[Comparison and discussion of different surgical methods used to treat vesicovaginal fistulas].

Transvaginal repair has been the main surgery procedure for VVF, but it is limited by the location of fistula and the condition of vaginal. For patients not suitable for transvaginal repair, laparoscopic repair and open surgery are feasible. However both laparoscopic repair and open surgery are more invasive. Based on that, electrocoagulation becomes a better choice. In our research, patients with small and high location fistula treated by electrocoagulation got a higher cure rate and bear less surgical trauma. Electrocoagulation used in the treatment of VVF showed advantages of less trauma, less bleeding and better satisfaction. Fistulas with low location were more suitable for transvaginal repair. Complex VVF, especially with narrow ureteral open and ureteral fistulas, were more suitable for open and laparoscopic repair. As for single and small fistula, the electrocoagulation can be the first choice.
