Automatic renal biopsy device under Truguide needle guided were performed on 178 patients with nephropathy, Renal biopsies were successfully performed totally, and mean numbers of glomerulus were ( 18. 0 ± 1.1) per patient. And there was no prominent incidence of complications. The method has the advantages in easy manipulation, higher successful rate and lower incidence of complications.%在B超实时定位下,使用同轴穿刺引导针对178例患者肾脏穿刺活检,穿刺顺利,平均肾小球(18.0±7.7)个,全部获得成功,无明显并发症.结果 表明在超声实时定位下,使用同轴穿刺引导针行经皮肾穿刺活检是一种安全、有效的方法.
