Percutaneous renal biopsy is a fundamental diagnostic technique. Technical innovations had resulted in an increasing simplicity and safety of the procedure. In this study, 28 kidney biopsies were done using gauge 16 or 18 automated biopsy needle by inexperienced trainees, and patients were allowed full ambulation four hours after biopsy. The trainees failed in 3 (10.7%) attempts. Adequate biopsy was obtained in 89.3%, the mean number of attempts were 2.5 +/- 1.1 (range 1-6/biopsy). The mean length of specimen was 1.5 cm +/- 0.6 (range 0.4-3 cm) and the mean number of glomeruli was 12.8 +/- 7 (range 12-30 glomeruli). Immediately and twenty-four hours after kidney biopsy patients showed no evidence of gross haematuria and ultrasound did not reveal any intrarenal and perirenal haematoma. Microscopic haematuria occurred in 20 (71.4%) patients on the first day and in only 7 (25%) patients the following day. Pain had occurred in 8 (28.5%) patients post-biopsy and in 4 (14.2%) patients on the second day.
经皮肾活检是一项基本的诊断技术。技术创新使得该操作日益简便和安全。在本研究中，由缺乏经验的实习生使用16号或18号自动活检针进行了28例肾脏活检，活检后4小时允许患者自由活动。实习生有3次（10.7%）穿刺失败。89.3%的患者获得了足够的活检组织，平均穿刺次数为2.5±1.1次（范围为每次活检1 - 6次）。标本的平均长度为1.5 cm±0.6 cm（范围为0.4 - 3 cm），平均肾小球数量为12.8±7个（范围为12 - 30个肾小球）。肾活检后即刻及24小时，患者均无肉眼血尿迹象，超声检查未发现任何肾内及肾周血肿。20例（71.4%）患者在第一天出现镜下血尿，第二天仅有7例（25%）患者出现镜下血尿。8例（28.5%）患者在活检后出现疼痛，4例（14.2%）患者在第二天出现疼痛。
