A recently developed biopsy gun was used in the ultrasound (US)-guided biopsy of native kidneys in seven children. The biopsy gun employs a needle (18 gauge) smaller than that usually used for renal biopsies. In all seven cases it provided a core biopsy specimen that contained enough glomeruli to make a definitive histologic diagnosis of renal parenchymal disease. Use of the biopsy gun eliminated the more complicated movements needed to obtain samples with the conventional manual biopsy techniques. No major complications occurred, and in only one case a minor complication, trace hematuria determined by means of dipstick analysis, was found. The time required to obtain the tissue samples was decreased with use of this technique. Because of the advantages of the biopsy gun, the authors now use it exclusively in percutaneous US-guided biopsy of native pediatric kidneys and recommended that this method be considered by other institutions performing similar biopsies.
一种最近研发的活检枪被用于7名儿童的超声引导下的自体肾活检。该活检枪使用的针（18号）比通常用于肾活检的针要小。在所有7例病例中，它都提供了一份包含足够肾小球的核心活检标本，足以对肾实质疾病做出明确的组织学诊断。使用活检枪消除了采用传统手动活检技术获取样本所需的更复杂操作。未发生重大并发症，仅1例出现轻微并发症，通过试纸条分析确定为微量血尿。使用该技术获取组织样本所需的时间减少。由于活检枪具有这些优点，作者现在在儿科自体肾的经皮超声引导活检中只使用它，并建议其他进行类似活检的机构考虑采用这种方法。
