Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Although a safety guidewire (SGW) is commonly recommended in order to reduce the complication rate it may well be that the SGW itself may inhibit the passage of the ureteroscope due to increased friction.
The forces needed to move the ureteroscope in the ureter have not been investigated properly.
The intention in this study is to measure the forces needed to advance and withdraw the ureteroscope in the ureter with and without the SGW in place.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
A - with SGW
Measurement of the forces needed to passage the ureteroscope in the ureter with a SGW in place.
Ureteroscopy with and without safety guidewire
In study arm A - with SGW, the force measurements are made with a safety guidewire in place. In study arm B - without SGW, the force measurements are made without SGW.
B - without SGW
Measurement of the forces needed to passage the ureteroscope in the ureter without a SGW in place.
Ureteroscopy with and without safety guidewire
In study arm A - with SGW, the force measurements are made with a safety guidewire in place. In study arm B - without SGW, the force measurements are made without SGW.
