A new device for the treatment of female stress urinary incontinence

Treatment for stress urinary incontinence (SUI) comprises a broad range of possible interventions. Non-surgical options include absorbent pads, vaginal weights and cones, biofeedback and minimally invasive techniques such as urethral bulking agents (UBAs). Surgical interventions range in complexity from sling surgery and suspension techniques to more major surgeries such as burch colposuspension. Each option has its challenges and limitations. This paper will focus on UBAs, which are implantable materials whose purpose is to augment urethral tissue function and restore continence. The characteristics required of such materials, and the challenges to be overcome when incorporating them in a successful product design, will be described and discussed. Particular attention will be given to the latest developments in the administration of polydimethylsiloxane elastomer UBA.
