Objective To evaluate the effect of niti-alloy urethral stent on the prevention of urethrocutaneous fistula and urethral stricture in hypospadias repair. Methods From January 2001 to December 2004, niti-alloy urethral stents were applied to repair congenital hypospadias in 63 patients. Among 63 patients, 49( 19 cases of proximal hypospadias, 22 cases of penoscrotal hypospadias and 8 casesof perineoscrotal hypospadias) received one-stage surgical managements of urethral reconstruction, and 10 underwent postoperative fistular repairs and 4 received repeated urethral reconstruction because of urethral stricture after hypospadias repair. Results All patients gained healing by first intention without fistula or urethral stricture. The stents were left indwelling in the neourethra for 2 months to 3 months to prevent stricture. The longest indwelling period was about 1 year. No dysuria or other discomfort occurred during this period. Conclusion Niti-alloy urethral stent can effectively prevent the postoperative urethrocutaneous fistula and urethral stricture after hypospadias repair.
