Patients with large bladder stones are often difficult to treat endoscopically with the current modalities available to the practicing urologist. We present the results of cystolithotripsy of bladder stones larger than 4 cm with the holmium: Yag (Ho:Yag) laser. In our three patients, all patients were rendered stone free without complication using the Ho:Yag laser, with an average anesthesia time of 50 min. Minimal tissue trauma or stone movement were observed. All stones were easily fragmented, even one stone that had previously been refractory to electrohydraulic lithotripsy. Our conclusion is that the Ho:Yag laser is a safe and effective treatment for patients with large bladder stones. Its use may make it possible to eradicate stones endoscopically that otherwise would require open surgery.
对于患有大膀胱结石的患者，泌尿外科医生目前可用的治疗方式往往难以通过内镜进行治疗。我们展示了使用钬激光（Ho:Yag）对大于4厘米的膀胱结石进行膀胱碎石术的结果。在我们的三名患者中，使用Ho:Yag激光使所有患者结石清除且无并发症，平均麻醉时间为50分钟。观察到组织创伤极小或结石移动。所有结石都很容易破碎，甚至包括一块先前对液电碎石术难治的结石。我们的结论是，Ho:Yag激光对于患有大膀胱结石的患者是一种安全有效的治疗方法。其使用可能使通过内镜根除结石成为可能，否则这些结石将需要进行开放手术。
