摘要
目的探讨体外冲击波碎石术(ESWL)在双J管表面结石形成致拔管困难的处理.方法对6例因管壁结石形成致拔管困难的患者,分别采用仰卧患侧后斜位(20°±)、俯卧患侧前斜位(20°±),以双束交叉x线系统定位,轰击电压从11.2 kV逐渐加至18.1 kV,冲击次数1000～3 000次.结果本组6例患者经ESWL治疗1～2次后,双J管均顺利拔除.结论对管壁结石致拔双J管困难,ESWL是一种简单、安全、有效的方法.
Objective To explore the efficacy of extracorporeal shock wave lithotripsy (ESWL) to coping with lithiasis-in-duced difficulty in withdrawing double J ureteral stents. Methods This study includes 6 patients with difficulty in withdraw-ing the stents due to lithiasis, who were in the anterior prone position or posterior oblique supine position to receive ESWL treatment. The stones were localized by double-band intersection X-ray system. The treatment voltage of shock wave was 11.2 kV initially, which was gradually increased to 18.1 kV, and the shock wave attack amounted to 1 000 to 3 000 times in total. Results and Conclusion After ESWL treatment, the incrusted double J stents were successfully withdrawn in all the 6 cases, without causing any morbidity related to the use of ESWL. Among the various techniques available for removing incrusted double J stents, ESWL appears to be the most effective and the least invasive modality.
