  ABSTRACT: In this manuscript the authors have studied the various causes of vesico-vaginal fistula (VVF) and described etiology, clinical characteristics, and surgical outcome of VVF patients managed at CCBRT. They show that out of 155 patients 104 had surgery for VVF, 25 for stress incontinence (SI), 7 for perineal tears, 6 for recto-vaginal fistula (RVF) and 5 for other reasons, such as urethral strictures and bladder stones. They found a rate of 37 (35.58% out of 104 patients) with definitely iatrogenic fistula and therefore support the observation also made by others that there is a shift in etiology of VVF.
