RESUMEN
<p><b>OBJECTIVE</b>To evaluate the methods of repairing urethral fistula resulting from hypospadias operation.</p><p><b>METHODS</b>We analyzed the clinical data of 46 cases of surgical repair of urethral fistula resulting from hypospadias operation. The patients ranged in age from 3 to 26 (mean 11.7) years. There were 52 fistulas in all, with the diameters of less than 5 mm, of which 25 were in the midshaft of the penis, 12 in the penoscrotum, and 9 in the scrotum. Of the 46 cases, 20 were repaired by continuous knock suture and 26 by tunica vaginalis of testis and spermatic fascia.</p><p><b>RESULTS</b>The one-stage success rate of continuous knock suture repair was 55% (11/20) and that of the combined use of continuous knock suture with tunica vaginalis of testis and spermatic fascia repair was 84.6% (22/26).</p><p><b>CONCLUSION</b>Based on continuous knock suture, the additional use of tunica vaginalis of testis and spermatic fascia yields a high success rate in repairing urethral fistula resulting from hypospadias operation.</p>
