超声引导下肾脏穿刺技术的临床应用

目的观察超声引导下穿刺取肾脏活组织的取材成功率、并发症的发生率，评价其对临床诊断的价值。方法62例肾疾病患者采用Phlipls—iE33彩色超声诊断仪，在带穿刺导向的线阵探头指引下用自动活检针快速肾活体组织取材，取材分别送检病理光镜、电镜及免疫荧光。结果62例全部穿刺成功，2例因取材不足无法做出病理诊断，60例均取得正确临床病理诊断，占96．7％。62例患者肾穿刺活检术后出现并发症3例，其中肉眼血尿2例（3．2％），肾周血肿1例（1．6％）。结论超声引导下经皮肾穿刺活检是一种安全有效的方法，成功率高，并发症少。

Clinical value of ultrasound - guided percutaneous renal biopsy

Objective To observe the achievement ratio of automatic biopsy and complication rate of ultrasound - guided automatic biopsy technique in renal disease, and to evaluate the method of pereutaneous renal biopsy for clinical diagnosis. Methods The clinical and pathological datas of 62 patients who were received renal biopsy were collected. Results All cases were successfully punctured. Two cases were fail to obtain right pathological diagnosis because the tissue was not sufficient for pathology. Biopsy -related complications occurred in 3 patients（4.8% ） ,including gross hematuria in 2 patient （3.2%） and perirenal hematoma in 1 patients（ 1.6% ）. Conclusions We conclude that ultrasound - guided percutaneous renal biopsy technique in renal disease is an useful and effective diagnostic tool, not only safe but also accurate.
