Modern Pathogenetic Aspects and Updates on Diagnostic Modalities of Urolithiasis Development: A Review

This review critically analyzes current insights into the pathogenesis and diagnostics of urolithiasis from molecular, genetic, and clinical viewpoints. Urolithiasis, affecting 1–15% of the global population, results from imbalances between urinary crystallization promoters (e.g., calcium, oxalate) and inhibitors (e.g., citrate, magnesium), leading to stone formation. Five main theories explain its mechanisms: Free Particle and Fixed Particle Theories, Randall’s Plaque Hypothesis, the Blocked Lymphatic Theory, and the Vascular Theory. Modern understanding highlights its polyetiological nature, involving genetic polymorphisms (e.g., VDR, ORAI1, CASR) and environmental factors. Diagnostic methods include urine and serum analysis, stone composition techniques (e.g., infrared spectroscopy), and imaging—ranging from ultrasound to CT. Emerging tools like parametric MRI and biomarker detection offer improved specificity. A personalized diagnostic approach, integrating metabolic, genetic, and imaging data, is essential for effective treatment and prevention of this complex condition.
