目的探讨CT导引下活检枪在肾穿刺中的应用。方法在CT定位下,用活检枪对14例肾病患者进行肾穿刺活检。活检枪用18-16G自动Tru-Cut针,针芯凹槽以20mm长度最佳。选择肾下极为穿刺目标。结果14例经皮肾穿刺均穿刺成功,所取组织均获得足量的病理组织块,所获肾小球最少5个,最高20个,平均12.5个。无一例发生严重并发症。结论CT作为新的导向设备,对于腹膜后腔器官显示清晰,而活检枪所取组织块较多,且并发症较少,二者结合可作为较理想的肾穿刺方法。
Objective To investigate the application of CT guided biopsy gun in renal puncture. Methods Totally 14 patients with renal disease underwent biopsy with a biopsy gun under CT localization. Biopsy gun with automatic 18-16G Tru-Cut needle, needle groove to 20mm length of the best. Select the most suitable puncture the target under the kidney. Results All 14 cases of percutaneous nephrolithotomy were successfully punctured, and all the tissues obtained obtained enough pathological tissue pieces. The number of glomeruli obtained was at least 5 and the maximum was 20, with an average of 12.5. No case of serious complications. Conclusions As a new guiding device, CT can clearly show the retroperitoneal organs. However, the biopsy gun has more tissue sections with fewer complications, and the combination of the two can be used as a more ideal method of renal puncture.
