Fistule vésico-vaginale après bandelette transobturatrice

Abstract

The transobturator approach is gradually replacing the retropubic approach for the treatment of female stress urinary incontinence and suburethral tape. The major argument in favour of this approach is the decreased risk of bladder injury during insertion of the needles, which nevertheless remains a minor complication. Provided another more median approach is used in closer contact with the bone, followed by prolonged bladder catheterization for 24 to 48 hours, this complication has no consequences. However, the authors report a case of bladder injury during insertion of transobturator tape (TOT) in a patient with no particular history, attributable to the technique itself as it occurred during finger dissection towards the obturator membrane. This complication led to secondary formation of a vesicovaginal fistula after insertion of the tape, despite satisfactory repair of the bladder This case illustrates that TOT is not devoid of risks to the bladder; with sometimes even serious consequences. TOT should not be inserted when bladder suture is required. If a fistula is observed after insertion of TOT the tape should be completely removed as soon as possible, but correction of urinary incontinence may persist.
