Initial experience with the rigid ureteroscope showed that despite ureteral dilation and guide wire followers, introduction of the ureteroscope can be difficult due to bladder mucosa catching on the instrument. A simple, cheap disposable device using a modified ureteric catheter is presented that overcomes this problem.
刚性输尿管镜的初步使用经验表明，尽管进行了输尿管扩张并使用了导丝引导器，但由于膀胱黏膜卡在器械上，输尿管镜的插入仍可能困难。本文介绍了一种使用改良输尿管导管的简单、廉价的一次性装置，该装置克服了这一问题。
