【摘要】 目的探讨计算机体层摄影血管造影(CTA)联合计算机体层摄影尿路造影(CTU)在小肾癌患者后腹腔镜保留肾单位手术(NSS)中的临床应用价值。方法选取50例接受手术治疗的小肾癌患者,依据随机数字表法分为试验组和对照组,每组25例,两组患者均接受后腹腔镜NSS手术,试验组患者术前行CTA联合CTU检查,对照组患者术前行单纯CTA检查。比较两组患者的手术时间、术中热缺血时间、术中出血量及术后住院时间。结果 CTA显示的各种肾血管异常与术中所见一致。试验组患者的手术时间、术中热缺血时间和术后住院时间均短于对照组,试验组患者的术中出血量少于对照组,差异均有统计学意义(P﹤0.05)。结论后腹腔镜NSS中应用CTA联合CTU能够缩短小肾癌患者的手术时间、术中热缺血时间和术后住院时间,减少术中出血量,具有一定的临床应用价值。更多还原

【Abstract】 Objective To evaluate the clinical value of computed tomography angiography(CTA) combined with computed tomography urography(CTU) in retroperitoneal laparoscopic nephron sparing surgery(NSS) for small renal carcinoma. Method Fifty patients treated with retroperitoneal laparoscopic NSS were included and randomly divided as study group and control group, with 25 patients in each group, all the patients received retroperitoneal laparoscopic NSS,and preoperative CTA + CTU examination were performed in study group, while CTA alone was performed for control group before surgery. The operative time, intraoperative warm ischemia time, intraoperative blood loss, and the hospital stay after surgery of the two groups were recorded and compared. Result All findings of renal vascular abnormalities observed in CTA were consistent with those noted during surgery. The operative time, intraoperative warm ischemia time and postoperative hospital stay were shorter in study group than in control group, furthermore, the intraoperative blood loss was also less in study group compared with control group, indicating statistically significant difference(P<0.05).Conclusion The application of CTA combined with CTU in retroperitoneal laparoscopic NSS for small renal carcinoma can significantly reduce the operative time, with decreased intraoperative warm ischemia time and shorter hospital stay,and less intraoperative blood loss, and is clinically applicable.更多还原
