目的:分析穿刺部位和穿刺针数不同对肾肿瘤穿刺病理诊断的影响。方法:2012年7月~2013年10月使用活检穿刺枪对52例术后切除的肾脏标本行穿刺术,中心区1针,周边区2针。穿刺标本制成病理切片,送病理医师观察并做出诊断。结果:收集标本52例,男30例(57.7%),女22例(42.3%),平均年龄54.9(36~79)岁,肿瘤最大径平均值4.8(2~15)cm。单取肿瘤中心区1针的穿刺成功率为90.4%,取肿瘤中心区与肿瘤周边区2针的穿刺成功率为98.1%,取材中心区与周边区共3针的穿刺成功率为100%。三种取材方式的成功率比较,1针比2针(P=0.035),2针比3针(P=0.201),1针比3针(P=0.007),α=0.0125,穿刺1针与3针存在差异。分别对比在肿瘤中心区与周边区穿刺所获取合格标本的成功率的差异(P=0.22)、肿瘤良恶性诊断的差异(P=1)和肾癌分型诊断的差异(P=0.25)均无统计学意义。结论:肾肿瘤穿刺针数越多,取材的成功率越高,取材3针的成功率可达到100%。在肾肿瘤的不同位置(中心区或周边区)穿刺取材对病理诊断结果的诊断准确性没有影响。
OBJECTIVE: To analyze the influence of puncturing site and puncture needle number on pathological diagnosis of renal tumor puncture. Methods: From July 2012 to October 2013, 52 cases of resected kidneys were punctured using a biopsy puncture gun. The center needle was 1 gauge and the peripheral needle was 2 gauge. Puncture specimens made pathological, sent to the pathologist to observe and make a diagnosis. Results: Totally 52 specimens were collected, including 30 males (57.7%) and 22 females (42.3%) with an average age of 54.9 (36-79) years old. The maximum diameter of the tumors was 4.8 (2-15) cm. The successful rate of puncturing was 90.4% in the center of single tumor and 98.1% in the center of the tumor and in the peripheral area of the tumor. The success rate of puncturing a total of 3 needles in the central area and surrounding area was 100%. The success rates of the three methods were compared with those of the first needle and the second needle (P = 0.035), the second needle and the third needle (P = 0.201), the third needle and the third needle (P = 0.007) There are differences between 3 needles. The difference between the success rate of qualified specimens obtained by puncture in the center of the tumor and the peripheral area was compared (P = 0.22), the difference of benign and malignant tumors (P = 1) and the difference of the classification of renal cancer (P = 0.25) No statistical significance. Conclusion: The more the number of puncture of kidney tumor, the higher the success rate of drawing, the success rate of drawing 3 needles can reach 100%. There is no effect on the diagnostic accuracy of the pathological diagnosis in different locations (center or peripheral area) of renal tumors.
