PURPOSE
To examine the safety and compatibility of full-length metal ureteral stent usage with extracorporeal shock wave lithotripsy (SWL).
METHODS
Four Resonance ureteral stents and four special Resonance ureteral stents modified to contain thermocouples were placed unilaterally in eight pigs, with contralateral ureter of each pig serving as its own control. All pigs were subjected to the same SWL protocol in both their ureters. In the animals containing the modified stents, ureter temperature was monitored during treatment. The animals were sacrificed on days 1 and 15 after treatment, and both their ureters were histologically examined.
RESULTS
No statistically significant increase (mean increase of 0.5 degrees C, p > 0.05) of stent temperature was observed during treatment. No differences in histology were observed among ureters containing stents and control ureters at both days 1 and 15 after treatment.
CONCLUSION
SWL appears to be harmless for the ipsilateral ureter.
目的
探讨全长金属输尿管支架在体外冲击波碎石术（SWL）中的安全性和兼容性。
方法
将4个共振输尿管支架和4个经特殊改良以包含热电偶的共振输尿管支架单侧置入8头猪体内，每头猪的对侧输尿管作为自身对照。所有猪的双侧输尿管均接受相同的SWL方案。在置入改良支架的动物中，治疗期间监测输尿管温度。在治疗后第1天和第15天处死动物，并对双侧输尿管进行组织学检查。
结果
治疗期间未观察到支架温度有统计学意义的升高（平均升高0.5摄氏度，p>0.05）。治疗后第1天和第15天，含支架输尿管与对照输尿管在组织学上均未观察到差异。
结论
SWL似乎对同侧输尿管无害。
