Abstract
Surgical treatment of stress urinary incontinence changed dramatically with the introduction of the tension-free vaginal tape. Owing to its high efficacy and minimal patient discomfort this new minimally invasive procedure quickly obtained widespread acceptance and superseded the abdominal colposuspension as the gold standard. In the course of success of the original method a number of tension-free vaginal tapes flooded the market, varying in approach and material. These variations may strongly influence the safety, efficacy and long-term results of tension-free vaginal tape and its major modification, the transobturator technique. Therefore, it is the aim of this review to closely illuminate available materials and complications associated with this procedure. An extensive Medline search of the published literature up until 2006 on the subject of stress urinary incontinence was carried out. All sources identified were reviewed with particular attention to the method applied, the properties of the mesh materials and clinical complications. Apart from several technical variations, there are marked differences between the different vaginal sling materials, ranging from absorbable collagens over polypropylene to allografts. Although performed globally in substantial and increasing numbers, minimally invasive techniques for the surgical treatment of stress urinary incontinence are lacking sufficient safety data.
