In Vitro Comparison of Prototype Magnetic Tool with Conventional Nitinol Basket for Ureteroscopic Retrieval of Stone Fragments Rendered Paramagnetic with Iron Oxide Microparticles

The Journal of Urology, 07/16/2012

The prototype magnetic tool improved the efficiency of retrieving stone particles rendered paramagnetic that were less than 2 mm but showed no advantage for larger fragments. This system has the potential to decrease the number of small retained fragments after ureteroscopic lithotripsy.
