RESUMEN
PURPOSE: Hypospadias surgery is challenging. Numerous techniques have been described with variable complication rates. The main objectives of our study were to evaluate the urethroplasty complication rate of primary hypospadias repair and to identify risk factors for complications. METHODS: We retrospectively evaluated the outcomes of all patients who underwent primary hypospadias repair in our department between January 2012 and December 2020. Demographic, anatomical, operative, and postoperative data were reported. Univariate and multivariate logistic regression analyses were performed to identify variables associated with complications. Statistical significance was set at p < 0.05. RESULTS: Of 292 patients, 203 (69.5%) had distal hypospadias, 63 (21.6%) had mid-penile hypospadias, and 26 (8.9%) had proximal hypospadias. The mean age at the time of surgery was 22.8 months. Seventy-eight patients (26.7%) had urethroplasty complications. The rate of complications was higher for proximal hypospadias (57.7%), onlay island flap (44.4%), and Koyanagi (75%) procedures. The mean follow-up duration was 29 months. Two predictors of complications were identified by multivariate analysis: catheterization duration and urethroplasty technique. The reoperation rate was 30.5%. CONCLUSION: Urethroplasty complications frequently occur after primary hypospadias repair. The complication rate was higher in proximal hypospadias. Catheterization duration and surgical technique were significant predictors of complications. A longer and more standardized follow-up is needed for a better assessment of hypospadias repair outcomes.
