Abstract:
The present invention improves significantly the success rate of lithotripsy and reduces the risk of tissue damage, by injecting a temporary plug in front, and optionally behind a concretion (for extracorporeal lithotripsy) or behind a concretion (for intracorporeal lithotripsy). One aspect of the present invention relates to injecting an inverse thermosensitive polymer solution into a lumen, thereby preventing the migration of a concretion, or its fragments, upon extracorporeal or intracorporeal lithotripsy.
