Ureteral Access Sheaths
A consistent access pathway within a complex procedure.
During selected ureteroscopic procedures, a ureteral access sheath can provide a passage for repeated scope insertion and withdrawal. Designs differ in inner and outer calibre, working length, dilator configuration, tip geometry, coating and radiopaque features. Device selection must account for anatomy and the potential for insertion-related ureteral injury.

A sheath changes the access and irrigation arrangement around the scope. The effect on outflow, fluid pressure and instrument exchange cannot be understood from sheath diameter alone. Appropriate sizing and insertion judgement remain clinical decisions.

Frequently asked questions
Category guidance—not a substitute for the selected model’s instructions for use.
Is a ureteral access sheath necessary for every ureteroscopy?
No. It is used selectively according to the clinical context and the operating surgeon’s judgement.
Does a larger sheath always improve the procedure?
No. A larger calibre changes access and outflow but must be balanced against anatomy and the risk of ureteral injury.
