目的:探讨肾脏数字化三维重建模型在腹腔镜下肾肿瘤根治术中的临床应用价值。方法:选取南方医科大学珠江医院2015年1月~2016年3月40例肾细胞癌患者,其中20例患者依据CT数据,利用mimics17.0软件于术前进行患侧肾脏数字化三维重建,并利用三维模型进行术前规划和术中应用(A组);其余20例患者使用CT图像进行术前规划和术中应用(B组)。对患者基本信息、手术时间、出血量、并发症发生率、平均住院天数等进行统计学分析。结果:40例患者都成功行腹腔镜手术。数字化肾肿瘤三维模型能够直观地反映肾动脉主干及其分支,副肾动脉的数量,肾静脉与动脉的位置关系以及肾蒂血管因肿瘤压迫而造成的变异等(A组)。A、B两组平均手术时间分别为(133.0±45.4)min和(160.5±39.5)min,差异有统计学意义(P<0.05);A、B两组估计出血量为(92.5±36.4)ml和(89.5±41.2)ml,并发症发生率为5%和10%,总住院天数(12.6±4.1)d和(12.0±2.8)d,差异均无统计学意义(P>0.05)。结论:数字化肾脏三维重建技术可安全有效地应用于腹腔镜下肾肿瘤根治术中,并可缩短手术时间。 Objective: To investigate the clinical application value of digitalized three-dimensional reconstruction model of kidney in laparoscopic radical nephrectomy. Methods: Forty patients with renal cell carcinoma from January 2015 to March 2016 in Zhujiang Hospital of Southern Medical University were enrolled. Twenty patients underwent digital three-dimensional reconstruction of ipsilateral kidney using mimics17.0 software based on CT data. Three-dimensional model of preoperative planning and intraoperative application (A group); the remaining 20 patients using CT images for preoperative planning and intraoperative application (B group). The basic information of patients, operation time, amount of bleeding, the incidence of complications, the average number of days in hospital for statistical analysis. Results: All 40 patients underwent laparoscopic surgery successfully. The three-dimensional model of digital renal tumor can intuitively reflect the main artery and its branches, the number of the accessory renal artery, the location of the renal vein and the artery, and the variation of the renal pedicle blood vessel due to the tumor compression (Group A). The mean operative time in group A and group B was (133.0 ± 45.4) min and (160.5 ± 39.5) min, respectively, with statistical significance (P <0.05). The estimated amount of bleeding in groups A and B was (92.5 ± 36.4) And (89.5 ± 41.2) ml respectively. The complication rates were 5% and 10%. The total length of hospital stay was (12.6 ± 4.1) days and (12.0 ± 2.8) days respectively. There was no significant difference between the two groups (P> 0.05). Conclusion: Three-dimensional reconstruction of kidney can be used safely and effectively in laparoscopic radical nephrectomy and can shorten the operation time.
