A novel universal-length ureteral stent simplifies placement for antegrade internal procedures. This design reduces the need for precise measurements, offering economic benefits for interventional radiology practices.

Area of Science:

  • Urology
  • Medical Devices
  • Interventional Radiology

Background:

  • Ureteral stents are crucial for managing ureteral obstructions.
  • Accurate stent sizing and placement can be challenging, requiring precise measurements.
  • Existing stent designs may necessitate multiple sizes for different patient anatomies.

Purpose of the Study:

  • To introduce a universal-length ureteral stent designed for simplified antegrade internal placement.
  • To eliminate the need for pre-procedure measurement of the ureteropelvic to ureterovesical junction.
  • To demonstrate the economic advantages for interventional radiology practices.

Main Methods:

  • Development of a universal-length ureteral stent from a biocompatible copolymer.
  • Incorporation of a double-looped distal end for adaptable length adjustment.
