Polymer–Mineral Composites Mimic Human Kidney Stones in Laser Lithotripsy Experiments

, 2019
Despite the widespread use of laser lithotripsy to fragment kidney stones in vivo, there is a lack of robust artificial stone models to replicate the behavior of human stones during lithotripsy procedures.

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion

Advanced Science, Volume 13, Issue 22, 17 April 2026.
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.

Single-operator holmium laser lithotripsy under direct peroral cholangioscopy using an ultra-slim upper endoscope in a patient with a large stone in the common bile duct

The Turkish Journal of Gastroenterology, 2017
In patients with complicated stones (e.g., large stones) in the common bile duct (CBD), advanced treatment modalities are generally needed. Here we present an interesting case of a large CBD stone treated with holmium laser lithotripsy, which was ...

Rise in intraluminal temperature during ureteroscopy: Is this a concern? [PDF]

Investigative and Clinical Urology
The global increase in urolithiasis prevalence has led to a shift towards minimally invasive procedures, such as retrograde intrarenal surgery, supported by advancements in laser technologies for lithotripsy.

Concomitant catheter drainage alleviates the thermal effect of holmium lasers during ureteroscopic lithotripsy: a retrospective cohort study

BMC Urology
Background Thermal control is pivotal for preventing ureter thermal injury during laser lithotripsy; however, patient-based studies have rarely addressed this topic. In recent years, we have employed a ureter catheter for irrigation drainage and measured

Renal rupture with perirenal hematoma after ureterorenoscopic holmium:YAG laser lithotripsy for a renal pelvic stone

, 2013
We present a rare, but critical case of renal rupture after ureterorenoscopic holmium:YAG laser lithotripsy. This is the first case report of renal rupture after laser lithotripsy in managing an upper urinary tract stone.
