应用经皮肾微造瘘输尿管镜二期取石方法，采用腔内弹导碎石器碎石，共７７次治疗３７例４２侧肾铸型或多发结石和输尿管上段结石。结石１次取净１２例，２次取净１８例，３次取净３例，取净率达８０％以上。认为采用小穿刺通道，输尿管镜及腔内弹导碎石，是一种安全、有效的治疗方法。该方法可代替经皮肾镜取石，其优点在于穿刺通道细小、创伤小、痛苦轻、术中出血及合并症少，输尿管镜可到达大部分肾盏及输尿管上段，结石清除较彻底，尤其为治疗复杂性肾石提供了新的治疗手段。
Application of percutaneous nephrostomy ureteroscopy second stage stone method, the use of intracavity ballistic guided lithotripsy gravel, a total of 77 treatment of 42 cases of 42 cases of renal cast or multiple stones and ureteral stones. Take stones in 1 case of net in 12 cases, 2 times to take the net in 18 cases, 3 times to take the net in 3 cases, take the net rate of 80% or more. That the use of small puncture access, ureteroscopy and intracavity missile shells, is a safe and effective treatment. The method can replace percutaneous nephrolithotomy, which has the advantages of small puncture channel, less trauma, less pain, less bleeding and complications during operation, ureteroscopy can reach most of the calyx and upper ureter, and stone removal is more thorough, especially Treatment of complex nephrology provides a new treatment.
