難治性非細菌性前立腺炎およびプロスタトディニアに対する経直腸的超音波治療

Abstract

前立腺炎と診断され2ヵ月以上の経過を有する非細菌性前立腺炎およびプロスタトディニア25例を対象に超音波治療器による治療効果を検討した。Symptom scoresのみを用いて治療効果判定を行ったがscoresが70%以上の改善を著効, 40～69%の改善を有効, 10～39%の改善をやや有効, 10%未満ないし悪化を無効, 治療前のscoresが4以下の場合を判定不能とすると, 判定不能の7例を除く18例における治療効果判定は有効以上50.0%, やや有効以上72.2%となり, 副作用はまったくなく, 超音波治療器による治療は投薬が無効な非細菌性前立腺炎およびプロスタトディニアの症例に試みて良い治療とおもわれたが, 1回約5分, 1クール8回の施行は外来診察中の医師にとって時間的に決して容易ではなく, 患者自身が施行できるような器械の改良が望まれる

A total of 25 patients with nonbacterial prostatitis and prostatodynia which were resistant to conventional drug therapy underwent 5 minutes course of transrectal ultrasonic therapy in association with application of 1% hydrocortisone acetate cream to the anterior rectal wall for consecutive 8 days. The efficacy of the treatment was evaluated only by comparison of symptom scores for subjective symptoms obtained before and after treatment. Excellent results, which were defined as more than 70% reduction of symptom scores after treatment, were obtained in 5 (27.8%) among 18 evaluable cases in which symptom scores before treatment were more than 4, good (40-69% reduction of scores) in 4 (22.2%), fair (10-39% reduction of scores) in 4 (22.2%) and poor (less than 10% reduction of scores) in 5 (27.8%). Because of good clinical efficacy and the absence of complication, transrectal ultrasonic therapy combined with hydrocortisone acetate cream application was thought to be useful for the treatment of nonbacterial prostatitis and prostatodynia cases which responded poorly to the conventional therapy.
