Evaluation of pain perception associated with use of the magnetic-end ureteric double-J stent for short-term ureteric stenting

Purpose To investigate the morbidity, complication rate, and pain perception during removal of a novel ureteric stent with a magnetic end using a-traumatic retrieval catheter. Methods Between November 2013 and July 2015, 151 consecutive patients who underwent semirigid ureterorenoscopy (URS) for stone removal were prospectively enrolled. Stent removal was performed under local anesthesia using a special magnetic-end stent remover 1 week following URS. At follow-up, we obtained patients’ medical history, urine culture result, renal ultrasonogram, and visual analog scale (VAS) score regarding stent irritation (VAS 1) and pain during removal (VAS 2). Results Pain perception during stent removal was significantly less painful in patients with a magnet stent than in those with a regular stent ( p
