Purpose Of Review:
Flexible ureteroscopes have allowed us to treat renal stones endoscopically through natural orifices. Unfortunately, there continues to be the problem of remnant stone fragments that continue to pose a health problem to patients with the risk of recurrent symptoms, obstruction and infection.
Recent Findings:
This article describes the research around a novel method of stone fragment extraction using microparticles and magnets. We explore the studies related to the efficiency of stone extraction and preliminary safety data.
Summary:
This novel technique has the potential to improve the efficiency of stone fragment retrieval during retrograde intrarenal stone surgery, potentially improving stone-free rates of the surgery. Further research needs to be carried out before it is ready for human use.
