気腫性膀胱炎加療後の膀胱内巨大壊死組織に対してTURが有効だった1例

Abstract

Emphysematous cystitis is a relatively rare form of urinary tract infection. A 72-year-old man with diabetes mellitus and long-term indwelling urethral catheterization was diagnosed with emphysematous cystitis. The clinical findings were resolved by conservatively managing the patient with antibiotics. However, cystoscopy subsequently revealed a yellowish-white soft tissue mass in the bladder, which was unlikely to be a bladder tumor. The mass could not be removed easily and frequently caused urinary catheter obstruction. We successfully removed this mass by performing transurethral resection twice. Through histopathological examination, the mass was identified as necrotic tissue comprising bacteria, fibrin, and suspected bladder mucosa.
