INTRODUCTION

Substitution urethroplasty provides good functional results in bulbar and penile urethral strictures. However, treatment of long(extending from external meatus to bulbar urethra) and tight strictures remains a challenge. One-sided (dorsal or ventral) substitution urethroplasty may not be sufficient in long strictures with a narrow urethral plate. In recent years, we have opted to use two-sided oral mucosa graft (OMG) in such cases. We describe our technique of two-sided OMG urethroplasty in long and tight strictures.

METHODS

Among the 83 men that underwent anterior urethroplasty in our clinic between 2010 and 2015, 23 (27.7%) had long(>80mm) or multiple strictures. Clinical evaluation included assessment of subjective symptoms with the AUA symptom score and patient-reported outcome measure for urethral stricture (USS-PROM), uroflowmetry, and combined retrograde urethrography/voiding cystourethrography. We performed two-sided urethral augmentation in patients with a tight stricture (ie. urethral caliber
