(Objective) We evaluated the efficacy and outcome of one-stage oral mucosa graft urethroplasty, which is currently the procedure of choice for treating lengthy and complicated urethral strictures not amenable to excision and primary end-to-end anastomosis. (Patients and methods) Seven patients 33 to 74 years old (mean age = 53.7) underwent one-stage oral mucosa graft urethroplasty for a stricture in either the bulbar urethra (four patients), penile urethra (two patients), or pan-anterior urethra (one patient). Three of the strictures were due to trauma, one was due to inflammation, and one was due to a failed hypospadia repair. The other two were iatrogenic. All patients had previously undergone either internal urethrotomy or repeated urethral dilation. Three patients received a tube graft, three received a ventral onlay, and one received a dorsal onlay. A free graft of oral mucosa was harvested from the inside of each patient's left cheek, and if necessary to obtain a sufficient length, the harvest was extended to include mucosa from the lower lip and the right cheek. The graft lengths ranged from 2.5 to 12 cm (mean = 4.6 cm). A urethral catheter was left in place for 3 weeks postoperatively. (Results) While no severe complications at the donor site were observed during follow-up periods ranging from 3 to 55 months (mean = 14 months), two patients who had received a tube graft developed distal anastomotic ring strictures that were managed by internal urethrotomy. The other five required no postoperative urological procedure even though one who had received a ventral onlay developed a penoscrotal fistula (Conclusion) Oral mucosa is an ideal urethral graft and oral mucosa graft urethroplasty is an effective procedure for repairing complicated urethral strictures involving long portions of the urethra
