由于尿路结石病人不断的增多与高复发率,对建立“非出血性”方法治疗尿石症的兴趣在继续增长。电水压波,超声波或冲击波均已用来粉碎结石。应用这些方法根据其大小与部位以治疗肾结石及膀胱结石已取得显著成绩。在另一方面,直到现在输尿管结石还不能常规进行碎石。在这些可用的治疗方法中主要以经尿道用Zeiss套圈牵引结石。这种技术已经发展为PerezCastro输尿管肾镜方法,其中有些病例可以使用Dormia—结石篮在直视下置于结石之上,在结石上张开然后结石与器械同时从输尿管取出。这种方法与Zeiss—套圈方法都不一定能成功;
Interest in establishing a “non-hemorrhagic” approach to treating urolithiasis continues to increase as patients with urolithiasis continue to increase and relapse. Electrohydraulic waves, ultrasonic waves or shock waves have been used to crush stones. The use of these methods according to their size and location to treat kidney stones and bladder stones have made remarkable achievements. On the other hand, ureteral stones have not been routinely detritus until now. Of these available treatments, the stones are primarily pulled with the Zeiss ferrule through the urethra. This technique has evolved into the Perez Castro ureteroscopic approach, in which some cases can be placed on the stone under direct vision using Dormia-stone baskets, open on the stone and the stone and instrument simultaneously removed from the ureter. This method and the Zeiss-ring method are not necessarily successful;
