What is the most prevalent type of urinary stone?

Calcium oxalate stones are the most prevalent type of urinary stone, accounting for approximately 70-80% of all kidney stones. They form when there is an excess of calcium and oxalate in the urine, which can precipitate and crystallize into stones. Factors contributing to the formation of calcium oxalate stones include dehydration, high dietary intake of oxalate-rich foods, certain metabolic disorders, and low urinary volume.

Understanding the formation and prevalence of calcium oxalate stones is crucial for developing dietary and lifestyle recommendations for those at risk of stone formation. For instance, individuals may be advised to increase hydration and manage dietary oxalate intake to reduce stone recurrence. The prevalence of these stones highlights the importance of monitoring calcium and oxalate levels in patients, making calcium oxalate stones a key focus in renal nutrition and management strategies.
