摘      要：Background Urethroplasty of complex urethral stricture is a difficult procedure, and there is no widely accepted standard approach described in the published literature. We evaluated the efficacy and safety of urethroplasty using lingual mucosa grafts （LMGs） for the repair of urethral strictures. Methods Between August 2006 and April 2009, 92 cases of urethral strictures （length ranging from 2.5 cm to 18 cm, mean 6.5 cm） were treated using LMGs. Of the 92 patients, 38 with long-segment urethral strictures （9-18 cm） underwent dual LMG or LMG combined with foreskin flap or buccal mucosal graft urethroplasty. Results Follow-up was obtained for 3-33 months （mean 17.2 months） postoperatively. Complications occurred in 8 patients, including urinary fistulas in 4 patients; recurrent strictures developed in 4 patients at 3-4 months post-operatively. The remaining patients voided well postoperatively, with peak flows between 14.3 ml/s and 54.6 ml/s （mean 28.4 ml/s）. Conclusions The tongue is an excellent source of graft material for the repair of anterior mucosal strictures. Dual LMG substitution urethroplasty can successfully treat longer, more complex urethral strictures.
