When it comes to ureteral stents, urine calcium (Ca) and magnesium (Mg) salt deposits can contribute to stent complications such as encrustation.1,2 The cause and rate of encrustation is multifactorial and can include factors such as body chemistry and medical condition of the patient, stent indwell time, and surface material or properties of the stent.2-4 The Tria Stent is the only commercially available stent that may help control the accumulation of both Mg and Ca salts.5,6

What happens when ureteral stents are forgotten?

  • 13 out of 100 ureteral stents may be forgotten.7
  • ~10 of 13 stents (76%) may become encrusted within 6 months.3  This can result in increased risk of infection and obstruction.8
  • An average of 2 procedures is required for stent removal.3
