What am I looking at?
Visual recognition

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Catheter advanced within the ureter for access, retrograde or antegrade contrast injection, or to help cross a narrowed segment. Typical procedural contexts include nephroureteral procedures, ureteral opacification, and obstruction crossing.
What most clearly distinguishes it from similar devices?
Key distinctions
This is a low-profile ureteral working catheter for access and contrast injection, not a retention stent intended to remain across the ureter after the procedure.
