Abstract
In 2003, Russian developers proposed a new method of crushing stones by electric impulses of nanosecond duration, which has several advantages over contact electrohydraulic lithotripsy. The aim of the study was to evaluate the possibilities of transfistular nanoelectroimpulse lithotripsy (NEIL) in the treatment of choledocholithiasis. A nanoelectroimpulse lithotriptor "Urolit", manufactured by Medline Ltd. (Tomsk, Russia), was used to break down the gallstones. 66 patients with large and/or unmovable bile duct stones and bile ducts drains were performed transfistular NEIL. It was successful in 63 patients (95.5%). NEIL made it possible to perform removal of large and/or unmovable gallstones without destroying the sphincters of the major duodenal papilla in 89% cases. Transfistular NEIL is a new highly effective and safe method of crushing gallstones.
