To evaluate the effectiveness of cystoscopic lithotripsy, we performed Amplatz sheath technique using Ho: YAG laser. Maheshwari first reported the use of an Amplatz sheath in the female urethra in 1998, and Okeke et al reported the use of an Amplatz sheath for male patients during cystolithotripsy in 2004. The usefulness of the holmium (Ho): yttrium aluminum garnet (YAG) laser lithotripsy is widely accepted, even for large bladder calculi. Since then, there have been no more reports of using the sheath with an Ho: YAG laser.
We inserted the Amplatz sheath conversely. Because of the clear visualization, we used higher laser settings with 2.5 J × 15 to 20 Hz.
We experienced 3 female patients that were successfully treated with the Amplatz sheath technique using Ho: YAG laser lithotripsy. In these 3 patients, whose stone burdens were 4.5, 3.8, and 4.3 cm, they were able to successfully become stone-free with surgeries of 74 minutes, 67 minutes, and 58 minutes, respectively, with no complications.

为了评估经膀胱镜碎石术的效果，我们使用钬：钇铝石榴石（Ho：YAG）激光进行 Amplatz 鞘技术。Maheshwari 于 1998 年首次报道了在女性尿道中使用 Amplatz 鞘，而 Okeke 等人于 2004 年报道了在男性患者行膀胱结石碎石术中使用 Amplatz 鞘。钬（Ho）：钇铝石榴石（YAG）激光碎石术的有效性已被广泛接受，即使是对于较大的膀胱结石也是如此。从那时起，就没有再报道使用 Ho：YAG 激光的鞘了。
我们反插 Amplatz 鞘。由于可视化效果清晰，我们使用更高的激光设置，即 2.5 J×15 至 20 Hz。
我们成功地治疗了 3 名女性患者，她们均采用 Ho：YAG 激光碎石术的 Amplatz 鞘技术治疗。在这 3 名患者中，结石负荷分别为 4.5、3.8 和 4.3 厘米，手术时间分别为 74 分钟、67 分钟和 58 分钟，均成功达到无结石状态，且无并发症发生。
