[Tunica vaginalis of testis and spermatic fascia: a good alternative for the repair of urethral fistula resulting from hypospadias operation].
OBJECTIVE
To evaluate the methods of repairing urethral fistula resulting from hypospadias operation.


METHODS
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.


RESULTS
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).


CONCLUSIONS
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.
