To create and define standardized in vitro artificial urine models for environments promoting stone formation and to enhance stent-related surface deposition while minimizing excessive bulk precipitation (clarify this term).
Key Findings:
In the CaOx model, surface weight gain increased with calcium concentration, peaking at 200% before decreasing due to bulk precipitation (provide context on significance).
The UA model showed minimal deposition, with the highest weight gain at 600 mg/L uric acid.
The bacterial infection model exhibited the greatest weight gain at pH 6.5, with significant deposits at pH 9.0.
Interpretation:
The developed AU models provide a reliable platform for assessing stent materials and coatings under specific lithogenic conditions, facilitating rapid screening for encrustation resistance (emphasize practical applications).
Limitations:
The study is limited to in vitro conditions and may not fully replicate in vivo environments (expand on applicability).
The artificial urine formulations may not encompass all variations of human urine chemistry.
Conclusion:
The established AU models can serve as effective tools for evaluating stent-related deposition under lithogenic conditions, potentially guiding future stent design and coatings (reiterate clinical impact).
