经尿道逆行输尿管镜检查近两年在许多地方已成为一种标准方法。然而,在有梗阻的近侧段输尿管结石,对这种新方法仍然是一个难题。经皮通道处理上部输尿管结石仅有少数报导。方法:用一个带套囊的输尿管导管,插入结石下方的输尿管,堵塞在结石下方。然后使患者转向俯卧位,通过一适当的后部下极或中盏,建立一经皮通道。扩大通道至26F,然后插入手术用肾镜(Storz26F)。当输尿管肾盂接合处确定后,偏转整个肾脏,直到能一直看到输尿管内。然后先将光学系统以及肾镜内鞘撤出,插入11F的输尿等镜。为了便于进入输尿管,先向下放置一根安全导丝进入输尿管。用此导丝指引,到达输尿管肾盂连接处是容易确定 Transurethral retrograde ureteroscopy has become a standard method in many places over the past two years. However, proximal ureteral stones with obstruction remain a challenge for this new approach. Percutaneous channel treatment of upper ureteral calculi only a few reports. METHODS: A ureter catheter with a cuff was inserted into the ureter below the stones and clogged under the stones. The patient is then turned to the prone position and a percutaneous access is established through an appropriate posterior pole or mid-caliber. Expand the access to 26F and insert the surgical kidney mirror (Storz26F). When the ureteropelvic junction is identified, the entire kidney is deflected until the ureter can be seen all the time. Then the optical system and the inner sheath of the nephrolithotomy were withdrawn and inserted into the 11F ureteroscope. In order to facilitate access to the ureter, first place a safety guide wire down into the ureter. Guided by this guide wire, reaching the ureteropelvic junction is easy to determine
