Incarceration of the Penis with an Urethral Fistula:A Case Report

An 80-year old man consulted us because of swollen glans and urinary incontinence. Physical examination revealed a rubber band tightly coiled around the coronal sulcus. After removal of the band, an urethral fistula of the ventral side was recognized. Conservative treatment resulted in good convalescence. Eighty-five cases of penile incarceration in Japan, including our case, are reviewed and discussed, with regard to motives, constricting objects, complications.
