Between 1996 and 1997, 2,045 percutaneous renal biopsies were performed on native kidneys in 2,013 patients in pediatric nephrology units in Japan. Of these, 50.8% were performed by automated needle biopsy gun under ultrasound guidance, and the standard biopsy needle, Tru-cut needle or Vim-Silverman needle, under fluoroscopic guidance was used in 12.4% and 12.3% of the biopsies, respectively. Adequate renal tissue for histological diagnosis was obtained in 98.7% of cases, and the success rates for the techniques were not significantly different. The overall complication rate was 5.8%; gross hematuria occurred in 2.7% and large perirenal hematoma in 0.9% of cases. These complication rates were higher when a standard needle under fluoroscopic guidance was used compared with an automated needle under ultrasound guidance. We conclude that pediatric nephrologists in Japan perform percutaneous renal biopsies safely, partly due to technical improvements, such as the automated needle or ultrasound guidance.
1996年至1997年间，日本儿科肾脏病科对2013例患者的自体肾进行了2045次经皮肾活检。其中，50.8%是在超声引导下使用自动活检针进行的，分别有12.4%和12.3%的活检是在透视引导下使用标准活检针（Tru-cut针或Vim-Silverman针）进行的。98.7%的病例获得了足够用于组织学诊断的肾组织，且这些技术的成功率无显著差异。总体并发症发生率为5.8%；2.7%的病例出现肉眼血尿，0.9%的病例出现肾周大血肿。与超声引导下的自动活检针相比，透视引导下使用标准活检针时这些并发症发生率更高。我们得出结论，日本的儿科肾脏病医生能够安全地进行经皮肾活检，部分原因是技术改进，如自动活检针或超声引导。
