Answer

Answer

On sonograms, calculi may be confused with high-grade TCCs, which can be densely echogenic. No sonographic features are specific for TCC, and many filling defects within the renal collecting system and bladder may have a nonspecific appearance. In addition, ultrasonography is limited in its capacity to depict nondilated ureters.
