[The usefulness of URO-CT scan in the diagnosis of small urinary lithiasis. Case report].

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.
