Abstract
BACKGROUND: Reconstruction of a urethral stricture poses a difficult surgical problem. Anastomotic repair remains the gold standard. Strictures longer than 2 cm may require substitution urethroplasty. This is a retrospective review of all patients who underwent urethral reconstruction with an autologous free buccal mucosa graft at a Regional hospital between 1998 and 2009. METHODS: Variables recorded included; demographics: patient gender/age; follow-up period. Urology: pre-operative diagnosis/aetiology; presenting complaint; previous urological surgery, pre-operative retrograde urethrogram, stricture length, graft size, operative time/blood loss, morbidity, complications. Maxillofacial: pre-/post-operative inter-incisal opening, patency of Stenson's parotid duct, ipsilateral parotid swelling, sensory nerve deficit. RESULTS: A total of eight male patients were included. Mean age was 33 years. Two patients had one-stage dorsal onlay urethroplasty, and the remaining six had a two-stage BMG urethroplasty. All patients underwent a urethrogram 20 days post-operatively, which demonstrated no leak, and a good caliber grafted urethra in all cases. A flexible cystoscopy scope was accommodated in all patients 8 weeks post-operatively. Mean follow-up was 42 months. At long-term follow-up, there was no evidence of stricture formation, and all patients were voiding well. There were no long-term intra-oral complications. CONCLUSION: This study suggests that anterior urethral strictures up to 6 cm in length may be predictably and safely managed with buccal mucosal urethroplasty. The buccal mucosa is easy to harvest, and can be used successfully in one- and two-stage grafting procedures. The rate of complications, from both a urological and maxillofacial perspective, in the group of patients studied was low.
