Sumario:INTRODUCTION: Osteomyelitis of the pubic symphysis is a rare condition often occurring in patients with radiation therapy-related urethral strictures after prostate cancer treatment. MATERIAL AND METHODS: We retrospectively reviewed patients who presented with osteomyelitis of the pubic symphysis from November 2016 to September 2021. We investigated the factors leading to urosymphyseal fistulas, clinical presentation, radiological assessment, treatments, and outcomes. RESULTS: A total 4 cases were collected. All patients underwent surgery and adjuvant or salvage radiotherapy for prostate cancer. Subsequently, they developed stricture of the vesicourethral anastomosis which was initially treated conservatively. Symptoms of pubic bone osteomyelitis included pain in the pubic area, fever, difficulty walking, and recurrent urinary tract infections. In all cases, computed tomography and magnetic resonance imaging showed a urinary fistula arising from the vesicourethral anastomosis with the involvement of the pubic bone, and severe osteomyelitis. Due to the failure of conservative treatment, debridement of the pubic bone with cystectomy and ileal conduit was performed in 3 patients. One patient refused surgery and bilateral percutaneous nephrostomies were placed. Patients regained their original performance status 1 to 6 months after surgery. CONCLUSIONS: General recommendations for the best diagnostic and therapeutic approach to osteomyelitis of the pubic symphysis due to urosymphyseal fistula still do not exist. Conservative treatment often fails and a surgical approach with definitive urinary diversion may be required.
