To compare 18-gauge-needle automated biopsy guns to 14-gauge systems for diagnostic efficacy and safety in percutaneous renal biopsy.
One hundred sixty-one computed tomographic (CT) guided biopsies for diffuse renal disease were retrospectively reviewed. An automated biopsy gun with an 18-gauge needle was used in 74 procedures, and a 14-gauge needle was used in 87 cases.
Adequate tissue for histologic diagnosis was obtained in 96% (71 of 74) of cases with use of the 18-gauge needle, compared with 99% (86 of 87) in the 14-gauge group. The mean glomeruli per specimen were 10.7 and 13.7, respectively. Major hemorrhagic complications occurred in two cases (2.7%) of the 18-gauge group and in three cases (3.4%) of the 14-gauge group.
The use of a biopsy gun with an 18-gauge needle provides high tissue recovery rate, comparable to that with the 14-gauge system. The complication rate was acceptably low, with no statistically significant difference from the 14-gauge needles (P = .80).
比较18号针自动活检枪与14号系统在经皮肾活检中的诊断效能和安全性。
回顾性分析161例计算机断层扫描（CT）引导下针对弥漫性肾病的活检。74例操作使用了18号针自动活检枪，87例使用了14号针。
使用18号针的病例中，96%（74例中的71例）获得了足够用于组织学诊断的组织，14号针组为99%（87例中的86例）。每个标本的平均肾小球数分别为10.7和13.7。18号针组有2例（2.7%）发生严重出血并发症，14号针组有3例（3.4%）。
使用18号针活检枪的组织回收率高，与14号系统相当。并发症发生率低至可接受水平，与14号针无统计学显著差异（P = 0.80）。
