What's new in slings: an update on midurethral slings

Surgical management of female stress incontinence has progressed rapidly over the past decade. The purpose of this review is to provide up-to-date information regarding surgical outcomes of midurethral slings and to discuss management of sling complications. Additionally, the newer commercially available products will be outlined and the data comparing new versus established techniques will be examined.

Long-term data are available for the Tension-free Vaginal Tape procedure which demonstrates durable efficacy. Comparisons between the Tension-free Vaginal Tape and Suprapubic Arch sling procedure demonstrate no significant difference in cure rates or complications. In an effort to avoid the retropubic space, the transobturator slings were developed and short-term data suggest similar efficacy to the transabdominal techniques. The transobturator approach, while limiting abdominal complications, is not without its own complication profile. Increased experience with synthetic mesh in vaginal surgery has allowed for a more systematic approach to managing mesh erosions.

The literature indicates that midurethral slings, despite the specific approach, are efficacious and an important therapy in managing stress incontinence. Prospective data will be needed before the surgeon can determine if the new products and techniques are truly an improvement over the existing products or merely a proprietary modification.
