Objectives: To review the results of utilizing different grafts for substitution urethroplasty for anterior urethral stricture caused by balanitis xerotica obliterans (BXO). Methods: 153 patients who underwent substitution urethroplasty for anterior urethral strictures were included in this study. The stricture length varied from 3.8 to 16.4 cm (mean 10.2 cm). In 32% of the patients (49), local genital, penile (18), perineal (16) and scrotal (15) skin grafts were used. Over the 3 years our standard treatment policy has been to utilize a free mucosal graft from a non-genital area. Buccal mucosa was the most preferred, utilized in 74 (48.3%) patients and bladder mucosa in 12 (7.8%). Recently we have used lingual mucosal grafts in 18 (11.7%) patients for substitution urethroplasty. Results: The overall success rate for non-genital mucosal graft was 92.2%. The remaining 8 patients required more than one supplementary procedure postoperatively but none required a second urethroplasty. Of 49 patients who underwent substitution urethroplasty utilizing genital skin, the success rate was only 4%. 16.3% required one and 14.3% required multiple auxiliary procedures postoperatively. 34 patients (69.4%) required subsequent urethral reconstruction. Conclusions: A free graft urethroplasty using non-genital skin is recommended for anterior urethral stricture related to BXO.
