In addition to currently available modalities of intracorporeal lithotripsy (ultrasonic, electrohydraulic, and laser), a new ballistic lithotriptor known as the Swiss Lithoclast has recently gained attention. This study reports our experience with the Swiss Lithoclast in the endoscopic management of urinary calculi.
A total of 51 patients with urinary calculi were treated with the Swiss Lithoclast; one patient with a renal calculus, 28 with ureteral calculi, and 22 with lower urinary tract (bladder, urethra and Kock pouch) calculi.
The Lithoclast successfully fragmented 94% of the calculi, independent of stone composition. Complete failure of fragmentation was not encountered. In six of the 10 upper ureteral calculi, stone fragments were pushed up into the calyces. Adjunctive extracorporeal shock wave lithotripsy for residual fragments was performed in six cases. The stone-free rate at one and three months was 84% and 88%, respectively. There were no intraoperative or long-term complications directly related to the use of this device.
The Swiss Lithoclast is a safe and effective means of intracorporeal lithotripsy. Although suitable for mid and lower ureteral stones, the device has a risk of stone push-up in patients with upper ureteral stones.
除了目前可用的体内碎石方法（超声、液电和激光）外，一种名为瑞士碎石机的新型弹道碎石器最近受到了关注。本研究报告了我们使用瑞士碎石机进行尿路结石内镜治疗的经验。
共有51例尿路结石患者接受了瑞士碎石机治疗；1例肾结石患者，28例输尿管结石患者，22例下尿路（膀胱、尿道和科克袋）结石患者。
无论结石成分如何，碎石机成功粉碎了94%的结石。未出现完全粉碎失败的情况。在10例上段输尿管结石中的6例中，结石碎片被向上推入肾盏。6例患者对残留碎片进行了辅助体外冲击波碎石治疗。1个月和3个月时的无石率分别为84%和88%。没有与使用该设备直接相关的术中或长期并发症。
瑞士碎石机是一种安全有效的体内碎石方法。虽然适用于输尿管中下段结石，但该设备对上段输尿管结石患者有结石上推的风险。
