目的：探讨超声引导下小儿经皮肾穿刺活检术的成功率和安全性，并评价肾组织病理检查在小儿肾脏疾病的临床诊治中的指导意义。方法：实时超声引导下对20例肾脏疾病患儿行经皮肾穿刺活检术，标本进行光镜、免疫荧光和电镜检查，观察术后并发症的发生。结果：本组均成功获取肾组织，取材成功率100．0％。未见严重术后并发症。结论：超声引导下经皮肾组织活检操作简单、安全可靠、成功率高、并发症少，对小儿。肾小球疾病的诊断、治疗及评估预后有重要价值，值得基层医院推广。

Pathological Type and Clinical Signification of Percutaneous Renal Biopsy in Children with Kidney Disease

Objective： To investigate the success rate and safety of percutaneous renal biopsy by ultrasound in children with kidney disease, and to study the value of renal pathological examination in clinical diagnosis and treatment of renal diseases in children. Methods： Children （20 cases） with renal disease underwent percutaneous nephrostomy renal biopsy by ultrasound. Specimens were tested for classification of pathology by light microscopy, immunofluorescence and electron microscopy. The occurrence of postoperative complications was observed. Results： Biopsies were successfully performed in the study without any complication. Conclusion： The percutaneous renal biopsy by ultrasound is convenience, safe, reliable, high success rate and less complication and has important value in diagnosis, treatment and assessment of prognosis of children with glomerular renal disease. It should be spread by primary hospitals.
