经皮肾穿刺活检在急性肾功能衰竭诊治中的地位

目的探讨急性肾功能衰竭（ARF）患者的病理类型及病因分布,评价肾活检在肾脏病诊治中的作用与地位。方法对30例ARF具有肾穿刺活检适应证的患者,在B超介入定位下行经皮肾穿刺活检,并做光镜、免疫病理检查及结合临床特点进行分析。结果 30例ARF患者肾穿刺均能成功取得肾小球,标本合格率为97%,病理分析显示：硬化性肾炎2例（6.67%）;原发性肾小球肾炎17例（56.67%）,其中IgA肾病3例,肾小球轻微病变5例,膜性肾病2例,局灶节段性硬化性肾炎2例,毛细血管内增生性肾炎2例,新月体肾炎3例;继发性肾小球肾炎8例（26.62%）,其中狼疮性肾炎6例,过敏性紫癜肾炎2例;急性肾小管坏死2例（6.67%）;急性间质性肾炎1例（3.33%）。并发症主要有肉眼血尿2例,肾周血肿1例,未发生误穿其他脏器、感染及严重大出血等并发症。结论对ARF患者行肾活检检查有助于明确病因及病理类型,对指导治疗及判断预后均有非常重要的作用。
