New fiberoptic scopes, originally designed for biliary tract operations, were used in 23 cases for removal of residual calculi at pyelolithotomy and for examination of the renal pelvis and ureter. The external diameters of the scopes are 6.6 mm. (CHF-X1) and 4.5 mm. (CHF-X2). Water irrigation and forceps manipulation can be performed simultaneously with the CHF-X1 scope but only irrigation can be done with the CHF-X2 scope. The scopes were reliable and allowed easy endoscopic forceps manipulation. Improvements for an ideal fibroptic nephroscope are discussed.
最初设计用于胆道手术的新型纤维光学内窥镜，被应用于23例肾盂切开取石术后残余结石清除及肾盂和输尿管检查。这些内窥镜的外径分别为6.6毫米（CHF-X1）和4.5毫米（CHF-X2）。使用CHF-X1内窥镜时可同时进行水冲洗和钳夹操作，而CHF-X2内窥镜仅能进行冲洗。这些内窥镜性能可靠，便于进行内镜钳夹操作。文中还讨论了理想纤维肾镜的改进措施。
