an alternative loop snare technique with many loops using a simple guide-wire for removal of a double j stent: a case series

Background: removal of a double j (dj) stent has been conventionally performed with conventional snare wires, tissue forceps, or stone baskets under fluoroscopic guidance. however, if the lumen is collapsed, is very wide, or if the tip of the dj stent is lodged in the bladder wall, the procedure becomes difficult. patients and methods: we retrospectively reviewed four patients who had undergone retrieval or replacement of their dj stents by interventional radiologists with an alternative loop snare technique using a guidewire after conventional attempts using a snare catheter had failed. results: five dj stents were completely removed without any complications. conclusion: the loop snare technique using a guidewire could be an alternative and inexpensive approach for difficult dj stent removal.
