A ureteral introduction sheath is a flexible tube designed to create a protected pathway for accessing the ureter during urological procedures. Clinically, it facilitates the insertion of other instruments—such as endoscopes or catheters—and allows for guidewire exchanges without direct contact with the ureteral walls, reducing trauma and improving procedural safety.
These devices are typically single-use and regulated as medical instruments, with classification and supply rules varying by jurisdiction. They may be used in both transurethral and percutaneous approaches, often paired with an inner dilator to ease insertion, though they do not include all components of a full ureteral introduction set.
