The development of percutaneous renal biopsy as a routinary diagnostic procedure for renal masses is topic of discussion for the last few years. However, this technique has been associated with some complications, although infrequent, and morbidity. Our objective is to carry out a descriptive study about complications and outcomes of orthotopic kidney biopsies with 16 G needle.
A retrospective review of 180 orthotopic ultrasound-guided renal biopsies performed in our service among January 2008 to May 2010 was carried out. The procedure was developed using an automated biopsy gun (16G needle). Multiple clinical variables, early post-procedure complications and its management were collected. Complication rates as well as the relationship between risk factors and occurrence of complications were studied.
Mean age was 55.8 years. The average number of biopsy cylinders per intervention was 2.49. The overall complication rate was 5.6%. An interventionist attitude derived from complication of the procedure was necessary in only 3 patients (1.67%). No surgical interventions were required and no death as consequence of procedure was registered. No relationship between hypertension (P=.09) previous anticoagulation (P=.099) or previous antiaggregation (P=.603) and complications were demonstrated. In 2.8% of biopsies the material obtained was insufficient for diagnosing.
Percutaneous ultrasound-guided renal biopsy with 16G needle is a safe technique with high diagnostic performance.
经皮肾活检作为肾肿块常规诊断方法的发展在过去几年一直是讨论的话题。然而，尽管这种技术相关并发症并不常见，但仍存在一些并发症及发病率。我们的目的是对使用16G针进行原位肾活检的并发症和结果进行描述性研究。
对2008年1月至2010年5月在我院进行的180例超声引导下原位肾活检进行回顾性研究。该操作使用自动活检枪（16G针）进行。收集了多个临床变量、术后早期并发症及其处理情况。研究了并发症发生率以及危险因素与并发症发生之间的关系。
平均年龄为55.8岁。每次干预的活检组织平均数量为2.49个。总体并发症发生率为5.6%。仅3例患者（1.67%）因操作并发症需要采取干预措施。无需手术干预，且未记录到因操作导致的死亡。未证明高血压（P = 0.09）、既往抗凝治疗（P = 0.099）或既往抗血小板治疗（P = 0.603）与并发症之间存在关联。在2.8%的活检中，获取的材料不足以用于诊断。
使用超声引导下16G针进行经皮肾活检是一种安全且诊断性能高的技术。
