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

Ureteral calculi in patients with flank pain: In this context, we describe many secondary computed tomography signs of ureteral obstruction that may useful in the diagnosis of inconclusive cases, and also pdlvico the degree of urinary obstruction.

Assessment of the clinical utility of the rim and comet-tail signs in differentiating ureteral stones from phleboliths.

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.

Interobserver variability in the interpretation of unenhanced helical CT for the diagnosis of ureteral stone disease. Perirenal hyperdensities, periureteral edema and the halo sign were also assessed by unenhanced helical computed tomography.

Spiral computerized tomography in the evaluation of acute flank pain: Both methods were employed to evaluate the size of the kidneys, hydronephrosis and the size and location of ureteral stones.

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. Arch Intern Med ; Radiologic diagnosis of renal colic: Ultrasound diagnosis of ureteral stones: Scand J Urol Nephrol ; A prospective double-blind study was carried out in 25 patients referred for unenhanced helical computed tomography and conventional intravenous urography due to flebollto colic.

However, in some patients with ureterolithiasis stone visualization may be impaired due to stone small size or low attenuation, respiratory artifacts between data acquisitions, low amount of retroperitoneal fat or recent elimination of the stone.

Meaning of “flebólito” in the Portuguese dictionary

Clinical significance of stone analysis. In 21 of the 25 patients, there was agreement between the results of both methods.

The most important diagnostic sign of ureterolithiasis is the direct visualization of the stone within the ureter. Distinguishing pelvic phleboliths from distal ureteral stones on routine unenhanced helical CT: Sinal da cauda de cometa:
