目的:探讨双源CT三维血管及尿路成像技术在活体肾移植供肾者术前评估中的临床应用价值。方法:使用德国西门子公司双源螺旋CT(SOMATOM Definition 2008G)对本院56例供肾者行动脉期、静脉期、分泌期3期扫描。扫描数据经三维重建专用软件处理,获得肾脏、肾动脉、肾静脉及肾盂输尿管三维立体图像。术前根据重建结果慎重选择一侧作为供肾,再将术中所见与CT结果进行比较。结果:三维图像很好地反映了肾脏血管、肾盂和输尿管的解剖形态。其中双侧均为单支动脉44例,3支动脉且开口于腹主动脉3例,双侧或单侧双支动脉9例,肾静脉显示为3支1例,双支2例;肾盂及输尿管显示均未见明显畸形;术中情况与三维图像显示情况比较,动脉吻合率达100%,静脉吻合率达为82%,肾盂输尿管吻合率达100%。结论:双源CT三维成像技术能反映真实的肾脏血管、肾盂和输尿管的解剖形态,为活体肾移植供肾者术前评估提供了有用价值。
Objective: To investigate the clinical value of three-dimensional dual-source CT angiography and urography in the preoperative evaluation of living donor renal transplant recipients. Methods: Fifty-six patients with renal donors in our hospital were scanned with SOMATOM Definition 2008G during the arterial phase, venous phase and secretory phase. Three-dimensional reconstruction of the scanned data was processed by special software to obtain three-dimensional images of kidney, renal artery, renal vein and pelvis and ureter. According to the reconstruction results before surgery to choose one side as the donor kidney, and then see intraoperative findings and CT results were compared. Results: The three-dimensional images well reflect the anatomy of the renal vessels, pelvis and ureter. There were 44 cases of single artery, 3 arteries in 3 cases, 3 cases of abdominal aorta opening in both sides, 9 cases of bilateral or unilateral double branches, 3 cases of renal vein in 1 case and 2 cases of double branch. The renal pelvis and Ureter showed no significant deformity; intraoperative and three-dimensional images show the situation compared to 100% arterial anastomosis, venous anastomosis rate was 82%, ureteropelvic anastomosis rate of 100%. Conclusion: Dual-source CT three-dimensional imaging technology can reflect the true anatomy of renal vessels, pelvis and ureter, and provide useful value for preoperative assessment of living donor kidney donor.
