Abstract:
Radiation therapy is a well-recognized treatment for unfavourable risk localized prostate cancer. Radiation induced recto-urethral fistulae are known rare complications particularly from brachytherapy. We report a case of a recto-urethral fistula 7 years post-external beam radiation and I-125 brachytherapy, which was complicated by a severe polymicrobial soft tissue infection. This infection required penectomy and pelvic exenteration with diverting colostomy, Indiana pouch urinary diversion and gracilis myo-cutaneuos flap closure of the perineum.
