    Abstract:
    OBJECTIVE: To improve the success rate of one-stage urethral fistula repair by modifying the surgical procedures, suture material and application of urethral stent. METHODS: The clinical data of 56 cases of urethral fistula following correction of hypospadias were analyzed. The case group consisted of 38 cases with large fistula (over 3 mm in diameter) and 18 cases of small fistula (less than 3 mm). For the former cases, double skin flaps or pedicled skin flap from the scrotum were adopted for the repair; in the latter cases, transverse Y- or V-shaped skin flaps were used. Porous silica gel cannula was adopted for the stents. RESULT: A success rate of one-stage repair as high as 87.50% was achieved in these cases, with a rate for large fistula of 86.84%. CONCLUSION: Rich blood supply of the flaps, application of absorbable suture and urethral stent can improve the success rate of fistula repair.
