Abstract

Although the excretory urogram, retrograde pyelogram, renal angiogram and ultrasound studies provide formidable competition in renal imaging, CT has advantages over each of these techniques and can provide unique and vital information in evaluating selected renal diseases. CT provide a cross-sectional view of the anatomy, thus delineating more clearly the renal margins and adjacent organs. CT imaging is not dependent on renal function and more easily recognized as a true anatomic portrayal, Furthermore, to discriminate density differences, the nature of renal masses may be determined. Recently we experienced several cases of renal diseases, confirmed with CT which was particuly useful in making in accurate diagnosis than other urologic examinations. Surgery, clinical follow-up and repeated radiologic examinations confirmed the accuracy of CT and there were no cases in which medical of surgical management was inappropriately guided by CT. herein a series of renal disease-polycystic kidney with bilateral radiolucent pelvic stones, angiomyolipoma, renal infarction, renal injury and renal pelvic transitional cell carcinoma were presented and the diagnostic advantages of CT for evaluation of renal diseases were discussed with a review of the literatures.
