“…Evaluation usually is dependent on radiologic studies. 4 Transitional cell carcinoma has been described as having five different appearances on excretory urogram. These include (1) a discrete filling defect within the pyelogram, (2) a filling defect within a dilated calyx, (3) calyceal obliteration, (4) hydronephrosis with renal enlargement, and (5) reduced function without renal enlargement.…”

Transitional cell carcinoma, while being the most common tumor of the urinary tract overall, is a relatively uncommon tumor when the upper urinary tract is considered separately. In the kidney, adenocarcinoma occurs more often than transitional cell carcinoma by a ratio of 4:1 to 5:1. 1 When transitional cell carcinomas occur in the upper urinary tract, they are usually located in the proximal ureter or the renal pelvis. 2 The typical presentation of transitional cell carcinoma on excretory urograms and CT scans is a filling defect produced by a central, solid tumor that does not distort the renal outline. 1 We report a transitional cell carcinoma obstructing a calyceal diverticulum that appeared as a peripheral complex cystic mass projecting laterally and distorting the upper pole of the kidney. The possibility that a peripheral cystic upper urinary tract lesion might be a transitional cell carcinoma, rather than a renal adenocarcinoma, has important implications for both the clinician and surgeon. CASE REPORTA 67 year old white man had acute onset of left flank pain. He denied hematuria and other urinary symptoms. He reported some decrease in energy but was otherwise in good health. His past medical and surgical history was unremarkable. He had stopped smoking 30 years ago, after a prior smoking history of 22 pack years. On physical examination he was found to have a benign abdomen without costovertebral angle tenderness.Excretory urography was performed, which revealed a 9 cm mass projecting laterally from the upper third of the left kidney. The mass had a thick wall medially and inferiorly and was of low density centrally. The left collecting system was not well visualized. Ultrasonographic examination showed a fluid-filled mass containing amorphous, turbid debris (Fig. 1). Some central areas were hyperechoic and were thought to represent hemorrhage into the substance of the mass.By CT examination, the mass appeared to arise from the lateral aspect of the left kidney. It was cystic but had a 2 cm

“…1,2 The diagnostic imaging modalities considered most effective for the ureter are IVU and antegrade and retrograde pyelography. [2][3][4] IVU depends on kidney function, and although it is able to demonstrate a filling defect, it is not always possible to accurately characterize the nature of the defect. Inability to define the exact nature of a filling defect also restricts the usefulness of antegrade and retrograde pyelography.…”

We present our experience with transabdominal ultrasonographic diagnosis of ureteral tumors. During the years 1989 to 1998, 16 patients were diagnosed as having ureteral tumors. These patients were referred for sonographic examination for evaluation of hematuria (seven patients) or flank pain (four patients) or for follow‐up screening in patients who were asymptomatic but at high risk for transitional cell carcinoma because of known past bladder tumor (five patients). Ten of these patients underwent intravenous urography examination, three patients had retrograde pyelography, and 11 patients underwent CT scanning. Ultrasonography revealed the ureteral tumors in all 16 patients, which appeared as hypoechoic intraluminal soft tissue. Three tumors were localized in the upper ureter, four in the middle ureter, and nine in the distal ureter. The degree of ureterohydronephrosis was minimal (two cases), mild (five cases), moderate (eight cases), or severe (one case). Eleven tumors caused local widening of the ureteral diameter. On intravenous urography, four patients had a nonfunctioning kidney, three patients had unexplained ureterohydronephrosis, and three patients showed ureteral filling defects, of which only two had irregular contours. On retrograde pyelography, two patients had filling defects (one of which with smooth margins), and one had a truncated ureter. On CT the tumor was clearly demonstrated in only seven patients. We found that ultrasonography can be a useful diagnostic tool in the workup of ureteral tumors.
