摘要

介绍：当前研究的目的是比较瑞士LithoClast®Trilogy Max手机和瑞士LithoClast®Trilogy手机在标准化的体外和体内实验设置的边界。材料和方法：体外设置时，将PVC管置于充满生理盐水的塑料盒内。制作了5个软石和5个硬石，并对碎石机进行了评估，直到完全清除石头。在体内部分的研究中，使用了四头母猪。经皮入路成功后，在骨盆骨系统内放置5颗软硬人工结石。进行碎石术。使用测功机评估过程中所需的力，同时记录石头清除时间。结果：共完成体外和体内实验各20次。瑞士LithoClast®三部曲手机重1200克，瑞士LithoClast®三部曲Max手机重900克。在体外环境中，瑞士LithoClast®Trilogy手机对硬石和软石的平均SCT（结石清除时间）分别为17.8±2.3 s和7.4±1.1 s。瑞士LithoClast®Trilogy Max手机的平均SCT为硬石16.8±2.9 s，软石7±1.2 s。在体内环境中，瑞士LithoClast®Trilogy手机的平均SCT为硬结石36.2±4.4秒，软结石16.2±1.4秒。对于瑞士LithoClast®Trilogy Max手机，硬石和软石的平均SCT分别为32.4±5.8 s和14.8±1.1 s。使用Swiss LithoClast®Trilogy手机时，外科医生的平均施力为36.8±2.5 N，使用Trilogy Max手机时为25.9±3.7 N （p®Trilogy Max手机）。结论：LithoClast®Trilogy和LithoClast®Trilogy Max在碎石术方面同样有效。Max手机的重量减轻，外科医生在骨盆骨系统内的操作和导航方面需要更少的努力。

In vivo and in vitro evaluation of the Swiss LithoClast^® Trilogy Max Handpiece.

Introduction: The aim of the current study is the comparison between the Swiss LithoClast^® Trilogy Max Handpiece and the Swiss Lithoclast^® Trilogy Handpiece in the boundaries of a standardized in vitro and in vivo experimental set-up.

Materials and methods: For the in vitro setup, a PVC tube placed within a plastic box filled with saline solution was used. Five soft and five hard artificial stones were created and the lithotripters were evaluated until complete stone clearance. For the in vivo part of the study, four female pigs were used. After the achievement of percutaneous access, five soft and five hard artificial stones were placed in the pelvicalyceal system. Lithotripsy was conducted. A dynamometer was used to evaluate the force needed during the procedure, while the stone clearance time was recorded.

Results: Twenty in vitro and 20 in vivo trials were completed. The Swiss LithoClast^® Trilogy Handpiece weights 1200gr and the Swiss LithoClast^® Trilogy Max Handpiece weights 900gr. In the in vitro setting, the mean SCT(stone clearance time) of the Swiss LithoClast^® Trilogy Handpiece was 17.8±2.3 s and 7.4±1.1 s for hard and soft stones, respectively. The mean SCT of the Swiss LithoClast^® Trilogy Max Handpiece was 16.8±2.9 s for hard and 7±1.2 s for soft stones. In the in vivo setting, the mean SCT of the Swiss LithoClast^® Trilogy Handpiece was 36.2±4.4 s for the hard and 16.2±1.4 s for the soft stones. As for the Swiss LithoClast^® Trilogy Max Handpiece, the mean SCT for the hard and soft stones was 32.4±5.8 s and 14.8±1.1 s, respectively. The mean applied efforts by the surgeon were 36.8±2.5 N for the Swiss LithoClast^® Trilogy Handpiece and 25.9±3.7 N (p < 0.01) for the Swiss LithoClast^® Trilogy Max Handpiece.

Conclusion: LithoClast^® Trilogy and LithoClast^® Trilogy Max are equally efficient in terms of lithotripsy. The reduced weight of the Max handpiece demands less effort from the surgeon regarding manipulation and navigation inside the pelvicalyceal system.
