title: Oral mucosal grafts urethroplasty for the treatment of long segmented anterior urethral strictures.
abstract: OBJECTIVE
  To evaluate the efficacy and safety of using oral mucosal grafts for urethroplasty in the treatment of complex segmented urethral strictures.
  
  
  METHODS
  Between January 2002 and January 2008, 25 cases of long or multi-segmented urethral strictures (10-18 cm, mean 11.72) were treated using combined two oral mucosal graft urethroplasty. Of the 25 patients, combined double buccal mucosal graft (BMG) urethroplasty was performed in nine patients, double lingual mucosal graft (LMG) urethroplasty in seven patients and combined lingual and buccal mucosal graft urethroplasty in nine patients.
  
  
  RESULTS
  Follow-up was obtained for 6-72 months (mean 26.83) post-operatively. Urethrocutaneous fistulas developed in two patients. Urethral strictures developed in one patient undergoing BMG urethroplasty; the patient underwent five urethral dilations, after which he voided well with a urinary peak flow of 26.4 ml/s. Meatal stenosis developed in one patient undergoing LMG and a second operation was required, after which the patient voided well (urinary peak flow of 28.7 ml/s). The other patients voided well and urinary peak flow rates ranged from 16.8 to 49.2 ml/s (mean 28.65 ml/s).
  
  
  CONCLUSIONS
  Combined two oral mucosal grafts substitution urethroplasty is an effective technique for the treatment of long, segmented urethral strictures.
