Abstract:
Objective To study whether tissue injury could be increased by double shock wave while it improves the efficiency of lithotripsy. Methods A series of experiment study on the tissue injury in vivo pigs with double and single shock wave as well as electromagnetic shock wave has been carried out. Results Under the conditions of 8 kV and 1 000 times concussion, the trauma range of kidney is 18 mm?15 mm?3 mm with single shock wave,and 14 mm?11 mm?2 mm with double shock wave,the trauma range of ureter is 42 mm with single shock wave and 30 mm with double shock wave.Under the same energy and concussion,the injury focus induced by double shock wave is small than that induced by single shock wave.Microstructure pathology shows that the characteristics of focus on renal artery,vein,glumeruli,renal tubules and ureter are similar. Conclusions Compared with the focus induced by single or by electromagnetic shock wave,the focus on the tissue of kidney and ureter induced by the double shock wave is smaller.
