Abstract:
PURPOSE: The purpose of this study was to investigate the risk factors for urethrocutaneous fistula development after hypospadias repair. MATERIALS AND METHODS: Between January 1990 and May 2010, 348 patients underwent hypospadias repair. This study included 294 patients who were followed up for more than 6 months. Potential risk factors for the development of fistula after operation included age, location of hypospadias, type of hypospadias repair, suture materials and methods, methods and duration of catheterization, combined congenital urologic disorders, timing of presentation and repair of fistula, and location of fistula. Data were analyzed retrospectively. Binary logistic regression analysis was used for univariate and multivariate analysis. RESULTS: Out of 294 patients, 63 patients (21.4%, 63/294) developed urethrocutaneous fistulas after hypospadias repair. In the univariate analysis, fistula formation was statistically related with type of hypospadias and type of hypospadias repair. In the multivariate analysis with stratification by hypospadias site, however, only the location of hypospadias was a significant independent risk factor in urethrocutaneous fistula development after hypospadias repair (p<0.001). CONCLUSIONS: Our results suggest that the risk of developing urethrocutaneous fistula after hypospadias repair is associated with the location of hypospadias (more proximal-type hypospadias). Type of hypospadias repair, suture materials, suture techniques, and number of other combined urologic disorders were not related to the development of urethrocutaneous fistulas.
