ABSTRACT

Objective To explore influences of the fistula's location on the procedure and outcome of a transvaginal vesicovaginal (VVF) repair.Methods The medical data of patients undertaken transvaginal VVF repairs in Peking University First Hospital between Janurary 2009 and Auguest 2016 were retrospectively collected,including age,past history,causes of the fistula,disease course,past treatment,outcomes of the cystoscopy and imaging test and surgical information.The follow-ups were performed.Patients who had incomplete clinical data and lost to follow-up were not included.The present study included 68 VVF subjects with the median age of 46 years (range24-64 years).The univariate analysis was performed to figure out potential risk factors for the VVF repair outcome.The duration and blood loss of VVF repairs were compared among the subjects with the fistulae located at bladder neck,trigone and supra-trigone region.Results There were 5,23 and 40 cases having VVFs located at bladder neck,trigone and supratrigone region respectively.The overall repair success rate was 88.2％ (60/68).According to results of the univariate analysis,subjects with more past repair times had significantly lower success rates.There were no significant differences in success rates of surgical repairs for VVFs located at bladder neck (80.0％,4/5),trigone (91.3％,21/23) and supra-trigone region (87.5％,35/40).And the location of VVFs had no significant association with the duration and blood loss during the VVF repair.Conclusions The location of VVFs had no influences on the procedure and outcomes of the transvaginal repairs.The VVF repair approach may not be determined based on the fistula's location alone.
