Poor expansion of a spiral stone basket within the ureter often results in failure to engage a ureteral calculus. A special pull-wire incorporated into the design of such a basket facilitates predictable expansion of the basket even when the ureteral lumen seems narrow. Excellent results in capturing and removing ureteral calculi have been achieved with this controllable basket, including stones in several patients in whom standard spiral baskets failed to engage the calculus.
输尿管内螺旋形结石篮扩张不佳常常导致无法套住输尿管结石。这种结石篮设计中内置的特殊拉线即使在输尿管管腔看起来狭窄时也有助于使结石篮可预测地扩张。使用这种可控制的结石篮在捕获和取出输尿管结石方面取得了优异的效果，包括在几名患者中，标准螺旋形结石篮未能套住结石的情况。
