New-generation flexible ureterorenoscopes are more durable than previous ones

摘要: Abstract Objectives To determine the deterioration in maximal active deflection and flow capabilities of a new-generation flexible ureteroscope (URS). Methods We performed 50 ureterorenoscopies using same URS: Karl Storz 11278 AU1 Flex-X, which is capable 270° ventral dorsal directions. Postoperatively, we evaluated deflection, irrigation at 100 cm H 2 O, number broken optical fibers. Results The URS was used for total 76 hours, 15 minutes (average 95 per procedure). had deteriorated from to 208° last procedure. decreased 133°. O mL/min initially 40 image fibers reached six 50th One repair necessary procedure because laser perforation working channel. Conclusions need occurs less frequently with URSs, especially when they are by an experienced endourologist. In future, improvements durability will still be key widespread use technique limit damage
