title: Modern flexible ureteroscopy in Cohen cross-trigonal ureteral reimplantations.
abstract: OBJECTIVE
  We describe a feasible flexible ureteroscopy (fURS) technique with the latest instruments to and to discuss their advantages.
  
  
  METHODS
  Three patients underwent a fURS for stone treatment. A 7F angled orifice catheter and a hydrophilic angled tip stiff wire is used to guide the wire in the proper ureteral direction sighting the ureter allowing the use of a 10/12 ureteral access sheath. A single use ureteroscope was used.
  
  
  RESULTS
  All of them had successful ureteral access and laser lithotripsy being stone free endoscopically. No complications reported.
  
  
  CONCLUSIONS
  The modern fURS technique was found feasible and safe in patients with cross-trigonal ureteroneocystostomy.
