[Duckett's+ simple surface or double surface? Comparison of 2 urethroplasty procedures. Report of 91 hypospadias]

Abstract

The results and complications of the treatment of hypospadias were studied in relation to the two pedicle foreskin mucosal flap techniques described successively by Duckett, "single surface" and "double surface". 91 urethroplasties were performed: 58 "single surface" and 33 "double surface" Duckett urethroplasties. The children were operated between the ages of 18 months and 16 years with a mean age of 4 years. 75% of children had a good result on long-term follow-up. In the case of major complications, essentially fistula, distal necrosis àf the urethra or stricture, a single reoperation increased the percentage of good results to almost 98% for the entire series. However, when the two procedures were compared, a good result was obtained immediately in 81% of cases for the "single surface" operation versus 66% for the "double surface" operation. The fistula rate was 27.2% with the "double surface" flap versus 13.7% with the "single surface" flap and the distal stricture rate was 15.1% with the "double surface" flap versus 3.4% with the "single surface" flap. In the light of these results, Duckett's "double surface" procedure has been abandoned in favour of the "single surface" flap.
