Pearls and pitfalls in the diagnosis of ureterolithiasis with unenhanced helical CT. 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.


Nonenhanced helical CT and US in the emergency evaluation of patients with renal colic: J Comput Assist Tomogr ; Ureterolithiasis signs on unenhanced helical computed tomography: 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.

Pode ser graduado em leve, moderado e grave. Both methods were employed to evaluate the size of the kidneys, hydronephrosis and the size and location of ureteral stones.

Perirenal hyperdensities, periureteral edema and the halo sign were also assessed by unenhanced helical computed tomography.
