目的 评价一种自行设计的碎石固定钳在体外实验时的碎石效率.方法 2010年10月选取结石替代品48颗,成分为碳酸钙,大致加工成椭圆形,质量0.5 ～0.7 g,直径约1 cm.随机分成两组,每组各24颗,第1组使用自制激光碎石固定钳,第2组不使用碎石固定钳,两组均采用钬激光碎石.在钬激光能量消耗2 kJ时记录碎石时间及碎除结石质量,至彻底击碎结石后再记录碎石时间及消耗能量.比较两组碎石时间、消耗能量、残余结石的差异.结果 钬激光能量消耗2 kJ时碎石时间,第1组为(4.7 ±0.9) min,第2组为(4.2 ±0.9) min,差异无统计学意义(P＞0.05);能量消耗2 kJ时所碎除结石质量第1组为(0.14 ±0.04)g,第2组为(0.13±0.06)g,差异无统计学意义(P＞0.05);剩余结石碎石时间第1组为(4.5±1.2)min,第2组为(9.2±2.6) min,差异有统计学意义(P＜0.05);剩余结石碎石消耗能量第1组为(1.7±0.5)kJ,第2组为(2.6±0.4)kJ,差异有统计学意义(P＜0.05);第1组总碎石时间为(9.2±1.7)min,总能量消耗为(3.7±0.5)kJ,第2组总碎石时间为(13.4±2.7) min,总能量消耗为(4.6±0.5)kJ,差异均有统计学意义(P＜0.05).结论 体外实验中,自制激光碎石固定钳能明显提高碎石效率,对于直径＜1 cm结石的碎石效率提高更明显.
目的 評價一種自行設計的碎石固定鉗在體外實驗時的碎石效率.方法 2010年10月選取結石替代品48顆,成分為碳痠鈣,大緻加工成橢圓形,質量0.5 ～0.7 g,直徑約1 cm.隨機分成兩組,每組各24顆,第1組使用自製激光碎石固定鉗,第2組不使用碎石固定鉗,兩組均採用鈥激光碎石.在鈥激光能量消耗2 kJ時記錄碎石時間及碎除結石質量,至徹底擊碎結石後再記錄碎石時間及消耗能量.比較兩組碎石時間、消耗能量、殘餘結石的差異.結果 鈥激光能量消耗2 kJ時碎石時間,第1組為(4.7 ±0.9) min,第2組為(4.2 ±0.9) min,差異無統計學意義(P＞0.05);能量消耗2 kJ時所碎除結石質量第1組為(0.14 ±0.04)g,第2組為(0.13±0.06)g,差異無統計學意義(P＞0.05);剩餘結石碎石時間第1組為(4.5±1.2)min,第2組為(9.2±2.6) min,差異有統計學意義(P＜0.05);剩餘結石碎石消耗能量第1組為(1.7±0.5)kJ,第2組為(2.6±0.4)kJ,差異有統計學意義(P＜0.05);第1組總碎石時間為(9.2±1.7)min,總能量消耗為(3.7±0.5)kJ,第2組總碎石時間為(13.4±2.7) min,總能量消耗為(4.6±0.5)kJ,差異均有統計學意義(P＜0.05).結論 體外實驗中,自製激光碎石固定鉗能明顯提高碎石效率,對于直徑＜1 cm結石的碎石效率提高更明顯.

Objective To evaluate the lithotripsy efficiency of a newly calculi anchoring forceps in vitro.Methods Compared the efficiency with or without calculi anchoring forceps in the circumstances imitate percutaneous nephrolithotomy.There are 24 calculus for each group in random selection.The lithotripsy was completed by one people.the time,energy and retained calculus were compared by T-test.Results When the energy expenditure reaches 2 kJ,the operating time was (4.7 ± 0.9) min in group 1 and (4.2 ± 0.9) min in group 2 (P ＞ 0.05).The removal calculus showed no differences between the two groups (P ＞ 0.05).After the energy used over 2 k J,the operating time of the remained calculus were (4.5 ± 1.2) min in group 1 and (9.2 ± 2.6) min in group 2 respectively (P ＜ 0.05),and the energy consumed (1.7 ± 0.5) kJ and (2.6 ± 0.4) kJ respectively (P ＜ 0.05).Total energy consumed in group 1 and group2 was (3.7±0.5) kJ and (4.6±0.5) kJ (P＜0.05).And the cumulate time used was (9.2±1.7) min and (13.4 ±2.7) min in group 1 and group 2 respectively (P ＜0.05).Conclusions The calculi anchoring forceps can improve the efficiency of lithotripsy in vitro.The improvement was significant for the calculus whose diameter was smaller than lcm.
