Abstract: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.
