Dorsal onlay lingual mucosal graft urethroplasty: Comparison of two techniques.
OBJECTIVE
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.
