PY - 2009 T2 - CURRENT Diagnosis & Treatment: Nephrology & Hypertension AB - Definitive diagnosis is via passage or removal of stone material; material passed should be retrieved and analyzed to determine composition.Diagnosis is also made by radiologic visualization of stones; composition may be inferred from Hounsfield units, but only analysis is definitive.Typical history of renal colic is suggestive but not diagnostic in the absence of one of the above.Underlying causes of stone formation can usually be determined by an organized evaluation of urine and serum chemistries.
