我们的目的是评价使用带14号针的自动活检装置（活检枪）进行超声引导肾活检的安全性和诊断有效性。回顾性分析了在两所大型大学医院进行的515例连续超声引导肾活检。345例肾移植患者和170例自体肾患者进行了活检。95.3%的病例（移植肾组94.8%，自体肾组96.5%）的组织标本足以进行组织学评价。总体并发症发生率为12.2%，自体肾组（19.4%）明显高于肾移植组（8.7%）。严重并发症发生在2.7%的病例中（2.9%的肾移植物和2.4%的自体肾活检），包括1例手术相关死亡和2例其他患者的肾移植物丢失。在9.5%的活检中观察到轻微并发症，自体肾组（17.1%）明显多于移植肾组（5.8%）。使用14号针头的自动设备进行肾活检具有较高的组织回收率，但严重并发症的风险较小。
Our objective was to evaluate the safety and diagnostic efficacy of the ultrasound-guided renal biopsy procedure using an automated biopsy device (Biopty gun) with a 14-gauge needle. Five hundred fifteen consecutive ultrasound-guided renal biopsies performed in two large university hospitals were retrospectively reviewed. Three hundred forty-five biopsies were performed on renal allografts and 170 on native kidneys. The tissue specimen was adequate for histological evaluation in 95.3% of the cases (94.8% in the transplanted kidney group, 96.5% in the native kidney group). The overall complication rate was 12.2% and was significantly higher in the native kidney group (19.4%) than in the renal allograft group (8.7%). Major complications occurred in 2.7% of the cases (2.9% of the renal allografts and 2.4% of the native kidney biopsies), including one procedure-related death and the loss of the renal allograft in two other patients. Minor complications were noted in 9.5% of the biopsies and there were significantly more in the group of the native kidneys (17.1%) than in the group of the transplanted kidneys (5.8%). Renal biopsy with an automated device using a 14-gauge needle has a high tissue recovery rate, but it is associated with a small risk of serious complications.
