Quantifying the Forces Needed for Ureteral Stent Removal: Initial Evaluation of Magnetic Stent Removal Devices on Benchtop and Porcine Models

Indwelling ureteral stents are commonly used in pediatric surgeries for kidney stones and urinary tract obstruction, but often require instrumentation or anesthesia for removal. We evaluated the use of novel magnet devices to remove indwelling ureteral stents with a distally attached magnetic bead. Since the forces required for stent removal are unknown, we aimed to characterize and quantify the forces required for stent removal for future prototype testing.
