“…Usually, transabdominal sonography can easily identify the renal pelvis, proximal ureter, distal ureter, and bladder and can be used to determine the level of obstruction, but its ability to show pathologic conditions in the mid ureter is limited. [33][34][35] We divided the ureter into proximal and distal portions from the UPJ to the UVJ based on the level of crossing the iliac vessels because no appreciable difference exists in the sensitivity, specificity, and diagnostic accuracy of sonography for detecting urolithiasis based on location. The locations of the 313 calculi in the 291 patients with a sonographic diagnosis consisted of the UPJ in 21 cases, proximal half of the ureter in 96 cases, distal half of the ureter in 69 cases, UVJ in 121 cases, urinary bladder in 5 cases, and urethra in 1 case.…”

“…1 Transabdominal ultrasonography may identify the renal pelvis, proximal ureter, distal ureter, and bladder, and it may determine the obstruction level, 1 although it has limitations in showing pathologic conditions of the mid ureter. [2][3][4] The most common causes of distal ureteral obstructions are ureter stones, and they may be readily identified with TAUS because the urinary bladder provides a good sonic window. 5 However, a gray area persists in the diagnosis of distal ureteral obstructions, particularly those in which there is no evidence of stones on TAUS.…”

“…1 The gray-scale sonographic appearance of TCC confined to the ureter has been reported in only a few patients. 1,2 We present a case of TCC of the ureter diagnosed using power Doppler sonography and spectral analysis.…”
