The 6.9 F semirigid ureteroscope has a hybrid design that shares the rigid ureteroscope body with the fiberoptic imaging bundle of the flexible ureteroscopes. This allows more space for the inner channel, so that there are two working channels of 3.4 F and 2.3 F. This ureteroscope was used in 65 cases on 57 patients without dilatation of the intramural ureter. It was mainly used for the management of ureteral calculi (29 cases) and for visual diagnostic purposes (28 cases). The double-channel design proved extremely helpful in lithotripsy, while the ability to access the ureter without dilatation gave a consistently clearer picture for diagnostic purposes. Forty-two cases were done under local anesthesia with sedation. In 1 patient a minor perforation developed secondary to use of electrohydraulic lithotripsy (EHL). Postoperatively, 7 patients complained of colic, and in 5 patients a low grade fever developed, while 2 patients had both.
6.9F半硬性输尿管镜采用混合设计，其刚性输尿管镜主体与软性输尿管镜的纤维光学成像束共用。这为内部通道留出了更多空间，因此有两个3.4F和2.3F的工作通道。该输尿管镜用于57例患者的65例病例，未进行壁内输尿管扩张。它主要用于输尿管结石的处理（29例）和视觉诊断（28例）。双通道设计在碎石术中被证明非常有用，而无需扩张即可进入输尿管的能力在诊断时能持续提供更清晰的图像。42例在局部麻醉加镇静下完成。1例患者在使用电液压碎石术（EHL）后出现轻微穿孔。术后，7例患者抱怨绞痛，5例患者出现低热，2例患者两者皆有。
