ABSTRACT

  Objective:To evaluate the factors in relation to complications of ultrasound2guided automatic renal biopsy.

Methods:All the 511 cases of automatic renal biopsies (18G) were analyzed with single-factor and Logistic regression.

Results:The rate of complications was 7.44% and the complications were mainly minor. The patients with hypertension and acute renal failure had a higher complication rate (17.92% and 29.17% respectively), while those with nephritic syndrome had a lower complication rate (5.77%) (OR: 1.055~3.683 ,1.920~14.803 ,and 0.205~0.868 respectively ,P <0.01).

Conclusion:Among many clini-cal factors which influenced complications of renal biopsy , the independent factors were shown as follows:acute renal failure and hypertension (diastolic pressure in excess of 95mmHg) and nephritic syndrome. Acute renal failure with hypertension appeared to have an additive effect on complication rate(P<0.01).

  肾活检是当代肾脏病临床诊断和治疗不可或缺的手段[1]。近年来肾活检技术已取得重要进展[1-3]。但它作为一种有创性检查仍可能产生一些出血性损伤等穿刺并发症。如何在提高肾活检成功率的同时减少并发症的发生始终是我们面临的一个重要课题。本文目的在于通过大样本的调查和回顾性分析进一步评价超声引导自动肾活检并发症的发生几率和独立因素以期更好地指导其临床应用。

 

1 资料和方法

1.1 研究对象 病例来源为北京大学第三医院自19913月至19991511例接受自动肾活检(18G活检针) 的肾病科和儿科住院患者281230年龄8天~75平均32.8岁。其中包括血尿、蛋白尿或() 高血压等原因不明患者214例。所有病人出凝血时间正常。

1.2 超声仪器和活检针具 所用仪器为Aloka SSD-650实时超声诊断仪弧阵式探头(曲率半径为20mm),发射频率3.5MHz,配有穿刺导向专用附加装置和导针。自动活检装置(ABD)为瑞典Bard公司产品包括射程为23mmBiopsy自动活检枪以及一套与之匹配的Tru-cut式活检针。一律采用18G活检针(外径1.2mm、内径1.0mm、针槽17mm)

1.3 方法 自动活检操作按常规步骤和方法进行。全部资料均以EXCEL97建立数据库采用SAS(6.12)软件包进行统计分析。

2 结果

2.1 自动肾活检并发症的发生率 自动肾活检出现肉眼血尿15(2. 94 %),肾周或被膜下血肿23(4.50 %)。并发症共计发生38(7.44 %),均为轻度并发症未经治疗均自愈。没有重度并发症发生。
