Bubble Dynamics in Laser Lithotripsy [PDF]
Journal of Physics: Conference Series, 2015 Laser lithotripsy is a medical procedure for fragmentation of urinary stones with a fiber guided laser pulse of several hundred microseconds long. Using high-speed photography, we present an in-vitro study of bubble dynamics and stone motion induced by Ho:YAG laser lithotripsy.

Numerical simulations of non-spherical bubble collapse [PDF]
, 2009 A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...

Thermal effect of holmium laser during ureteroscopic lithotripsy
BMC Urology, 2020 Background Holmium laser lithotripsy is the most common technique for the management of ureteral stone. Studies founded that holmium laser firing can produce heat which will cause thermal injury towards ureter.
