Calcium Oxalate Stones

Calcium oxalate stones are the most prevalent type of kidney stone, forming when calcium binds with oxalate in the urinary tract due to factors like dehydration, high intake of oxalate-rich foods, or certain medical conditions such as hyperparathyroidism and inflammatory bowel disease. These stones can cause severe, intermittent pain in the side and back, pain while urinating, blood in the urine, cloudy or foul-smelling urine, and frequent urination; nausea, vomiting, fever, and chills may occur if an infection develops.

Risk factors for calcium oxalate stone formation include inadequate hydration, genetic predisposition, gastric bypass surgery, obesity, and diabetes. Treatment typically involves increasing fluid intake, dietary modifications (such as lowering oxalate, salt, and protein), and sometimes medications to ease passage or manage pain. Small stones often pass naturally with increased hydration, while larger or obstructive stones may require medical intervention, such as lithotripsy or surgical removal. Preventive measures include a balanced low-oxalate diet and regular monitoring in susceptible individuals.?
