V12-13: Two-sided dorsal plus ventral oral graft urethroplasty for long anterior urethral strictures
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.
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
