Unique Antiretropulsion Device - Gel rather than mechanical device. After the gel is placed, the catheter is removed, freeing up space in the ureter.
Animation - shows how BackStop Gel prevents stone migration during lithotripsy.
Reverse-thermosensitive Gel - at room temperature it is a soft, injectable gel and at body temperature it increases in viscosity to form a plug.
Kits include a 3F or 5F catheter with radiopaque distal tip and a 5mL syringe of Backstop Gel.
Reusable Injector designed to inject Backstop Gel.
Effective Antiretropulsion Device - prevents stone migration during lithotripsy.1 Increases fragmentation efficiency in bench studies.2
Easy to remove - dissolved 100% of the time in clinical studies.1,3

A reverse-thermosensitive gel that forms a plug in the ureter to prevent stone migration during lithotripsy, making stone cases more predictable.

Product Details

Effective Antiretropulsion Device

  • Prevents stone migration during lithotripsy1
  • Completely occludes the ureter, preventing migration of stone fragments of all sizes 
  • Increases fragmentation efficiency, as demonstrated in a bench study2
  • May be used with laser, pneumatic and ultrasonic lithotripters

Unique Antiretropulsion Device

  • Gel rather than mechanical device
  • Gel conforms to the ureter
  • After the gel is placed, the catheter is removed, freeing the field

Easy to Place, Easy to Remove

  • Place with 3F catheter under direct visualization or with a 5F catheter under fluoroscopic guidance
  • Flush with conventional irrigation
  • Dissolved 100% of the time in clinical studies1,3

Clinical Information

Stone Retropulsion Study

 

In a randomized, prospective, multi-center study, the BackStop Device group had a lower rate of retropulsion (9%) vs. the control group (53%).1

Backstop Gel reduced the occurrence of stone migration in ureteroscopy with ISWL cases.
