Migration of stones and stone fragments during ureteroscopic lithotripsy can lengthen and complicate the procedure, or necessitate subsequent procedures. Traditional baskets or wires may cause trauma to the ureter, interfere with the lithotripter and allow migration of smaller stone fragments.
BackStop™ is a water soluble gel that is delivered above the stone in the ureter and acts to prevent retrograde stone migration during ureteroscopic lithotripsy. Once delivered, the catheter is removed, thus freeing the operating field. BackStop™ is completely atraumatic and will conform to any shape ureter. It has no mechanical parts and will not interfere with the lithotripter. BackStop™ is compatible with all forms of ureteroscopic lithotripsy, including laser and mechanical lithotripters.
When lithotripsy is complete, BackStop™ is dissolved via conventional irrigation and the ureteral occlusion is reversed. |
