Use of buccal mucosa patch graft for recurrent large urethrocutaneous fistula after hypospadias repair.
BACKGROUND
To assess the effectiveness of buccal mucosa patch graft in the treatment of recurrent large urethrocutaneous fistula after hypospadias repair.


METHODS
A free graft of buccal mucosa was used for closure in 7 boys (mean age 4.8 years) with large (>4 mm) urethocutaneous fistula. Four fistulas were in the midshaft, 2 of them penoscrotal and 1 coronal type. All patients had undergone at least two previous unsuccessful fistula repairs, and 3 of them had undergone three attempts for closure. Fistula repairs were similar in all cases.


RESULTS
The repair was successful in 6 out of 7 cases, and in these cases the urinary stream was good after the removal of the catheter. The unsuccessful case was the coronal one.


CONCLUSIONS
Based on our experience it seems that in cases with recurrent large fistula after hypospadias reconstruction, the use of buccal mucosa patch graft for closure is a good treatment choice.
