RESUMO
An 85 year-old man was referred to our hospital because of a relapse of abscess after open surgical drainage of the right scrotum. Computed tomography (CT) showed fluid accumulation in the right scrotum and around the membranous urethra. The abscess was controlled by an open surgical drainage of the right scrotum, CT guided percutaneous drainage of the periurethral abscess and administration of antibiotics. However, the scrotal abscess recurred after 4 weeks. CT showed an enlarged abscess, and retrograde urethrography showed an urethral diverticulum extending into the scrotum associated with a scrotal abscess. Endoscopic urethral diverticulum unroofing and cautery were performed. The urinary catheter was removed 2 days after the operation. The abscess has been resolved without recurrence.
