Polyurethane covered implants were popular in the late 80s but are no longer approved by the FDA nor available in this country. They were unusually good at resisting capsule contracture in the first 5 to 10 years but did have problems with subsequent leakage. The new cohesive gel implants available as either smooth or textured surfaced implants are more durable and generally produce excellent results. I hope that this is useful information for you.RegardsJon A Perlman M.D., FACSDiplomate, American Board of Plastic SurgeryMember, American Society for Aesthetic Plastic Surgery (ASAPS)Beverly Hills, California
