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