Although a snare is the commonly used device for antegrade double J (DJ) stent removal, there are some cases in which DJ stent removal using only a snare is particularly difficult. In the present study, an unfavorable positioning of the proximal DJ stent tip and tip embeddedness were significantly associated with a simple snare technique failure; thus, present the modified snare technique to overcome the simple snare technique failure. By applying these 2 techniques together, we can increase the overall technical success rate up to 97% (196/202). The modified snare technique is safe and effective in cases of simple snare technique failure.
尽管圈套器是常用的顺行双 J（DJ）支架取出的装置，但仍有一些情况下，仅使用圈套器取出 DJ 支架特别困难。在本研究中，近端 DJ 支架尖端的不利位置和尖端嵌入与单纯圈套器技术失败显著相关；因此，提出改良的圈套器技术以克服单纯圈套器技术失败。通过联合应用这 2 种技术，我们可以将整体技术成功率提高至 97%（196/202）。在单纯圈套器技术失败的情况下，改良的圈套器技术是安全且有效的。
