目的观察输尿管软镜下行钬激光碎石术治疗肾结石的临床疗效。方法选取近两年来我院治疗的102例肾结石患者作为研究对象,所有患者的结石大小在0.9~1.7 cm间,均在输尿管软镜下行钬激光碎石术,观察患者的治疗效果。结果 102例患者中共有108枚结石,寻及104枚,单次碎石成功100例,成功率为92.6%,平均手术时间为50 min,平均住院时间为4d;术后2例出现发热,经抗感染治疗后痊愈,无脓肾、输尿管穿孔并发症发生。所有患者均随访半年以上,无一例结石复发。结论对于肾结石患者在输尿管软镜下采取钬激光碎石治疗疗效显著,碎石成功率高,不易复发,尤其适用于结石体积较小、肾盏无明显积水的患者,值得在临床推广应用。 Objective To observe the clinical effect of ureteroscopic holmium laser lithotripsy on renal calculus. Methods A total of 102 cases of nephrolithiasis treated in our hospital in the past two years were selected as the study objects. The stone size of all the patients was between 0.9 and 1.7 cm. The patients underwent holmium laser lithotripsy under ureteroscope to observe the therapeutic effect. Results A total of 108 stones were found in 102 cases, 104 were found, and 100 cases were successfully treated with single gravel. The success rate was 92.6%, the average operation time was 50 minutes and the average length of hospital stay was 4 days. After 2 cases, fever occurred. Anti-infection cured, no pus kidney, ureteral perforation complications. All patients were followed up more than six months, no case of stone recurrence. Conclusion The treatment of nephrolithotomy with holmium laser lithotripsy under ureteroscope is effective and the success rate of gravel is high and it is not easy to recur. It is especially suitable for patients with small calculus without obvious hydrops of calyces and is worthy of clinical application .
