To compare stone retrieval and release from seven basket designs in vitro.
We tested two tipped and one tipless NCompass models, three other tipless Nitinol designs (NCircle, Sur-Catch, and Dimension), and the Segura Hemisphere for their ability to retrieve and release single beads 8, 6, 5.6, and 5 mm diameter and multiple beads 3.6 mm diameter in both a ureteral and a caliceal model in three separate attempts.
In the ureteral model, all baskets were successful in retrieving all sizes of single beads. With multiple 3.6-mm beads, only the NCompass and Dimension designs were able to retrieve at least two of three beads in all attempts. With the exception of the Segura Hemisphere, all designs were successful in releasing all bead sizes. In the caliceal model, only the NCircle, Dimension, and tipless NCompass models were able to retrieve all bead sizes in 100% of the trials. The tipped NCompass and Hemisphere designs were unable to retrieve any beads in this model. The Sur-Catch basket was successful in the retrieval of large beads only. The Dimension articulating design was the only basket able to release all bead sizes in all attempts. The tipless NCompass basket did not release any of the beads once engaged.
Nitinol basket designs show excellent retrieval and release capabilities in the in-vitro ureteral model. The articulating Nitinol basket has the best stone-releasing capability of all baskets tested.
在体外比较七种篮式器械的取石和释石能力。
我们测试了两种带尖端和一种无尖端的NCompass型号、其他三种无尖端的镍钛诺设计（NCircle、Sur-Catch和Dimension）以及Segura半球形篮式器械，在输尿管和肾盂模型中，分三次单独尝试，评估它们取出和释放直径为8、6、5.6和5毫米的单个珠子以及直径为3.6毫米的多个珠子的能力。
在输尿管模型中，所有篮式器械都成功取出了各种尺寸的单个珠子。对于多个3.6毫米珠子，只有NCompass和Dimension设计在所有尝试中都能取出三颗珠子中的至少两颗。除Segura半球形篮式器械外，所有设计都成功释放了所有尺寸的珠子。在肾盂模型中，只有NCircle、Dimension和无尖端的NCompass型号在100%的试验中能够取出所有尺寸的珠子。带尖端的NCompass和半球形设计在该模型中无法取出任何珠子。Sur-Catch篮式器械仅成功取出了大珠子。Dimension关节式设计是唯一一种在所有尝试中都能释放所有尺寸珠子的篮式器械。无尖端的NCompass篮式器械一旦夹住珠子就无法释放任何一颗。
镍钛诺篮式设计在体外输尿管模型中显示出出色的取石和释石能力。关节式镍钛诺篮式器械在所有测试的篮式器械中具有最佳的结石释放能力。
