OBJECTIVES: To compare the results of two different techniques of dorsal onlay lingual mucosal graft (LMG) urethroplasty for anterior urethral strictures. METHODS: Thirty patients underwent dorsal onlay LMG urethroplasty by Barbagli's technique (group I) and 25 through a ventral sagittal urethrotomy approach (group II). All of the patients were followed up with a pericatheter urethrography at 3 weeks, retrograde urethrography with micturating cystourethrography and uroflowmetry at 3, 6 and 12 months. RESULTS: Mean follow up was 22 months and 13 months in group I and II, respectively. The mean peak flow rate increased from 4.2 mL/s preoperatively to 35.5, 25.06 and 25 mL/s at 3, 6, and 12 months, respectively, in group I and from 7.8 mL/s to 34.2, 28.4 and 26.2 mL/s at 3, 6 and 12 months, respectively, in group II. Five patients in group I and two patients in group II had an anastomotic stricture at 12 months. Meatal narrowing was seen in five patients in group I and three patients in group II. The overall success rate was 83.4% and 76.6% in group I and 90% and 80% in group II at 6 and 12 months, respectively. One patient had chordee in group I and no patient had chordee in group II. There was a shorter operative time and less blood loss in group II. CONCLUSIONS: Dorsal onlay LMG urethroplasty through a ventral sagittal approach is better than the Barbagli's technique in terms of results and complications.
