Forty patients with long segment (more than 1.5 cm) anterior urethral stricture who underwent substitution urethroplasty using dorsolateral onlay BMG urethroplasty were evaluated with detailed history, physical examination, ultrasonography of KUB with PVRU, uroflowmetry, retrograde urethrography and voiding cystourethrography, sono-urethrograms and cystoscopy. After treatment with dorsolateral onlay BMG urethroplasty, they were followed-up with uroflowmetry at 3 monthly interval for one year and RGU and/or urethroscopy if indicated. Success was defined as normal voiding pattern without any intervention post-operatively.
