    Standardized artificial urine models were developed to replicate calcium oxalate, uric acid, and infection-induced struvite stone environments.

  • 2

    The calcium oxalate model showed significant stent surface deposition, peaking at 200% weight gain with calcium chloride at 200% concentration.

  • 3

    The uric acid model demonstrated minimal deposition, with optimal weight gain occurring at 600 mg/L uric acid concentration.

  • 4

    In bacterial infection assays, the greatest weight gain occurred at a bulk pH of 6.5, indicating enhanced stent deposition under these conditions.

    These artificial urine models provide a rapid screening platform for evaluating stent materials and coatings against encrustation.
