    Author: Kurokawa I, Nomura Y, Nakagawa C, Okada Y, Fuji K, Yoshimura Y.
    Journal: Int J Urol; 2023 Jul; 30(7):586-591. PubMed ID: 36946367.
    Abstract:
    OBJECTIVES: We aimed to report the background of patients with vesicovaginal fistulas (VVFs) at our center, which has treated a relatively large number of such patients in Japan, as well as the ingenuity and outcomes of vesicovaginal fistula closure (VVFC). We also investigated the causes of VVFs. METHODS: A retrospective review was performed for 28 patients with VVFs treated at our center. Age, body mass index, etiology, site of fistula, and postoperative outcomes were investigated. RESULTS: Twenty-one (75%) fistulas occurred following hysterectomy. The overall success rate of VVFC was 85.7%, and the success rate limited to the first attempt was 89.5%. In 68% of cases, no bladder injury suspected as the cause of VVF was noticed during the surgery. Energy devices were used in all 12 patients for whom information on the type of device used for hysterectomy was confirmed. CONCLUSIONS: To our knowledge, this is the first report to evaluate a relatively large number of VVFCs in Japan. Although VVF is thought to be caused by bladder injury during hysterectomy, delayed thermal damage might also result in this pathology, even if there is no apparent intraoperative bladder injury.
