Cavitation Bubble Cluster Activity in the Breakage of Kidney Stones by Lithotripter Shockwaves
Yuri A. Pishchalnikov,Oleg A. Sapozhnikov,Michael R. Bailey,James C. Williams,Robin O. Cleveland,Tim Colonius,Lawrence A. Crum,Andrew P. Evan,James A. McAteer +8 more
TL;DR: Cavitation-mediated damage to stones is attributable, not to the action of solitary bubbles, but to the growth and collapse of bubble clusters.
Journal ArticleDOI
Air Pockets Trapped During Routine Coupling in Dry Head Lithotripsy Can Significantly Decrease the Delivery of Shock Wave Energy
Yuri A. Pishchalnikov,Joshua S. Neucks,R. Jason VonDerHaar,Irina V. Pishchalnikova,James C. Williams,James A. McAteer +5 more
TL;DR: Coupling in lithotripsy can pose a significant barrier to the transmission of shock wave energy to the patient, suggesting that repositioning the patient could substantially degrade coupling quality.
Journal ArticleDOI
Why stones break better at slow shockwave rates than at fast rates: in vitro study with a research electrohydraulic lithotripter.
Yuri A. Pishchalnikov,James A. McAteer,James C. Williams,Irina V. Pishchalnikova,R. Jason VonDerHaar +4 more
TL;DR: Cavitation bubbles do not persist between SWs, and mature bubbles from one pulse do not interfere with the next pulse, even at 120 SW/min, however, cavitation nuclei carried by fine particles released from stones can persist between pulses.
Journal ArticleDOI
CT visible internal stone structure, but not Hounsfield unit value, of calcium oxalate monohydrate (COM) calculi predicts lithotripsy fragility in vitro
Chad A. Zarse,Tariq A. Hameed,Molly E. Jackson,Yuri A. Pishchalnikov,James E. Lingeman,James A. McAteer,James C. Williams +6 more
TL;DR: It is stone morphology, rather than X-ray attenuation, which correlates with fragility to SW’s in this common stone type, and suggests that stone fragility in patients could be predicted using pre-treatment CT imaging.
Journal ArticleDOI
Cavitation detection during shock-wave lithotripsy.
Michael R. Bailey,Yuri A. Pishchalnikov,Oleg A. Sapozhnikov,Robin O. Cleveland,James A. McAteer,Nathan Miller,Irina V. Pishchalnikova,Bret A. Connors,Lawrence A. Crum,Andrew P. Evan +9 more
TL;DR: The finding that cavitation occurs in kidney tissue is a critical step toward determining the mechanisms of tissue injury in SWL.
