A study of stone fragmentation in shock wave lithotripsy by customizing the acoustic field and waveform shape
Shock wave lithotripsy is the preferred treatment modality for kidney stones in the United States. Despite clinical use for over twenty-five years, the mechanisms of stone fragmentation are still under debate. A piezoelectric array was employed to examine the effect of waveform shape and pressure …

Adaptable Design Improvements For Electromagnetic Shock Wave Lithotripters And Techniques For Controlling Cavitation
… garner better mechanistic understanding of how shock wave lithotripsy (SWL) breaks stones in order to guide design improvements to a modern electromagnetic (EM) shock wave lithotripter. To accomplish this goal, experimental studies were carefully designed to isolate mechanisms of fragmentation, …

Ureteroskopijos ir ekstrkorporinės litotripsijos efektyvumo bei rizikos veiksnių palyginimasis tyrimas šalinant akmenis iš viršutinio šlapimtakio trečdalio /
… effectiveness of ureteroscopy and extracorporeal lithotripsy application. The study results showed that comparing with extracorporeal lithotripsy, ureteroscopy with a laser lithotripsy is a more effective and quicker treatment method when seeking to reach a stone free rate in the upper part of the …
