Renewed interest in the pubovaginal sling procedure for stress urinary incontinence has occurred in response to recent reports of poor durability and inconsistent efficacy associated with simple cystourethropexy. Many of the failures are felt to represent patients with an unrecognized component of intrinsic sphincteric deficiency. Historically slings have a favourable cure rate, but have been perceived as having unacceptably high rates of prolonged urinary retention and secondary detrusor instability. This article reviews the preoperative evaluation and indications for pubovaginal slings, describes the evolution of the current techniques, and discusses choice of sling material, surgical approach, results and complications. It is hoped that this review will stimulate interest in this versatile but technically challenging procedure.
