[Repair of urethrocutaneous fistula with double skin flap. Report of 32 cases]. / Réparation des fistules uréthrocutanées par double lambeau cutané. A propos de 32 cas.

ABSTRACT

OBJECTIVES: Urethro-cutaneous fistula constitutes the main complication of urethroplasty for hypospadias. The frequency of this complication ranges from 12 to 90%. The multiplicity of fistula closure techniques, reflects the difficulty involved in repairing these lesions. The authors evaluated fistula repair by a double pedicle skin flap according to the Wise technique. MATERIAL AND METHODS: 32 patients were treated 18 had already undergone 34 attempted repairs of urethro-cutaneous fistulas complicating urethroplasties (9 Mathieu, 17 Duplay and 6 Leveuf) for anterior penile (9), middle penile (14) and penoscrotal hypospadias (9). In 14 cases, the Wise technique was the first procedure used to repair the fistula. RESULTS: The authors obtained 29 successes. The 3 failures concerned fistulas after Duplay urethroplasties to correct penoscrotal hypospadias. The overall success rate of this technique in our series (90%) was therefore close to that reported by Wise (5 out of 6 successes), who described this technique in 1977. CONCLUSION: The Wise technique is a good technique for repair of large, recurrent urethro-cutaneous fistulas after several attempts of repair.
