慢性前立腺炎と前立腺炎様症候群の臨床的研究 第1報: 臨床統計的観察

Abstract

慢性前立腺炎およびその類似疾患605症例を対象に臨床統計的観察を行った.1)発症頻度は総外来患者の4.34%, 男子患者の7.54%に相当した.年齢は平均は38.1歳で青壮年代に多い.月別頻度で10～12月, 6月に有意に受診患者が多い.2)病型分類は慢性前立腺炎が48.1%(細菌性5.3%・非細菌性42.8%), 前立腺炎様症候群が51.9%であり, 頻度(男子患者比)は慢性前立腺炎が3.63%(細菌性0.40%・非細菌性3.23%), 前立腺炎様症候群が3.91%である.3)慢性前立腺炎と前立腺炎様症候群での臨床像の統計学的比較では, 症状・職業・誘因には差はないが, 細菌培養・前立腺触診所見・治療歴(罹病期間, 受診施設数)・既往症・合併症には病型間に有意差があった.4)以上より, 2病型を病態の異なる疾患として分類・診断することが重要である

We clinically evaluated 605 cases of chronic prostatis and other resembling disorders. The incidence was 4.34% of all out-patients (7.54% of male patients). The average age was 38.1 years, and many were adolescents. A greater number of out-patients were seen in October, November, and December (p less than 0.01) and June (p less than 0.05). The type of disease was chronic prostatitis in 48.1% (bacterial in 5.3%, non-bacterial in 42.8%) and prostatitis-like syndrome in 51.9%. The incidence among male patients was 3.63% for chronic prostatitis (bacterial in 0.40%, non-bacterial in 3.23%), and 3.91% for prostatitis-like syndrome. In the case of chronic prostatis, the abnormal finding rate (p less than 0.01), tenderness (p less than 0.01), induration (p less than 0.05) on prostatic palpation, non-pretreated rate (p less than 0.01), urological past history (p less than 0.05) except prostatitis and urological complications (p less than 0.01) were significantly higher. On the other hand, the negative rate on urine culture (p less than 0.01), no abnormal findings on palpation (p less than 0.01), discomfort (p less than 0.01), discomfort with tenderness (p less than 0.01) and past prostatitis episodes (p less than 0.01) were seen significantly more in the case of prostatitis-like syndrome. In conclusion, chronic prostatitis with inflammatory change on prostate and prostatitis-like syndrome without inflammation have similar clinical features, but should be diagnosed as totally different types of disease.
