Two techniques for renal allograft biopsy were retrospectively evaluated to compare relative safety and efficacy. After ultrasound (US) localization of the kidney and biopsy with a hand-held 14-gauge cutting needle, an adequate specimen was obtained in 74 of 77 cases (96%). Major complications occurred in six of these 77 cases (8%). One hundred four biopsies were performed by using a smaller 18-gauge cutting needle with a spring-loaded biopsy "gun" and real-time US guidance. With this newer technique, specimens adequate for diagnosis were obtained in 99 biopsies (95%). There was a single major complication with this technique (1%). The 18-gauge needle with real-time US guidance yields comparably adequate specimens with a lower frequency of complications.
对两种肾移植活检技术进行回顾性评估，以比较其相对安全性和有效性。在超声（US）定位肾脏并用手持14号切割针进行活检后，77例中有74例（96%）获得了足够的标本。这77例中有6例（8%）发生了严重并发症。使用较小的18号切割针和弹簧加载活检“枪”并在实时超声引导下进行了104次活检。采用这种更新的技术，99次活检（95%）获得了足以用于诊断的标本。该技术有1例严重并发症（1%）。实时超声引导下的18号针能获得相当充足的标本，且并发症发生率较低。
