Clinical Study of Single Stage Dorsolateral Onlay Buccal Mucosal Graft Urethroplasty in Long Segment Anterior Urethral Stricture

Abstract

1.1. Objectives: To evaluate the results of dorsolateral onlay buccal mucosal graft (BMG) urethroplasty in various types of long segment anterior urethral stricture. 1.2. Materials and Methods: This is a prospective study, conducted in the Department of Urology, Medical College, Kolkata and Burdwan Medical College, Burdwan from April 2017 to March 2021. 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. 1.3. Results: With nineteen of the forty cases (47.5%), lichen sclerosus formed the single most common etiology. Panurethral strictures were more common. Out of total 40 cases, 33 (82.5%) had successful outcome and 7 (17.5%) were failure. 1.4. Conclusion: We conclude that it is a simple, technically feasible, easily adoptable and finally successful procedure
