GEL-FORMING SYSTEM FOR REMOVING URINARY CALCULI AND FRAGMENTS THEREOF

摘要

The present invention (i) providing compositions (A) and (B), (ii) urinary stones and / or fragments thereof to be removed, particularly kidney stones and / or their fragments, under conditions capable of crosslinking the cationic crosslinkable polymer (s) upon contact of composition (A) with composition (B) Introducing the compositions (A) and (B) above into the urethra, particularly the kidney site, containing fragments, partially or completely surrounding the urolithiasis and / or fragments thereof to be removed, in particular kidney stones and / or fragments thereof. Forming a crosslinked gel, (iii) removing the crosslinked gel with urinary stones and / or fragments thereof, particularly kidney stones and / or fragments thereof, surrounded by a crosslinking gel from the urethra, particularly the kidneys. Urolithiasis and / or fragments thereof to be removed, particularly urethra containing kidney stones and / or fragments thereof, particularly urolithiasis and / or fragments thereof, particularly kidney stones and / or fragments thereof, For use in methods for removing urolithiasis fragments, especially kidney stone fragments Composition (A) comprising one or several cationic crosslinkable polymer (s) and composition comprising one or several crosslinking agent (s) for crosslinking the cationic crosslinkable polymer (s) It relates to a gel forming system consisting of or comprising (B), in particular an adhesive forming system.
