目的探讨B超引导下自动活检枪经皮肾穿刺活检的成功率、并发症及有关影响因素。方法选择肾下极近外缘处皮质较厚部位,在B超引导下应用自动活检枪进行经皮肾穿刺活检。并运用单因素和多因素统计方法对有关因素进行分析。结果102例肾活检取材成功98例(96.1%),出现并发症9例(8.8%),未出现严重并发症。不同取材长度、穿刺次数与活检成功率无显著关系。Logistic回归分析提示穿刺次数、年龄为促进并发症的危险因素(P<0.05)。结论超声引导下自动活检枪经皮肾脏穿刺术是一种成功率高而且并发症少的方法。肾活检成功率与取材长度、穿刺次数无关,而年龄、穿刺次数增加能增加并发症发生的危险性。
Objective To investigate the success rate, complications and related factors of percutaneous renal biopsy under B-guided automatic biopsy gun. Methods The thick subcutaneous cortical area was selected at the proximal subrenaline. Percutaneous renal biopsy was performed with automatic biopsy gun guided by B ultrasound. And using single factor and multivariate statistical methods to analyze the relevant factors. Results Of the 102 cases, 98 cases (96.1%) were successfully obtained by renal biopsy, and 9 cases (8.8%) had complications. There were no serious complications. There was no significant correlation between the length of different materials and the number of punctures and the success rate of biopsy. Logistic regression analysis showed that the number of punctures and the age were the risk factors to promote the complication (P <0.05). Conclusion Ultrasound-guided automatic biopsy gun percutaneous nephrolithotomy is a method with high success rate and less complications. The success rate of renal biopsy and drawing length, the number of puncture has nothing to do, but the age, the increase in the number of puncture can increase the risk of complications.
