Özet

Introduction: We aimed to indicate the use of 3D EBCTA (Electron Beam Computerized Tomography Angiography) for renal artery lesions, vascular variants which is crucial to detect before surgery especially for knowledge of extension of the intravascular tumor and partial nephrectomy. Use of EBT for detecting acute abdomen, urolithiasis, hydronephrosis, trauma, urologic congenital problems was discussed. Materials and Methods: Fifty patients (30 man, 20 woman, age range 13-82, mean age 54.2) underwent Electron Beam Computed Tomography (GE-Imatron, C 150 ultrafast CT scanner) Angiography of the renal arteries. Renal tumors of urinary system pathologies were searched. It was emphasized that before 3D technique was performed reviewing the axial images for all necessary information is essential. Results: Several 3-D imaging techniques; MPR (multiplanar reconstruction), MIP (maximum intensity projection) and VR (volume rendering) images were used in demonstrating stenosis of the renal arteries. Accessory and main renal arteries easily depicted and stenosis has been shown. In our study, among fifty renal angiography patients, 21 had stenosis of the renal arteries with a variety of percents. A total of 12 accessory renal artery (five left, seven right) were detected. In suspected urolithiasis conditions not only the calculi and its location, hydronephrosis are detected accurately, but also some situations that mimic calculi (eg. pheloboliths) are recognized. EBCT with its 3D techniques found accurate and useful for renal vascular anatomy as a noninvasive test to delineate renal tumors and renal anatomy prior to nephron sparing surgery because it is known to conserve of normal renal parenchyma adjacent to tumor. Conclusion: EBCT with its non invasive three dimensional techniques is easy to apply, functional and accurate for neoplasms, for renal vascular anatomy, UPJ stenoses and for renal artery stenosis. EBT is also valuable to apply in acute abdomen, trauma patients.
