超声引导下自动肾活检穿刺角度的选择

Puncture angle choice of ultrasound guided automatic kidney biopsy in 518 cases

目的通过对518例超声引导下自动肾活检穿刺角度的分析，探讨超声引导下肾活检穿刺的最佳角度。方法在彩色多普勒超声引导下，使用配有穿刺架的3．5MHz探头，分别与水平面成40°（X组）、45°（Y组）、60°（Z组）和70°（P组），进行肾活组织检查穿刺。结果518例患者总成功率为100％，其中，Y组和Z组一次成功率均达100％（Y组164／164；Z组186／186）；X组一次成功率为4718％（22／46），P组一次成功率为84．4％（103／122）。结论超声引导下自动肾活检角度在与水平方向成45°～60°之间安全、成功率较高，且可避免并发症的发生。

Objective To elevate the achievement rate of kidney biopsy puncture through the analysis of puncture angle choice of ultrasound guided automatic kidney biopsy in 518 patients. Methods Under the guidance of color Doppler ultrasound, using the 3.5MHz probe with probe holder,we performed kidney biopsy in the degrees of 40°（group X）, 45°（group Y）, 60°（group Z） and 70°（group P） with the horizontal plane. Results The total achievement ratio is 100 % . The one time success rate in group Y and group Z is 100 % （group Y, 164/164 ;group Z, 186/186） ;group X is 4.8% （22/46）;group P is 84.4% （103/122）.Conclusion The automatic kidney biopsy angle under the guidance of ultrasound should be between 45° and 60° with the horizontal plane which is safe and has higher achievement ratio. In the meantime, complications can be avoided.
