経直腸的エコーによるいわゆる慢性前立腺炎の検討

TRANSRECTAL ULTRASONOGRAPHY OF PATIENTS WITH CHRONIC PROSTATITIS

　いわゆる慢性前立腺炎60症例に対して，治療中に施行した経直腸的エコー像を検討した．症状の椎移と慢性前立腺炎に特徴的とされる三項目の前立腺エコー像および新たに加えた前立腺周囲無エコー領域の有無から対象症例を四群に分けることができた．そのうち特に，無エコー領域のみを有する有症候群では前立腺周囲の欝血の存在が症状の消失をみない一因と推測された．

Transrectal ultrasonography was performed on 60 patients during the treatment of chronic prostatitis. These patients were divided into four groups by evaluating the change of subjective symptoms and, ultrasonic findings characteristic to chronic prostatitis including periprostatic echo-free zones (PEZ) which was assumed due to the dilatation of Santorini's plexus. Patients in group III who were reluctant to treatment had PEZ only, and were thought to have periprostatic congestion which was responsible for lasting symptoms.
