Rectourethral fistula and massive rectal bleeding from iodine-125 prostate brachytherapy: a case report

Abstract

Iodine-125 brachytherapy is an effective well-tolerated treatment for localized prostate cancer. Gastrointestinal complications of brachytherapy (minor rectal bleeding or tenesmus) are uncommon. Rectal ulceration or rectourethral fistulas after prostate brachytherapy are rare. We present a case of massive refractory rectal bleeding and rectourethral fistula, a complication of prostate brachytherapy never before reported. As a result of the patient's life-threatening symptoms aggressive surgical therapy was necessary.
