Kidney stones typically form from minerals and compounds crystallizing in urine. These stones can cause anything from mild discomfort to intense pain and may require medical intervention. Calcium-based stones, especially calcium oxalate, are most common, traditionally attributed to physical factors like diet and hydration. However, a study by UCLA researchers challenges this by suggesting bacteria play a role in stone formation. The study, published in the Proceedings of the National Academy of Sciences, discovered bacteria embedded in stones, forming biofilms that act as scaffolding for crystal growth.
Unlike infection-driven struvite stones, calcium-based stones were thought noninfectious until researchers found bacteria like E. coli within them. These findings indicate that bacterial biofilms can serve as a foundation for calcium oxalate crystals, altering their growth patterns and influencing stone size and structure. This discovery opens avenues for new prevention and management strategies for this condition.
Maintaining a healthy kidney microbiome is crucial. Strategies include moderating oxalate intake, staying hydrated, minimizing unnecessary antibiotic use, and embracing a balanced diet while promoting a physically active lifestyle. These practices may help safeguard against kidney stones while supporting overall urinary health.
