The Macroplastique Implants is an injectable urethral bulking agent
to treat adult female stress urinary incontinence primarily due to intrinsic sphincter deficiency.
Injectable Teflon was widely used as a urethral bulking agent in the 1950s and 1960s and was effective, but it has been largely abandoned because of fear that the Teflon would migrate to other tissues, as well as other safety issues.
That leaves two materials--collagen and microcarbon beads--that have been approved by the Food and Drug Administration as urethral bulking agents.

Uryx improved stress urinary incontinence comparably or better than Contigen 12 months after treatment in a multicenter study presented at the annual meeting of the American Urogynecologic Society.
