Zebra guidewire damage by Holmium: YAG laser and management of removal.

The zebra guidewire is widely used in endoscopic surgery. Because of its central mental core, it is not easy to break or shear off within the urinary tract. We report a case about the breakage of zebra guidewire in ureteroscopy (URS) with Holmium: YAG laser lithotripsy. It is easily to be managed by percutaneous access or open surgery. For the purpose of minimal invasiveness and risk, we performed a retrograde flexible ureteroscopy and extracted it successfully without any complication. To our knowledge, this is the first case report on flexible ureteroscopy to remove the residual tip of damaged guidewire in renal.
