生率约占泌尿外科患者的33％。该病明显影响患者生活质量,其程度与近期心肌梗死、不稳定心绞痛、活动性克隆病相似。随着对该病的深入研究,近年来对其病因、发病机制、诊断及治疗有了新的认识。1 病因 慢性细菌性前列腺炎约占慢性前列腺炎5％,通常由细菌经尿道逆行侵犯前列腺所致,偶因血行感染或急性前列腺炎转归而来,亦有继发于周围组织器官炎症或经淋巴播散所致。致病菌常见为表皮葡萄球菌、微球菌、金黄色葡萄球菌、克雷伯菌、肠杆菌属等。慢性细菌性前列腺炎临床特征为同一病原体引起的反复尿路感染,虽经抗生素治疗,该病原体依然存在于前列腺液中。原因可能与前列腺解剖因素有关即前列腺导管细长弯曲,开口处口径小,与尿道成直角或斜行向上进入 Chronic prostatitis is the most common urological disease, the incidence of urological surgery accounted for about 33% of patients. The disease significantly affects the quality of life of patients, its extent and recent myocardial infarction, unstable angina, active clonal disease similar. With the in-depth study of the disease, in recent years its etiology, pathogenesis, diagnosis and treatment have a new understanding. 1 Cause Chronic bacterial prostatitis accounts for about 5% of chronic prostatitis, usually caused by bacteria retrograde invasion of the prostate by urethra, occasionally due to blood infection or acute prostatitis come from, but also secondary to the surrounding tissue and organ inflammation or Lymph disseminated. Common pathogens Staphylococcus epidermidis, Micrococcus, Staphylococcus aureus, Klebsiella, Enterobacter and so on. Chronic bacterial prostatitis clinical features of the same pathogen caused by repeated urinary tract infections, although the antibiotic treatment, the pathogens still exist in the prostatic fluid. Causes may be related to prostate anatomy factors that slender curved prostate catheter, the small opening diameter, at right angles to the urethra or oblique upward into
