Abstract

The authors retrospectively analyzed 20 cases of histologically proved renal pelvis and ureteral carcinomaduring recent 12 years in Hanyang University hospital is an attempt to review findings and characteristics of eachdiagnostic modalities. The results were as follows; 1. 18 cases were originated from the renal pelvis and 2 caseswere from the lower ureter. Histologically all cases were papillary growing transitional cell carcinoma, and 65%of them were infiltrative advanced lesions. 2. The most prevalent age group was 7th decade and was more common inmale at the ratio of 4:1. 3. The main symptom was gross hematuria occuring in 85% of cases. WBC and RBC wasfrequently observed in urine microscopy. 4. 14 cases were occured in left side and 6 cases were in right side. Themultiplicity of lesions in the ipsilateral ureter and bladder were observed in 45% of cases. 5. The most commonIVP findings were intraluminal radiolucent filling defects and non-visualization. Findings such as space occupyinglesion, focal calyx obliteration and non-visualization were suggestive of renal parenchymal invasion. 6. GenerallyRGP offered more information and better image than IVP, and was essential for determine the causes ofnon-visualized kidney. 7.The characteristic angiographic findings were mass with evidence of vessel encasement,displacement and prominent pelviuretericartexy. 8. Ultrasonographic findings were solid mass causing seperation ofthe central renal sinus echo. Obliteration of the renal sinus echo with bulky mass was suggestive of renalparenchymal invasion.
