title: [Radiologic and biochemical studies of urinary lithiasis].
abstract: Clinical investigations of a patient with urolithiasis include a careful history and radiological and biochemical evaluation. Stone analysis by infrared spectrophotometry remains the most important step. These investigations are essential in order to understand why a patient developed urolithiasis and, most importantly, how to avoid its recurrence in the future. Simple exams are often enough in a patient with a single urolithiasis episode. But biochemical evaluation should be extensive in a child, or an adult with several urolithiasis episodes or with renal insufficiency.
