Handling and prevention of complications in stone basketing

Several studies of ureteroscopic treatment for ureteral stones have reported that most stone clearance failures can be attributed to stone fragment retropulsion. Stone retropulsion can result in increased operative time and cost-resulting from the need to change from the semi-rigid ureteroscope to a flexible instrument to chase migrated calculi-and additional procedures to treat residual migrated fragments are often required. The degree of migration depends mainly on the energy source used for lithotripsy; pneumatic and electrohydraulic lithotripters are associated with a greater degree of retropulsion than lasers. Different stone-trapping strategies and devices have been developed to minimize stone migration. Novel devices include the Lithovac(®) suction device, the Passport(™) balloon, the Stone Cone(™), the PercSys Accordion(®), the NTrap(®), and stone baskets such as the LithoCatch(™), the Parachute(™), and the Escape(®). Some authors have also reported on the use of lubricating jelly and BackStop(®) gel (a reverse thermosensitive polymeric plug); these devices are instilled proximal to the stone prior to the application of kinetic energy in order to prevent retrograde stone migration.

Preventing stone retropulsion during intracorporeal lithotripsy

Retrograde exploration of the ureter and kidneys is currently a widely used and well-established procedure to deal with problems of a diagnostic and therapeutic nature with reduced invasiveness. The process of miniaturizing the instruments combined with the steady improvement in video quality has continuously amplified its potential applications, maintaining the procedure safe and rapid. During an operation, however, unexpected events may condition a change to the programme or determine the onset of even more serious complications. Our aim is to analyze such events and complications and recommend potential solutions to prevent and/or deal with such happenings.

Ureterorenoscopy: avoiding and managing the complications.

Background and Purpose: A serious problem during calculus retrieval is the inability to release a stone from the basket. We evaluated a variety of basket designs to address this issue in two in-vit...
