The applications of three-dimensional (3D) CT techniques encompass a spectrum from calculus disease to preoperative planning. With proper selection of display windows and levels, accurate measurement of stone size can be achieved, along with volumetric information. A CT scan with reconstruction may help guide the direction of an endopyelotomy incision away from crossing vessels. The benefits of 3D CT in the evaluation of living renal donors include lower cost and decreased patient morbidity. In renal allograft recipients and other patients, the study may be used to investigate hypertension. Also, 3D CT is invaluable in planning nephron-sparing surgery for renal masses. The ultimate role of this modality rests in the hands of clinicians who can benefit from them and the radiologists who must provide the high-quality images and the interpretive expertise.
三维（3D）CT技术的应用范围涵盖从结石病到术前规划的一系列领域。通过正确选择显示窗口和层面，可以实现结石大小的准确测量以及容积信息的获取。带有重建功能的CT扫描有助于指导肾盂切开术切口方向，避免损伤交叉血管。3D CT在活体肾供体评估中的优势包括成本较低和患者发病率降低。在肾移植受者和其他患者中，该检查可用于研究高血压。此外，3D CT在为肾肿块制定保留肾单位手术方案时具有重要价值。这种检查方式的最终作用掌握在能够从中受益的临床医生以及必须提供高质量图像和解读专业知识的放射科医生手中。
