Assess glomerular yield and safety profile of two different types of needles for percutaneous ultrasound-guided kidney biopsy.
Over 24 months, 121 ultrasonographic ultrasound-guided renal biopsies were performed on native kidneys of 121 adults: 66 with 16-gauge, 29-mm end-cut (BioPince) needles and 55 with 14-gauge, 1.9-mm side-notch (Tru-Cut) needles.
The mean number of complete glomeruli harvested per biopsy was 21.0 and 19.3, respectively, and the mean number of core samples required to obtain a satisfactory biopsy was 1.8 and 2.6, respectively. The ratio of glomeruli harvested to core samples needed with the end-cut needle was 58% greater than that with the side-notch needles (11.7 vs 7.4, respectively; difference of 4.3; 95% confidence interval: 2.0, 6.8). Procedures performed with end-cut needles were associated with fewer major complications (1.5% vs 7.3% with side-notch needles).
Compared to the 14-g Tru-cut needle, the 16-g end-cut needle provided better glomerular yield per core sample, required fewer cores for satisfactory tissue specimen, and resulted in fewer major complications.
评估两种不同类型的针在经皮超声引导下肾脏活检中的肾小球产量和安全性。
在 24 个月内，对 121 例成人的 121 例原发性肾脏进行了超声引导下的肾脏活检：66 例使用 16 号、29 毫米端切（BioPince）针，55 例使用 14 号、1.9 毫米侧切（Tru-Cut）针。
每例活检获得的完整肾小球数分别为 21.0 和 19.3，获得满意活检所需的核心样本数分别为 1.8 和 2.6。端切针获得的肾小球数与侧切针所需的核心样本数之比分别为 58%（分别为 11.7 和 7.4，差异为 4.3；95%置信区间：2.0，6.8）。使用端切针进行的操作与较少的主要并发症相关（分别为 1.5%和 7.3%使用侧切针）。
与 14 号 Tru-cut 针相比，16 号端切针在每个核心样本中提供了更好的肾小球产量，需要更少的核心样本获得满意的组织标本，并且导致更少的主要并发症。
