PURPOSE: Computerized tomography (CT) endoscopy is an interactive 3-dimensional image acquired by helical CT. We assess the usefulness of CT nephroscopy in the diagnosis of @entity703 . MATERIALS AND METHODS: Surface rendering CT nephroscopy was performed after intravenous administration of contrast agent and furosemide in 32 @entity1 with suspected @entity703 . Retrospective review revealed that 23 @entity1 later underwent nephroureterectomy. Two observers blinded to the pathology results independently reviewed the CT nephroscopic and axial CT images of the 23 @entity1 to @entity530 and to determine the extent of the disease. The CT nephroscopic and axial CT images were correlated with the pathological findings. RESULTS: Pathological examination revealed 4 polypoid, 6 pedunculated, 7 sessile, 1 sessile with ulceration and 6 infiltrating @entity703 in the 23 @entity1 . CT nephroscopy revealed 22 @entity189 (92%) and CT demonstrated 20 (83%). CT nephroscopy was superior to axial CT in detecting 4 pedunculated and 3 infiltrating @entity189 but failed to detect 1 sessile @entity189 which completely replaced the upper portion of a @entity703 associated with infiltrating @entity189 . The CT nephroscopic images correlated well with pathological findings. CONCLUSIONS: CT nephroscopy is useful to visualize the complex morphology of @entity703 noninvasively and is superior to axial CT for the detection of infiltrating and pedunculated @entity189 .
