Abstract
Urolithiasis is an increasing problem in our society. Current methods of treatment often leave behind small stone fragments that act as a nidus for further stone formation requiring secondary treatments.
Ferromagnetics offers a novel approach for the extraction of small stone fragments during flexible ureteroscopy or percutaneous nephrolithotomy. As a proof of concept, it has been shown to be more efficient compared to a standard 2.4 F nitinol tipless basket for stones smaller than 3 mm in in vitro experiments.
Further, investigations will need to be carried out to determine biocompatibility and to improve the magnetic properties of the microparticles and the tools used for magnetic extraction.
