The application of a magnetic material to the removal of stones. The magnetic material constitutes the nanoparticle core, and the surface modifier monomer is connected to the nanoparticle core through the initiator and / or crosslinking agent to form the nanoparticles shell. The nanoparticles can encapsulate the stones in the ureter, and remove the remaining small stones in the body without damage when the external magnetic field is applied. When the stones are removed, they will not damage the ureteral wall and facilitate the placement of stones.
