Buccal mucosal graft interposition in the treatment of recurrent vesicovaginal fistula: A report on two cases.

OBJECTIVE: To present the use of autologous buccal mucosa graft (BMG) in the treatment of recurrent vesicovaginal fistula (VVF). CASE REPORTS: In 2011, two women, aged 45 years and 56 years, were admitted due to recurrent VVF. Both women had previously undergone abdominal hysterectomies for benign conditions and, subsequently, vaginal VVF repair due to vaginal urine leakage. On admission, the younger woman had a round fistula, with a diameter of 1.5 cm, located on the left side, supratrigonally; the other woman had an ellipsoidal fistula measuring 2.5 cm × 1.5 cm, located medially and supratrigonally. Both women underwent suturing of the VVF with the interposition of BMG. After the last treatment, both women were cured. CONCLUSION: Treatment of recurrent VVF with the interposition of BMG is a good alternative to the use of other tissue grafts. Larger series are needed to confirm the advantages of this method.
