non-absorbable suture

non-absorbable suture

Any suture material—certain silks, synthetics (e.g., polypropylene, polyester or nylon), or wires (for approximating bone in orthopaedics)—which is left in place and subsequently removed. Non-absorbable sutures are used when a mechanical condition (e.g., in the heart, which is in constant motion) or chemical exposure (e.g, in the urinary bladder, which is filled with urine), requires closure material that is more robust than absorbable suture material. Further advantages of non-absorbable suture material include less scarring and a relatively banal immune response.
