In this series, 35 patients with medical renal disease had renal biopsy guided by computed tomography (CT). Biopsies were done by a coaxial technique in which a thin-walled 16 guage guide needle is placed adjacent to the renal capsule of the lower pole. An 18 gauge cutting needle is then placed through the guide needle, and multiple samples (2 to 4) are obtained with an automated biopsy gun. Adequacy of specimens is immediately checked in the CT suite using low-power microscopy. Specimens are submitted for light, electron, and immunofluorescence microscopy. Adequate tissue for definite diagnosis was obtained in 33 of the 35 patients (94%). One patient had moderate postbiopsy bleeding and was hospitalized. There were no major complications. CT-guided renal biopsy using a coaxial technique and automated biopsy gun is an effective means of obtaining tissue for the evaluation of medical renal disease.
在该系列研究中，35例患有内科性肾病的患者接受了计算机断层扫描（CT）引导下的肾活检。活检采用同轴技术进行，即在肾下极肾包膜旁放置一根16号薄壁引导针。然后将一根18号切割针经引导针置入，使用自动活检枪获取多个样本（2至4个）。在CT检查室使用低倍显微镜立即检查标本是否足够。标本送做光镜、电镜和免疫荧光显微镜检查。35例患者中有33例（94%）获得了足以明确诊断的组织。1例患者活检后出现中度出血并住院。无重大并发症。采用同轴技术和自动活检枪进行CT引导下肾活检是获取组织以评估内科性肾病的有效方法。
