title: [The usefulness of URO-CT scan in the diagnosis of small urinary lithiasis. Case report].
abstract: OBJECTIVE
  To report one case of microlithiasis diagnosed by Uro-CT scan (with multidetector CT scan).
  
  
  METHODS
  We describe the case of a middle age male patient with symptoms of renal colic and hydronephrosis without and objective cause detected on IVU who underwent CT scan.
  
  
  RESULTS
  The Uro-CT scan showed a 2 mm microlithiasis in the most distal portion of the left ureter with edema of the adjacent area causing obstruction.
  
  
  CONCLUSIONS
  The Uro-CT scan is an useful imaging technique for the diagnosis of microlithiasis, which can be missed by other imaging tests.
