比较三维腹腔镜与传统二维腹腔镜在肾部分切除术中的疗效。

我们回顾性分析2016年5月至2019年10月我组收治的行肾部分切除术的78例患者。观察组37例行三维腹腔镜肾部分切除术，对照组41例行传统二维腹腔镜肾部分切除术。比较两组间围手术期各项指标的差异。

两组患者在性别、年龄、肿瘤侧别、肿瘤大小、RENAL评分、体质量指数等一般资料方面差异无统计学意义（P>0.05）。观察组热缺血时间（WIT） （22.3±4.6）min、肾缝合时间（14.7±3.1）min短于对照组（25.8±5.0）min、（17.5±4.0）min，差异有统计学意义（P<0.05），同时观察组术后血清肌酐变化值（8.4±5.5）μmol/L小于对照组的（12.4±7.0）μmol/L，差异有统计学意义（P<0.05）。而手术时间、术中出血量、肿瘤切除时间、术后住院天数差异无统计学意义（P>0.05）。

三维腹腔镜肾部分切除术由于肾脏创面缝合时间较短，可减少肾脏热缺血时间，对保护患者术后肾功能有一定意义，值得推广应用。

To compare the efficacy of 3D laparoscopy and traditional 2D laparoscopy in partial nephrectomy.

From May 2016 to October 2019, 78 patients who needed partial nephrectomy were randomly divided into two groups. 37 patients in the observation group underwent 3D laparoscopic partial nephrectomy, while the others in the control group underwent conventional 2D laparoscopic partial nephrectomy. The differences of perioperative parameters between the two groups were compared.

There was no significant difference in gender, age, sides, tumor size, RENAL score, body mass index and other general information between the two groups (P>0.05). In the observation group, the warm ischemia time (WIT) (22.3±4.6) min and renal suture time (14.7±3.1) min were shorter than those in the control group (25.8±5.0) min and (17.5±4.0) min, and the differences were statistically significant (P<0.05). At the same time, the postoperative changes in serum creatinine of the observation group (8.4±5.5) μmol/L was smaller than the control group (12.4±7.0) μmol/L, and the differences were significant (P<0.05).There were no significant differences in operation time, blood loss, tumor resection time and postoperative hospitalization days (P>0.05).

The use of 3D laparoscopy in partial nephrectomy can reduce the WIT because of the shorter suture time. Which is of certain significance for the protection of postoperative renal function of patients and is worth popularizing.
