Cost-effectiveness of anti-retropulsion devices for ureteroscopic pneumatic lithotripsy.
Olweny E, Eisner B, Stoller M
Conclusion: “Anti-retropulsion devices are cost-effective at retropulsion rates of 14% or greater. … use of antiretropulsion devices can potentially reduce costs and secondary procedures, leading to improvements in patient care.”
Anti-retropulsion devices increase stone fragmentation efficacy with holmium:YAG laser lithotripsy.
Jonat LM, Chew BH, Lange D, Paterson RF, Teichman JM
Conclusion: “Anti-retropulsion devices increase stone fragmentation efficiency and facilitate high power lithotripsy...”
The Accordion device for avoiding ureteral retrograde stone migration: Initial Brazilian experience.
Mitre AI, Pagotto VdC, Pagotto CJ, MD, Dénes FT, Ebaid GX, Rocha FT, Gromatsky C
Conclusion: “The Accordion device effectively occluded the ureter preventing retrograde migration of clinically-relevant calculi or fragments during ureteroscopic pneumatic ballistic or laser lithotripsy.”
The capability of antiretropulsion devices to redirect fluid irrigation during ureteroscopy.
Poh BK, Jonat LM, Lange D, Chew BH
Conclusion: “The Accordion reduces the amount of irrigation that reaches the kidney during ureteroscopy and significantly increases the backflow or irrigation that potentially increases the amount of fragments washed into the bladder…”
Ability of antiretropulsion devices to prevent intrarenal pressure rise in ex vivo porcine model.
Rothberg MB, Suh LK, Gupta M
Conclusion: “…the film-based device provided superior ability to diminish intrarenal pressures at all three irrigation pressures. In some instances the film-based device completely occluded the ureter, preventing any pressure transmission from irrigation fluid into the collecting system.”
