摘　　要：目的探讨双源CT在腹腔镜保留肾单位手术(LNSS)治疗T1a期肾癌术前评估中的应用价值。方法对60例T1a肾癌患者行双源CT检查,分别探查患侧肾脏血管解剖结构、肾肿瘤大小、位置、毗邻关系及对侧肾脏的相关情况等指标,并与LNSS术中所见及病理结果对比,研究两者的相关性。结果双源CT显示的患侧肾脏血管解剖结构、肿瘤大小、位置与LNSS术中所见均无统计学差异(均P>0.05),而且显示的肿瘤侵入肾实质深度以及与周围血管、集合系统的毗邻关系与病理结果具有一致性(Kappa值=0.949、0.872、0 936,均P<0.05)。结论双源CT对LNSS治疗T1a期肾癌能更好的进行术前评估,具有较高的临床应用价值。Objective To evaluate the application of dual source CT （DSCT） in laparoscopic nephron- sparing surgery （LNSS） for patients with T1a renal tumor. Methods Sixty patients with T1a renal tumors underwent DSCT scan before LNSS. Multiplanar reformation,volume- rendered and maximum intensity projection images were created for measuring the anatomic structure of artery and vein, tumor size, location and the spatial relationship between the tumors and surrounding tissue, and the contralateral renal.The images were compared with those observed in LNSS and pathological results. Results There were no differences in the anatomic structure of artery and vein, tumor size and location between DSCT images and those observed in LNSS（P〉0.05）;and the concordances between DSCT images and pathological results in the invasion depths, spatial relationship between the tumors and the surrounding blood vessel, renal col ecting system were satisfactory （Kappa value=0.949, 0.872 and 0.936, respectively;P〈0.05）. Conclusion DSCT is an effective preoperative assessment tool in LNSS for T1a renal tumors.
