Fiberscopes for the observation of the upper urinary tract (pyeloureteroscopes) have improved markedly in terms of resolution and durability. With these improved pyeloureteroscopes, transurethral observation of upper urinary tract lesions was performed 42 times in 40 cases from April 1979 to May 1983. The guide tube method (J. Urol. 112: 176-178, 1974) was used for insertion of the fiberscope into the ureter. At present, our transurethrally passed pyeloureteroscope is useful in the diagnosis of some upper urinary tract lesions which are not visualized or confirmed by other current image diagnostic procedures. However, it should be noted that it does not visualize all parts of the upper urinary tract - especially the lower calyx. Insertion to the target is also sometimes difficult and we must be careful in the interpretation of findings because of inevitable image distortion and the similarity between inflammation and urothelial tumor.
用于观察上尿路的纤维内镜（肾盂输尿管镜）在分辨率和耐用性方面有了显著提高。使用这些改进后的肾盂输尿管镜，在1979年4月至1983年5月期间，对40例患者进行了42次经尿道对上尿路病变的观察。采用导管法（《泌尿学杂志》112: 176 - 178, 1974）将纤维内镜插入输尿管。目前，我们经尿道插入的肾盂输尿管镜对于某些上尿路病变的诊断很有用，这些病变通过其他当前的影像诊断方法无法看到或确诊。然而，应当注意的是，它并不能观察到上尿路的所有部位——尤其是下肾盏。有时将其插入目标部位也很困难，而且由于不可避免的图像失真以及炎症与尿路上皮肿瘤之间的相似性，我们在解读检查结果时必须谨慎。
