Use of electrocoagulation in the treatment of vesicovaginal fistulas.

The role of electrocoagulation for the treatment of vesicovaginal fistulas has not been clearly defined. To determine the use of this therapeutic modality, 15 cases of fistulas treated with electrocoagulation were retrospectively reviewed. Fulguration represented the primary treatment in 12 patients and the secondary treatment in 3 after an initial attempt at open surgical closure failed. In all instances fistula size was estimated to be 3.5 mm. or less. A Bugbee electrode, which was inserted into the fistula either cystoscopically or vaginally, was used to destroy the epithelial lining of the fistula tract. Following the procedure the bladder was decompressed with a large indwelling Foley catheter for at least 2 weeks. Fulguration was successful as the sole treatment modality in 9 of 12 patients (75%) and as an alternative intervention after failure of an open surgical repair in 2 of 3 (66%). Therefore, 11 of the 15 women (73%) had complete resolution of the fistulas with this technique. We conclude that fulguration is usually effective in managing patients with vesicovaginal fistulas a few millimeters in size or less. This technique should be used as an initial treatment for appropriately selected patients and in women with small residual fistulas after open surgical failure.
