Oral calcium tolerance and urinary cyclic AMP in urolithiasis.
Oral calcium tolerance and urinary cyclic AMP testing was used in the evaluation of 61 unselected patients with stones. The oral calcium tolerance test was easy to perform and was useful in defining several distinct metabolic abnormalities contributing to calculous formation. Oral calcium tolerance testing is more precise than twenty-four-hour urinary calcium determination and should provide a means of determining proper medical treatment of urolithiasis. Urinary cyclic AMP was disappointing as a measure of parathormone activity.
