[Urethroplasty and separation of the corpora cavernosa for hypospadias repair].

Hypospadias is a frequent malformation and its treatment is not devoid of complications, particularly fistulas. The authors describe the department's surgical technique (modified Duplay technique). Urethroplasty is no longer performed by simple approximation of the urethral plate without dissection. The inferior surface of corpora cavernosa is exposed as far as the lateral border and as far as the summit in the glans, allowing tension-free suture of urethral tissues with a lengthening effect of this intermediate plane. This completes correction of chordee and especially "bucket-handle" glans and protects the reconstructed urethra and proximal urethra. The risk of fistula is therefore reduced (2 cases out of 51). This technical modification can be used to treat all forms of distal hypospadias (glanular, glanulo-preputial, and anterior penile). It has also been used for several cases of more severe hypospadias. These good results must be confirmed in a larger series of patients.
