Ultrasound-guided puncture and drainage for penile abscess: Case report and review of the literature

Abstract

A subcutaneous abscess of the penis is a rare condition. It can be idiopathic or have an underlying cause, such as intracavernous injection therapy, foreign body, dilated perineal abscess, abnormal erection, or trauma. Clinical signs are mainly swelling in the penis, penile pain, and swelling. Conventional treatment is primarily surgical incision and drainage, followed by systemic antibiotic therapy. In recent years, with the development of medical technology, minimally invasive interventions and less invasive techniques, such as ultrasound-guided aspiration, are being developed. This article aims to report a case of ultrasound-guided successful diagnosis and treatment of an aseptic idiopathic subcutaneous abscess at the root of the penis and to review the literature on penile abscesses. The patient, a 61-year-old male, underwent ultrasound-guided puncture and drainage using a coaxial aspiration/flushing technique in combination with antibiotics to treat this rare urinary tract condition. The patient recovered well postoperatively and was discharged 3 days later. At a 2-week postoperative follow-up, an ultrasound showed a marked reduction in the penile abscess mass.
