The previous methods to biopsy renal allografts at our institution involved the use of the Franklin-Silverman or Tru-Cut needles. Unfortunately they had a significant rate of post biopsy bleeding secondary to deep penetration when excess force was used to penetrate a tough transplant capsule. Although spring loaded biopsy devices have been widely used for native kidney biopsies over the past three years, the complication rate for renal allograft biopsies has not been sufficiently evaluated. We describe our experience using a disposable spring loaded biopsy device on transplanted renal grafts. Fifty-four biopsies were performed with the device, all under ultrasound guidance. The ASAP automatic biopsy system by Medi-tech was used comprising of a spring loaded gun with a 15 cm long 15 GA needle echogenic tip and 17 mm specimen notch. All patients were ultrasounded immediately post biopsy to look for hematomas. Compared to 55 previous biopsies performed using Tru-Cut needles, we conclude that the ASAP automated biopsy system proved equally effective in obtaining adequate tissue for diagnosis with fewer post-biopsy hematomas compared to traditional biopsy methods.
我们机构之前对肾移植进行活检的方法包括使用富兰克林 - 西尔弗曼针或Tru - Cut针。不幸的是，当使用过大的力穿透坚韧的移植包膜时，由于穿刺过深，这些方法导致活检后出血的发生率很高。尽管在过去三年中，弹簧加载活检装置已广泛用于自体肾活检，但肾移植活检的并发症发生率尚未得到充分评估。我们描述了我们在移植肾移植物上使用一次性弹簧加载活检装置的经验。使用该装置进行了54次活检，均在超声引导下进行。使用的是Medi - tech公司的ASAP自动活检系统，包括一支带有15厘米长、15号针、回声尖端和17毫米标本切口的弹簧加载枪。所有患者在活检后立即进行超声检查以寻找血肿。与之前使用Tru - Cut针进行的55次活检相比，我们得出结论，与传统活检方法相比，ASAP自动活检系统在获取足够组织用于诊断方面同样有效，且活检后血肿较少。
