physical characteristics of crushed stones

A family history of renal calculi is present in 55&percent; of patients with recurrent stones. Stones occur three times more frequently in men with a family history of stones. The physical exam typically shows a distressed patient, often writhing and constantly moving while trying to find a comfortable position.
