Laparoscopic donor nephrectomy has become the accepted method of harvesting the kidney at many institutions because of multiple advantages over open donor nephrectomy. Spiral computed tomographic (CT) angiography provides accurate information of renal vascular anatomy and has become an accepted method of preoperative evaluation of potential laparoscopic renal donors. More recently, multidetector CT (MDCT) provides more detailed datasets compared with single-detector spiral CT and has been used for preoperative evaluation of laparoscopic donor nephrectomy to provide accurate anatomic information. MDCT (especially 16- and 64-slice MDCT) angiography has advantages over single-detector helical CT due to rapid scan time that allows coverage of a large volume of interest with higher spatial and temporal resolutions. In this article, we review the current status of MDCT angiography in the evaluation of laparoscopic renal donors and potential advantages of using this technology.
由于与开放性供肾切除术相比具有多种优势，腹腔镜供肾切除术已成为许多机构公认的获取肾脏的方法。螺旋计算机断层扫描（CT）血管造影可提供肾脏血管解剖结构的准确信息，已成为术前评估潜在腹腔镜肾供体的公认方法。最近，与单排螺旋CT相比，多排探测器CT（MDCT）能提供更详细的数据集，并已用于腹腔镜供肾切除术的术前评估，以提供准确的解剖信息。MDCT（尤其是16层和64层MDCT）血管造影优于单排螺旋CT，因为其扫描时间短，能够以更高的空间和时间分辨率覆盖大量感兴趣区域。在本文中，我们回顾了MDCT血管造影在评估腹腔镜肾供体方面的现状以及使用该技术的潜在优势。
