Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Provides completely internal ureteral drainage across obstruction, stricture, stones, or a recently treated segment by spanning the renal pelvis to the bladder without an external catheter limb.
What most clearly distinguishes it from similar devices?
Key distinctions
The two curled ends anchor the stent internally in the renal pelvis and bladder, allowing completely internal urinary drainage without an external catheter limb.
