Abstract:: PURPOSE: We evaluated stricture-free survival and functional outcomes of buccal mucosa graft urethroplasty in patients with urethral stricture disease after radiotherapy. MATERIALS AND METHODS: We reviewed our urethroplasty database for patients with a radiotherapy history who underwent buccal mucosa graft urethroplasty between January 2009 and October 2013. We reviewed patient charts and the institutional, standardized, nonvalidated questionnaires administered to each patient postoperatively. Study end points included 1) the success rate, 2) continence status, 3) erectile function and 4) patient satisfaction postoperatively. Success was defined as stricture-free survival. RESULTS: Of 38 men included in the study prostate cancer was the most common indication for radiotherapy in 35 (92.1%). External beam radiotherapy was performed in 24 cases (64.9%), brachytherapy was done in 8 (21.6%) and a combination of the 2 treatments was performed in 6 (13.5%). Strictures were in the bulbar/bulbomembranous urethra and had a median length of 3.0 cm (range 1.0 to 8.0). The overall success rate was 71.1% at a median followup of 26.5 months (range 1.0 to 50.0). Median time to stricture recurrence was 17.0 months (range 3.0 to 44.0). De novo urinary incontinence was observed in 4 patients (10.5%). Erectile function remained mostly unchanged compared to preoperative status. Study limitations include the small sample size and the lack of validated questionnaires. CONCLUSIONS: At short-term to mid-term followup the success rate of ventral onlay buccal mucosa graft urethroplasty in patients with radiotherapy history seems acceptable. However, patients must be counseled about the increased risk of urinary incontinence. Longer followup is warranted to address long-term outcomes.
