Pedicled greater omentum graft: a new technique to repair recurrent urinary fistulae after kidney transplantation.

Urinary fistula is the most frequent urologic complication within the first month after kidney transplantation, which often leads to graft loss and mortality. Open surgery is the most popular approach for the treatment of these fistulae; however, it is associated with high failure rates. Here, we present a new technique of pedicled greater omentum graft to repair recurrent urinary fistulae after kidney transplantation. We used this technique in the repair of recurrent urinary fistulae in 13 post-kidney transplant patients. All operations were successful at the first attempt, and there was no fistula recurrence. Further, no complications associated with the technique have been observed during the follow-up (1-7 years). In conclusion, the use of pedicled greater omentum graft for the repair of recurrent urinary fistulae after kidney transplantation is both effective and safe.
