保存的加療で治癒した巨大前立腺膿瘍

A case of huge prostatic abscess resolved by antibiotic agents with cystostomy.

症例は58歳，男性。発熱，会陰部痛を主訴に当科受診。直腸指診で前立腺の波動を触知し，CTで前立腺に囊胞性病変を認めたため，前立腺膿瘍と診断した。抗菌剤投与および経皮的膀胱瘻造設術を施行した。その後直ちに解熱し，画像上も膿瘍は縮小し，外科的治療を要せず軽快した。

A 58-year-old male presented with high fever and perineal pain. Digital rectal examination revealed fluctuation of the prostate and CT showed multiple cystic lesions in the enlarged prostate. Based on the diagnosis of prostatic abscess, we treated him with antibiotic administration and placement of suprapubic cystostomy catether. After those procedures, the abscess diminished in size, and his general condition ameliorated. We experienced a rather rare case of large prostatic abscess successfully treated without surgical drainage.
