Comparison of perimeatal-based flap and tubularized incised plate urethroplasty combined with single- or double-layer dartos flap in distal hypospadias.
BACKGROUND
To determine whether the Mathieu technique with a single de-epithelized dartos flap, tabularized incised plate urethroplasty (TIPU) with a single de-epithelized dartos flap, or TIPU with double de-epithelized dartos flaps is the more appropriate treatment for distal hypospadias in terms of fistula rates.


METHODS
We present 2 surgeons' experiences with 95 cases of hypospadias repair using dartos flap neourethra covering. The study includes patients who underwent Mathieu and TIPU repair of hypospadias. They were divided into 3 groups: group 1 was treated with Mathieu urethroplasty with a single de-epithelized dartos flap; groups 2 and 3 were treated with a modified Snodgrass technique (group 2 with a single flap and group 3 with double flaps).


RESULTS
The results were quite successful, and indicated the superiority of the double de-epithelized dartos flaps (with no fistulas).


CONCLUSIONS
Double dartos flaps that are rotated around the penis are more effective than a single flap for prevention of urethrocutaneous fistulas.
