钬激光治疗输尿管结石123例

Holmium laser lithotrity therapeutic report in 123 cases with ureteral calculi

目的：探讨应用钬激光碎石术治疗输尿管结石的有效性及安全性。方法：总结输尿管镜下钬激光治疗123例输尿管结石患者的临床资料。结石直径0．5～2．0cm，平均1．1cm。结果：123例输尿管结石患者一次手术取尽率为86．2％（106例），有9例结石完整进入肾内，8例因结石之下输尿管严重扭曲改其他术式。平均手术时间和术后住院天数分别为55min及4d。结论：对于直径〈2cm、结石处炎症肉芽组织多、结石下段无明显梗阻的输尿管结石，输尿管镜下钬激光碎石治疗仍是最好的选择。

Objective： To observe clinical effectivity and safety of holmium laser lithotrity on ureteral calculi. Methods： 123 patients with ureteral calculus were treated with Vensapulse Select holmium laser lithotrity through urethra under ureteroscopy. The diameter of calculus was 0.5-2.0 cm, average 1.1 cm. Results. The grinding rate of calculus after one lithotrity was 83.5%, of 9 cases calculus run in kidney, other 8 cases were subject to surgery due to renal duct severe twist under calculus. The average operating time was 55 minutes; postoperative hospital stay was 4 days. Conclusion： holmium laser lithotrity is an optimal way in patient with ureteral calculus that diameter in 2 cm, more inflammatory granulation tissue around calculus and no manifest obstruct under calculus.
