OBJECTIVE
The aim of this study was to demonstrate the advantages of C-arm cone beam computed tomography for imaging guidance of laparoscopic radical nephrectomy (LRN).
METHODS
Four patients referred to the authors' institution for LRN were included in this study. To visualize the renal vascular anatomy, the Iopamiron 300 contrast agent was injected intravenously. The surgeon could adjust the viewing angle of the images and rotate the reconstructed three-dimensional (3D) image manually by using a mouse-like controller. Using the near real-time 3D navigation images, the surgeon was able to recognize the renal vascular anatomy, and more easily perform the LRN.
RESULTS
All procedures were successfully performed with a satisfactory diagnostic yield or therapeutic effect without procedure-related complications.
CONCLUSION
This novel technology has great potential for application in LRN because it enables accurate depiction of the renal vessels and increases surgeon confidence.
目的
本研究旨在证明C形臂锥束计算机断层扫描在腹腔镜根治性肾切除术（LRN）影像引导方面的优势。
方法
本研究纳入了四名转诊至作者所在机构接受LRN的患者。为了可视化肾血管解剖结构，静脉注射了碘帕醇300造影剂。外科医生可以通过类似鼠标的控制器调整图像的视角并手动旋转重建的三维（3D）图像。利用近实时3D导航图像，外科医生能够识别肾血管解剖结构，并更轻松地进行LRN。
结果
所有手术均成功完成，诊断率或治疗效果令人满意，且无手术相关并发症。
结论
这项新技术在LRN中具有巨大的应用潜力，因为它能够准确描绘肾血管并增强外科医生的信心。
