We evaluated the efficacy of endoscopic pneumatic lithotripsy with the Lithoclast for urinary tract calculi. The use of this stone disintegration system and the possible complications are described.
We performed a retrospective analysis of the results achieved in the first 100 patients (156 stones) that had been treated with this system at different sites. The patients were evaluated radiologically early postoperatively and throughout follow up (mean 12 months).
Stone fragmentation could not be achieved in three patients, the only failures. The early postoperative assessment showed residual stones in 13% of the patients; 5 patients spontaneously passed the stone remnants and 8% had stone remnants on radiological evaluation during follow up. The only remarkable complication was a perforated ureter which required no surgery.
In our experience, the Lithoclast lithotripsy system is effective at any level of the urinary tract. It has a low complication rate and is simple and low-cost.
我们评估了使用碎石钳进行内镜气压弹道碎石术治疗尿路结石的疗效。描述了该结石破碎系统的使用情况及可能出现的并发症。
我们对在不同地点接受该系统治疗的前100例患者（156颗结石）的治疗结果进行了回顾性分析。术后早期及整个随访期间（平均12个月）对患者进行影像学评估。
3例患者未能实现结石破碎，为仅有的失败病例。术后早期评估显示，13%的患者有残余结石；5例患者结石残余物自行排出，随访期间影像学评估发现8%的患者有结石残余物。唯一显著的并发症是输尿管穿孔，无需手术治疗。
根据我们的经验，碎石钳碎石系统在尿路的任何部位均有效。它并发症发生率低，操作简单且成本低廉。
