We modeled retropulsion during holmium:YAG lithotripsy on the conservation of momentum, whereby the force of ejected fragment debris off of the calculous surface should equal the force of retropulsion displacing the stone. We tested the hypothesis that retropulsion occurs as a result of ejected ...
To test the hypothesis that holmium:yttrium-aluminum-garnet (YAG) lithotripsy efficiency varies with stone composition. Methods. Single pulses of holmium:YAG energy were delivered using 272-, 365-, 550-, and 940-μm optical fibers to human calculi composed of calcium oxalate monohydrate (COM), ...
Results: The Ho:YAG laser fragmented all types of calculi. Of 38 patients, 29 (76%) with ureteric stones were stone-free and 7 (18%) had stone fragments smaller than 2 mm left 1-3 months after the lithotripsy, resulting in a total clinical success rate of 95%. The procedure caused ...
