目的 研究一种新型的碎石固定钳在经皮肾镜钬激光碎石术中的碎石效率的形式.方法 将2013年1月～2016年5月我院148例肾结石患者随机分为两组行经皮肾镜碎石手术,A组74例行钬激光联合碎石固定钳碎石取石,B组74例患者单纯行钬激光碎石取石.统计分析两组手术时间、碎石时间、并发症、手术效率等.结果 A组患者总体手术时间55～180min,平均(95.00±2.19)min.其中碎石时间25～125 min,平均(47.50±1.41)min.B组患者总体手术时间50～185 min,平均(100.00±2.28)min;碎石时间25～100 min,平均(59.90±1.65)min.两组间总体手术时间无明显差异,碎石时间有明显差异.结论 钬激光联合使用碎石固定钳相比单纯使用钬激光碎石可减少碎石时间,提高碎石效率.%Objective To study the efficiency of a new type of lithotripsy fixed plier in holmium laser lithotripsy. Methods From January 2013 to May 2016, 148 patients with nephrolithiasis in our hospital were randomly divided into two groups to perform percutaneous nephrolithotomy, holmium laser combined with lithotripsy by lithotripsy fixed pliers was performed in 74 patients in Group A to remove the stones. 74 patients in Group B simply took holmium laser lithotripsy to remove the stones. Analyzed operation time, lithotripsy time, complications, surgical efficiency of the two groups and so on. Results The total operation time of group A was 55-180 minutes with an average of (95. 00±2. 19) minutes. The lithotripsy time was 25-125min with an average of (47. 50±1. 41) min. Patients in group B had a total operation time of 50-185 minutes with an average of (100. 00±2. 28) minutes; The lithotripsy time was 25-100 minutes with an average of (59. 90±1. 65) minutes. There was no significant difference between the two groups in the overall operation time, and the lithotripsy time was significantly different. Conclusion The holmium laser combined with lithotripsy fixed pliers can reduce the lithotripsy time and improve the lithotripsy efficiency as compared with pure holmium laser lithotripsy.
