Some ureteric strictures are so tight that they are difficult to traverse with balloon catheters or internal stents. We present five such cases, which were traversed using a modified through and through technique with a hydrophilic coated guide-wire. The reasons for the difficulty are discussed, and the merits of the modified technique compared with conventional techniques are described.
一些输尿管狭窄非常严重，以至于使用球囊导管或内支架难以通过。我们展示了五例这样的病例，这些病例使用了一种改良的贯穿技术和一根亲水涂层导丝成功通过。讨论了导致困难的原因，并描述了改良技术与传统技术相比的优点。
