Objective: To review our experience with the modified York Mason (MYM) procedure in the treatment of rectourinary fistulas (RUFs) and to assess fecal continence using patient-reported measures. Materials and Methods: A retrospective review was performed of patients who underwent MYM repair of nonradiated RUF with gluteal free fat graft from 2008 to 2016 at a single institution. Success was defined as resolution of the fistula without need for further surgery. The Cleveland Clinic-Florida Wexner Fecal Incontinence Score (CCFFIS) and the Patient Global Impression of Improvement (PGI-I) surveys were administered by phone. Results: Of 17 patients who underwent MYM repair with a mean age of 61.8 years old, the most common fistula etiologies were prostatectomy in 11 patients (65%), cryoablation in 2 patients (12%), and transanal tumor excision (12%). Three patients (18%) failed prior perineal repairs. The mean fistula size was 10.1 mm (range 2-25), the median operative time was 231 minutes (range 151-365), and the median length of stay was 2.0 days (range 1-13). At the median follow-up of 39.4 months, 16 of the 17 patients (94%) had successful primary closures. The condition of the 10 patients who responded to the phone survey was “much better” (median PGI-I score 2), with 89.5% mean improvement. The mean CCFFIS was 1.4 (range 0-5) on a scale of 0 (total continence) to 20 (complete incontinence). Two patients (20%) reported rare (<1 per month) fecal incontinence, and 2/10 (20%) reported frequent flatal incontinence, but none reported significant lifestyle change or sought further treatment for bowel symptoms. Conclusion: The MYM technique has a high success rate in the treatment of nonradiated RUF with negligible impact on fecal continence.
