Novel Extravesical Versus Transvesical Technique for Abdominal Repair of Vesicovaginal Fistula
Objectives To compare the transvesical transabdominal repair of vesicovaginal fistula with novel extravesical
transabdominal repair with respect to operative time, blood loss, hospital stay, catheterization time, postoperative lower urinary tract symptoms, urodynamic changes, and recurrence rate.
Methods A prospective randomized controlled study of 94 consecutive female patients who underwent
transabdominal vesicovaginal fistula (VVF) repair from March 2013 to March 2018 in our center. The patients
had high vesicovaginal fistula that could not be operated on transvaginally: 47 cases were treated with extravesical transabdominal technique, and 47 cases were treated with transvesical transabdominal technique. The primary endpoint is the functional outcome regarding postoperative lower urinary tract symptoms (LUTS); secondary outcomes are early recovery and success rates. The follow-up period was 3 months for reporting and dealing with any complications.
Results There was no significant difference between the groups regarding demographic data. Extravesical repair of VVF had significantly higher (106.56±10.46 min) operating time than transvesical repair (95.08±7.6 min) P <0.001. There was no significant difference regarding intraoperative blood loss between the extravesical (365.42±81.29 mL) and transvesical (353.12±73.9 mL) groups; P = 0.44). The extravesical group had a significant shorter hospital stay (62.35±12.25 hours) than the transvesical repair group (85.07±12.0 hours) P < 0.001. Postoperative storage LUTS 6 weeks assessed by Overactive Bladder Symptom Score was significantly lower for extravesical repair (1.75±0.59) than for transvesical repair (6.87±2.24) P = 0.001). This was confirmed by urodynamic evaluation. Two patients (4.2%) in the transvesical group but none in the extravesical group experienced fistula recurrence.
Conclusions The extravesical transabdominal approach for repair of vesicovaginal fistula is a novel, successful, and versatile technique with reduced hospital stay, reduced postoperative LUTS and possibly fewer recurrences than the transvesical technique, and should be considered for all VVF requiring abdominal repair.
The Société International d'Urologie (SIU), which owns and publishes the Société International d'Urologie Journal (SIUJ), does not require authors of papers published in the journal to transfer copyright. Instead, we ask authors to grant an exclusive licence that allows us to publish the article in SIUJ (and any derivative or related products or publications) and that allows us to sub-license such rights and exploit all subsidiary rights.
Authors retain the right to use their own articles for their own non-commercial purposes without seeking explicit permission from SIU.
The SIUJ publication licence expressly defines “non-commercial” as “not primarily intended for or directed towards commercial advantage or monetary compensation.” Although no activity is completely disconnected from commercial activity, the following are generally considered to be non-commercial uses:
- Reproduction of a reasonable number (no more than 100) of print copies of the published paper for personal use (e.g., sharing with colleagues, including in grant applications).
- Posting a copy of the published version of the paper on the author’s own or their institution’s website. The article must be accompanied by this statement: ‘This article has been published in the SIUJ: [full citation; link]’.
- Inclusion of the paper in a course pack, with a maximum of 100 copies to be used in the author’s institution. The copies must include the following acknowledgement: ‘This article has been published in the SIUJ: [full citation; link].’
As the distinction between commercial and non-commercial is not always clear, authors are strongly advised to seek permission from SIU for any use that may be considered to have a commercial aspect.
We ask the corresponding author to read the terms of the licence and then to grant this exclusive licence on behalf of all authors by indicating agreement to the following statement:
