Two types of operative fiberoptic nephroureteroscopes were developed with the cooperation of the Olympus Optical Company mainly to remove the upper urinary tract calculi. Removal of the renal and upper ureteral stones was attempted in nine cases. The ureter was dilated with olive tip, balloon and Teflon dilators alone or in combination. The combination of balloon and Teflon dilators seemed the most promising. As a result of ureteral dilation, operative fiberoptic nephroureteroscopes, 4.5 mm and 3.5 mm in diameter, could be passed into the ureter in all the cases and the stones could be visualized clearly. Four of the 7 upper ureteral stones and 1 of the 2 pelvic stones could be removed. The success ratio was 56%. The method of stone removal still requires improvement. At present, application of the operative fiberoptic nephroureteroscope is indicated for upper ureteral and renal stones less than 1.0 cm in diameter. With the improved techniques of stone removal using this fiberscope, the indications of extracorporeal shock-wave lithotripsy or percutaneous nephrolithotripsy will probably be greatly reduced in the near future.
在奥林巴斯光学公司的合作下，开发了两种手术用纤维光学肾输尿管镜，主要用于清除上尿路结石。对9例患者尝试进行肾脏和上段输尿管结石清除术。单独或联合使用橄榄头、球囊和聚四氟乙烯扩张器对输尿管进行扩张。球囊和聚四氟乙烯扩张器联合使用似乎最具前景。经输尿管扩张后，直径4.5毫米和3.5毫米的手术用纤维光学肾输尿管镜在所有病例中均能插入输尿管，结石能清晰可见。7例上段输尿管结石中的4例以及2例肾盂结石中的1例被成功清除。成功率为56%。结石清除方法仍需改进。目前，手术用纤维光学肾输尿管镜适用于直径小于1.0厘米的上段输尿管结石和肾结石。随着使用该纤维镜清除结石技术的改进，在不久的将来，体外冲击波碎石术或经皮肾镜取石术的适应证可能会大幅减少。
