[One-stage reconstruction of distal urethra with free graft of tublar oral mucosa ].

Objective To investigate the therapeuctic effect of one-stage reconstruction of distal urethra with free graft of tublar oral mucosa. Methods Two strips of oral mucosa graft( 0.4—0.6 cm in width), were harvested and sutured around an oiled silk roll to form mucosa tube. The mucosa tube was used to reconstruct distal urethra. Postoperative pressure dressing and earlier urination were recommended. Results From May 2007 to October 2015, 16 cases with distal urethra defect or stenosis were treated with this method. The urethra defect was 2—4 cm in length. Urethral fistula happened in 3 patients. All the other 13 cases healed primarily. 10 cases were followed up for 1—5 years by telephone with normal function. Conclusions One-stage reconstruction with free graft of bulbar oral mucosa is suitable and reliable for distal urethra defect less than 4 cm in length.
