Abstract Our purpose was to evaluate the accuracy of unenhanced helical computed tomography in the diagnosis of ureteral lithiasis, to establish the frequency of the main computed tomography findings, and to assess and compare the interobserver agreement with the results of conventional intravenous urography.

The most important diagnostic sign of ureterolithiasis is the direct visualization of the stone within the ureter. Both methods were employed to evaluate the size of the kidneys, hydronephrosis and the size and location of ureteral stones.

We concluded that unenhanced helical computed tomography is as efficient as conventional intravenous urography in the evaluation of patients with nephretic colic, is a reproducible method, and avoids the discomfort of the use of intravenous contrast.

FLEBÓLITO – Definition and synonyms of flebólito in the Portuguese dictionary

In this context, we describe many secondary computed tomography signs of ureteral obstruction that may useful in the diagnosis of inconclusive cases, and also quantify the degree of urinary obstruction. However, in some patients with ureterolithiasis stone visualization may be impaired due felbolito stone small size or low attenuation, respiratory artifacts between data acquisitions, low amount of retroperitoneal fat or recent elimination of the stone.
