[A CASE OF BULBAR URETHRAL STRICTURE SUCCESSFULLY TREATED WITH DORSOLATERAL ONLAY URETHROPLASTY USING A BUCCAL MUCOSA GRAFT].

A 19-year-old man was referred to our department because of repeated urinary retention. Urethroscopy and retrograde urethrography revealed a stricture 25 mm long at the mid to distal bulbar urethra. As he does not have any histories of trauma, urological procedure, sexually transmitted disease and lichen sclerosus, he was diagnosed as having an idiopathic bulbar urethral stricture. Therefore, we performed substitutional urethroplasty with buccal mucosa placed on the dorsolateral surface (one-sided dorsolateral onlay). The maximum flow rate by uroflowmetry and the International Prostate Symptom Score remarkably improved. His subjective symptom of ejaculatory function was also improved, while the erectile function was not affected. This is the first reported case of bulbar urethral stricture successfully treated with one-sided dorsolateral onlay urethroplasty using a buccal mucosa graft in our country.
