A simplified sensitive method for the analysis of renal calculi

Area of Science:

• Nephrology
• Analytical Chemistry
• Biochemistry

Background:

• Renal calculi (kidney stones) pose a significant health burden.
• Accurate stone composition analysis is crucial for diagnosis and treatment.
• Existing methods may require larger sample sizes or be less convenient.

Purpose of the Study:

• To present a simple and convenient method for renal calculi analysis.
• To enable quantitative and qualitative assessment of common stone components.
• To validate the method's efficacy on small sample sizes.

Main Methods:

• Development of a straightforward analytical procedure for renal calculi.
• Quantitative estimation of oxalate, urate, calcium, magnesium, xanthine, and phosphate.
• Qualitative analysis for ammonia, carbonate, and cystine.

Main Results:

• The method successfully quantifies major inorganic and organic components of kidney stones.
• Qualitative detection of ammonia, carbonate, and cystine is achieved.
• The analysis is feasible with minimal sample mass (as low as 1 mg).

Conclusions:

• A practical and efficient method for renal calculi analysis is established.
• This technique facilitates detailed characterization of kidney stone composition.
• The method supports clinical understanding and management of nephrolithiasis.
