Over the last few years spring-driven mechanical biopsy guns have been introduced for performing renal biopsies. There has been little research done comparing these guns with traditional hand-driven needles in performing biopsies of native kidneys. We wished to compare our experience with the two needle types. We studied retrospectively the results and complication rates of 155 native kidney biopsies. Sixty-nine were performed with hand-driven 14-gauge needles and eighty-six with 18-gauge, spring-driven biopsy guns. Sufficient tissue for diagnosis was obtained in 96% of cases in the hand-driven group compared with 99% in the biopsy gun group (P = NS). Complications occurred in six cases in the hand-driven group compared with one case in the biopsy gun group (P = 0.02). As expected, the reported number of glomeruli per core in the 14-gauge cores was greater than in the 18-gauge cores (16.5 v 6.2, P < 0.01). This was partially offset by the greater number of passes made with the smaller needle. We conclude that similar results can be expected from both biopsy methods, with a possible slight decrease in complications using biopsy guns with smaller needle diameters.
在过去几年中，已引入弹簧驱动的机械活检枪用于进行肾活检。在对天然肾进行活检时，将这些活检枪与传统手动针进行比较的研究很少。我们希望比较我们使用这两种针的经验。我们回顾性研究了155例天然肾活检的结果和并发症发生率。69例使用手动14号针进行，86例使用18号弹簧驱动活检枪进行。手动组96%的病例获得了足够用于诊断的组织，而活检枪组为99%（P=无显著性差异）。手动组有6例发生并发症，活检枪组有1例（P=0.02）。正如预期的那样，14号针芯每芯报告的肾小球数量多于18号针芯（16.5对6.2，P<0.01）。较小针穿刺次数较多在一定程度上抵消了这一差异。我们得出结论，两种活检方法都能获得相似的结果，使用较小直径针的活检枪可能会使并发症略有减少。
