RESUMEN
OBJECTIVE: To explore an ideal urine drainage method and new urethral secretions of hypospadias repair. METHODS: The authors retrospectively analyzed 864 cases of hypospadias undergoing hypospadias repair and different post-operative urine drainages. The patients were divided into 5 groups based on the methods of urine drainage. RESULTS: The rates of such complications as cystospasm, infection of incisional wound and urinary fistula were as follows: modified method group: 2.86%, 3.33%, 1.90%; 3-tube method group: 10.77%, 11.54%, 8.46%; He's method group: 20.89%, 15.04%, 9.75%; traditional method group: 36.25%, 41.25%, 37.50%; 1-tube method group: 56.47%, 58.82%, 48.23%. The modified method was significantly better than all the other four methods (P < 0.05). CONCLUSION: As an ideal drainage method of urine and new urethral secretions of hypospadias repair, the modified method boosts the success ratio of hypospadias repair.
