Rectourethral Fistulas Secondary to Prostate Cancer Treatment: Management and Outcomes from a Multi-Institutional Combined Experience

Purpose: Rectourethral fistula is a known complication of prostate cancer treatment. Reports in the literature on rectourethral fistula repair technique and outcomes are limited to single institution series. We examined the variations in technique and outcomes of rectourethral fistula repair in a multi-institutional setting.Materials and Methods: We retrospectively identified patients who underwent rectourethral fistula repair after prostate cancer treatment at 1 of 4 large volume reconstructive urology centers, including University of California-San Francisco, University College London Hospitals, Lahey Clinic and Devine-Jordan Center for Reconstructive Surgery, in a 15-year period. We examined the types of prostate cancer treatment, technical aspects of rectourethral fistula repair and outcomes.Results: After prostate cancer treatment 201 patients underwent rectourethral fistula repair. The fistula developed in 97 men (48.2%) after radical prostatectomy alone and in 104 (51.8%) who received a form of ene...
