Management of patients with stress urinary incontinence after failed midurethral sling

Surgical failure rates after midurethral sling (MUS) procedures are variable and range from approximately 8-57% at five years of followup. The disparity in long-term failure rates is explained by a lack of long-term followup and lack of a clear definition of what constitutes failure. A recent Cochrane review illustrates that no high-quality data exists to recommend or refute any of the different management strategies for recurrent or persistent stress urinary incontinence (SUI) after failed MUS surgery. Clinical evaluation requires a complete history, physical examination, and establishment of patient goals. Conservative treatment measures include pelvic floor physiotherapy, incontinence pessary dish, commercially available devices (Uresta (R), Impressa (R)), or medical therapy. Minimally invasive therapies include periurethral bulking agents (bladder neck injections) and sling plication. Surgical options include repeat MUS with or without mesh removal, salvage autologous fascial sling or Burch colposuspension, or salvage artificial urinary sphincter insertion. In this paper, we present the available evidence to support each of these approaches and include the management strategy used by our review panel for patients that present with SUI after failed midurethral sling.
