Brief summary

To evaluate the safety and efficacy of LithoVue ureteroscope system in Chinese population.

Detailed description

This is a prospective, multicenter, single-arm, pre-market study.The aim of this study is to evaluate the safety and efficacy of LithoVue ureteroscope system in Chinese population, to support the regulatory approval by CFDA. The study will enroll 60 patients in 3 investigational sites in China. The primary endpoint is procedure success rate of LithoVue ureteroscope system, the procedure success is defined as:Scope condition is suitable to complete the procedure and not requiring immediate scope substitution; it is also considered as a procedure success if the clinical effect is the same as that from the LithoVue scope per investigator's judgement in the case of a scope change (non-LithoVue).

Interventions

DEVICELithoVue Ureteroscope System

The LithoVue System is intended to be used to visualize organs, cavities and canals in the urinary tract (urethra, bladder, ureter, calyces and renal papillae) via transurethral or percutaneous access routes.
