Abstract
An Nd-YAG laser of 1064-nm wavelength, 8-nanosecond pulse duration, and single-pulse energy of 20 to 80 mJ can create shock waves with a peak pressure of 1000 bar in less than 4 nanoseconds. The safety of this laser has been demonstrated in cultured cells, whole blood, and porcine urothelium. Clinically, ureteral calculi have been removed from 24 of 27 patients.
摘要
一台波长为1064纳米、脉冲持续时间为8纳秒、单脉冲能量为20至80毫焦的钕钇铝石榴石激光，可在不到4纳秒的时间内产生峰值压力为1000巴的冲击波。这种激光的安全性已在培养细胞、全血和猪膀胱上皮中得到证实。临床上，27例患者中有24例的输尿管结石已被清除。
