ABSTRACT
Objective To investigate the efficacy and safety of using combined lingual mucosa and buccal mucosa onlay grafts or foreskin flap urethroptasty for the treatment of long or multi-seg-ment urethral strictures. Methods Seven patients with long and 4 cases with multi segment urethral strictures(range 10 to 15 cm,mean 12)underwent substitution urethroplasty using combined lingual mucosa and buccal mucosa onlay grafts or foreskin flap urethroplasty.The patients'age ranged 24 to 56,mean 32 and the course of disease was from 6 to 96 months.Of the 11 patients 7 underwent com-bined lingual mucosa and buccal mucosa grafts urethroptasty,4 patients underwent combined lingual mucosa graft and foreskin flap Urethroplasty. Results The patients were followed up 5-1 2(mean 10)months postoperatively. Meatal stenosis developed 3 months postoperatively in 1 patient who un-derwent combined lingual mucosa and foreskin flap urethroplasty.The patient could void well after re-operation.The other patients could void well and the peak flow rate ranged from 2 1 to 3 6 ml/s(mean 26.8 ml/s). Conclusions Combined lingual mucosa and buccal mucosa onlay grafts or foreskin flap substitution urethroplasty may have the advantage of easier harvest,less trauma.It could be a good U- rethral substitution technique for the treatment of long or multi-segment urethral stricture.
