What this research studies

I would see a new imaging system that captures fast, tiny bubbles produced during laser stone treatment so surgeons can watch what is happening in real time. The team plans to use high-resolution, 3D imaging methods to map cavitation (bubble) activity that helps break stones during ureteroscopic laser lithotripsy. The approach aims to compare different laser settings and visualize which ones produce the best stone 'dusting' while minimizing extra damage. If successful, the tool could be used during procedures to guide choices about laser power and timing.

Who could benefit from this research

Good fit: People with kidney or ureteral stones who are candidates for ureteroscopic laser lithotripsy would be the ideal participants.

Not a fit: Patients whose stones are treated without laser lithotripsy (for example, managed medically or treated with shockwave lithotripsy) would not directly benefit from this technology.

Why it matters

Potential benefit: If successful, this could make laser stone treatments faster, more effective, and reduce the need for extra procedures or instruments.

How similar studies have performed: Laboratory and imaging studies have shown cavitation affects stone breaking and some ultrasound methods have promise, but real-time 3D super-resolution cavitation mapping is a new approach that has not yet been widely tested in patients.
