title: Performing flexible ureteroscopy through a cystoscopy introducer sheath.
abstract: Performing flexible ureteroscopy through a cystoscope sheath positioned with its tip near the orifice of the ureter prevents buckling of the ureteroscope and decreases the friction against the ureteroscope. This results in more precise translation of the surgeon's movements to the tip of the instrument and facilitates the procedure.
