Medical management of urolithiasis

Knowledge of the crystalline structure of the calculus provides the basis of the therapeutic plan. Laboratory evaluation depends heavily upon routine urinalysis. Assessment of renal function, serum calcium, phosphorus, uric acid and, in some cases electrolytes is usually indicated, as is urography. General principles of management include maintenance of an ample urine volume, eradication of infection and correction of any obstructing lesions or metabolic abnormalities. Specific antistone regimens are indicated for patients with recurrent urolithiasis.
