摘要:
目的探索利用Uromedix-3D肾脏三维重建软件快速准确获取肾脏三维立体图像来指导泌尿外科手术的可行性。方法 获取2015年12月~2018年10月我院肾脏病变患者肾脏增强CT薄层原始数据,利用自主研发的Uromedix-3D系统分别重建出 正常肾脏组织、血管、集合系统及病变组织的三维立体可视化结构,并对各结构进行测量实现解剖结构关系数据化用于指导手 术。结果完成三维重建工作173例,重建时长为31.24±2.012 min,其中肾肿瘤147例(84.9%),肾肿瘤左右侧分布无明显差别, 肾肿瘤合并瘤栓2例,其余病种包括UPJO、肾结石、腹膜后肿物等。完成肾动脉重建工作170例,最精确达到7级动脉分支,5级 动脉分支及其以上有109例(64%);其中共发现肾动脉变异37例,包括副肾动脉24例、2支及以上肾动脉13例。完成静脉重建 工作共164例,最精确达到4级静脉分支,2级静脉分支及以上共138例(84%)。结论Uromedix-3D系统利用增强CT原始数据 能够准确、高效重建人体肾脏及病变组织的三维立体结构,为术前充分了解病变空间解剖关系及术前规划提供客观依据。
Abstract:
Objective To explore the feasibility of rapid and accurate three-dimensional (3D) image reconstruction using Uromedix-3D software for urological surgery. Methods The original renal thin-slice enhancement CT data were obtained from patients with kidney lesions treated in our hospital between December, 2015 and October, 2018. The self-developed Uromedix- 3D system was used to reconstruct the normal kidney structures, blood vessels, collecting systems and the lesions. The spatial anatomic relationships of the structures were measured and digitized for surgical planning. Results 3D reconstruction of the kidneys was performed in a total of 173 cases, and the mean time for reconstruction was 31.24±2.012 min. Of these cases, 147 (84.9%) had renal tumors, and 2 had renal tumors with tumor thrombus. In addition to renal tumors, the Uromedix-3D system was also used for reconstructing other lesions including UPJO, kidney stones and retroperitoneal masses. Renal artery reconstruction was performed in 170 cases, which allowed observation of the precise terminal branches (up to 7th grade arterial branch) of the artery; 109 (64%) cases showed the 5th grade arterial branch or above. Renal artery variations were detected in 37 cases, including accessory renal artery (24 cases) and multiple renal arteries (13 cases). The renal veins were reconstructed in 164 cases, and second grade or above (up to the 4th grade) vein branches were observed in 138 (84%) cases. Conclusions Uromedix-3D system can accurately and efficiently reconstruct the 3D structure of human kidneys and the renal lesions based on enhanced CT data. The reconstructed 3D model allows objective assessment of the spatial anatomical relationship of the lesions to provide assistance in surgical planning.
