Absorbable Polydioxanone Monofilament Suture with Reverse Cutting Needle

Polydioxanone Suture, also known as PDS II, is a type of synthetic, absorbable suture made from a polymer of paradioxanone. It has greater initial tensile strength than other synthetic absorbable sutures and retains its strength for an extended period of time, making it suitable for tissues that require prolonged approximation under tension. It is often used in bladder surgery due to its low reactivity and ability to maintain integrity in infected tissues and urine.

Polydioxanone (PDS II) is a synthetic, absorbable, monofilament suture made from a polymer of paradioxanone.  It has greater initial tensile strength than polyglycolic acid and polyglactin 910 but has the poorest knot security of all the synthetic absorbable sutures.24  The suture retains 74% of its tensile strength after 2 weeks, 50% after 4 weeks, and 25% after 6 weeks.  There is minimal absorption by 90 days and absorption is not complete until 6–7 months after implantation.9  This retention of strength after implantation is an advantage over other synthetic absorbable sutures and is useful wherever extended approximation of tissues (up to 6 weeks), under tension, is required.35  PDS II is stiff and more difficult to handle than Dexon or Vicryl, but slides easily through tissue.  PDS II was developed to improve the handling characteristics of the original form.  It has low reactivity and maintains integrity in infected tissues and in urine and is often used in bladder surgery.36  Its long retention time may act as a nidus for calculus formation in patients with a history of urinary calculi.  However, it is suitable for use in a wide variety of tissues.
