摘要
目的评估输尿管软镜联合钬激光碎石术治疗肾结石患者的有效性及安全性,同时分别比较其用于治疗≤20mm,20～40mm和≥40mm结石时的有效性及安全性。方法收集了于2011年8月至2014年10月期间就诊于本中心的291例接受输尿管软镜联合钬激光碎石术的肾结石患者的临床资料。结石大小按照所有肾内结石的累积长度计算,而清石则定义为结石完全清除或残余结石〈1mm。结果平均结石大小（横径）为（21.8±7.6）mm。术后初始清石率为64.9%,而术后6个月增加至88.7%。有6.5%的患者出现并发症。下盏结石的初始清石率较其他位置低（P〈0.001）,而非含钙结石的初始清石率明显高于含钙结石（P=0.003）。结论输尿管软镜联合钬激光碎石术用于治疗肾结石患者具有较满意的总体清石率及较低的手术并发症发生率,可作为治疗肾结石尤其是40mm以下肾结石的常规选择。
Objective To evaluate the efficacy and safety of flexible ureteroscopy（FURS）and holmium lithotripsy in the treatment of intra-renal stones.Methods Clinical data of 291 patients with intra-renal stones treated with FURS and holmium lithotripsy during Aug.2011 and Oct.2014 were retrospectively analyzed.The stone size was evaluated by calculating cumulative stone diameter of all stones,and the stone free status was defined as the absence of any stone,or stone fragment1 mmin the kidney.Results The average stone size was（21.8±7.6）mm.The overall primary stone free rate（SFR）was64.9%,which increased to 88.7%six months after the first surgery.Complications developed in 6.5% of patients.Data revealed that lower calyx stones had lower SFR than other stones（P〈0.001）,and non-calcium stones had higher SFR than calcium stones（P=0.003）.Conclusion FURS and holmium lithotripsy can produce satisfactory SFR and low complication rate.It can be a valuable choice for patients with renal stones,especially for stones≤40 mm in diameter.
