Corpus cavernosum abscess from a blind-ending urethra after urinary diversion surgery.

Corpus cavernosum abscesses are rarely seen in the clinical setting. We report the case of an early diagnosis of corpus cavernosum abscess due to a blind-ending urethra in a 60-year-old man without known risk factors and who was successfully treated by antibiotic therapy alone. In this case, the blind-ending urethra after urinary diversion surgery was considered a risk factor of the abscess formation. If the physician notes that the patient has fever of uncertain cause after urinary diversion surgery, he/she should examine the penis and perineum in consideration of the possibility of corpus cavernosum abscess.
