To evaluate our patients who were treated with ventral buccal mucosa onlay grafts for open urethral stricture repair with a follow-up exceeding 5 years. Buccal mucosa onlay is widely used for urethral reconstruction; however, the long-term outcome of these patients remains unclear.


During the past 10 years, 67 patients underwent ventral buccal mucosa onlay graft surgery for urethral stricture repair. Of these, 32 were followed up for longer than 5 years (mean 6.9 years) for the occurrence and timing of any postoperative complications. All patients had undergone prior internal urethrotomy (mean 2.9 procedures), and the average length of the stricture was 4.3 cm (range 3 to 17).


The overall complication rate was 25% (8 of 32). We observed one fistula, one graft infection/necrosis, two lower lip scars with transient impairment of lip motility, and four recurrent strictures (at the proximal anastomosis), all of which were treated successfully with internal urethrotomy. All but one recurrent stricture occurred during the first 12 postoperative months.


Ventral buccal mucosa onlay grafting for urethral stricture repair provides stable long-term results with complications occurring primarily during the first 12 postoperative months.
