Objective. To demonstrate the advantage of our newly designed magnetic ureteric stenting retrieval device over traditional nonmagnetic ureteric stents and other retrieval devices without cystoscopy intervention on clinical application and cost-related outcomes. Patients and Methods. A total of 333 patients were recruited into two study groups: magnetic-end ureteral stent (Group A) and conventional ureteral stent (Group B). The effects were evaluated by Ureteral Stent Symptom Questionnaire (USSQ) scores, complications of the indwelling stent, visual analog scale (VAS) pain scores at stent removal, and cost-analysis outcomes between the magnetic ureteric stenting retrieval device and traditional double-J ureteral stent (DJUS) removed by cystoscopy. Results. The VAS of the pain score of patients undergoing magnetic stent removal with the retrieval device was 2 ± 0.97, whereas that of patients undergoing conventional ureteral stent removal with cystoscopy was 5.76 ± 1.53 (p
