Final answer:
The recommended treatment for calcium oxalate stones is primarily dietary changes, with additional medications if needed. Surgery and lithotripsy are options for stones causing blockage or if they fail to pass.
Step-by-step explanation:
For calcium oxalate stones, the recommended treatment according to the information provided would be dietary changes and possibly taking certain medications. The preventive strategies highlight the need for maintaining adequate hydration by drinking enough water to produce 2 to 2.5 liters of urine daily, adhering to a diet low in protein, nitrogen, and sodium, and restricting intake of oxalate-rich foods. Dietary calcium should be adequate to bind oxalate in the gastrointestinal tract, reducing its absorption and subsequent urinary excretion. In addition, medications such as thiazides (like Hydrochlorothiazide or HCTZ), potassium citrate, magnesium citrate, and allopurinol may be recommended depending on the cause of stone formation. While surgery and other procedures like lithotripsy are used to treat kidney stones that cause blockage or do not pass naturally, these are generally not the first step in treatment unless the stone is too large or causes complications.
