title: Accessory instrumentation for ureteroscopy.
abstract: OBJECTIVE
  The use of ureteroscopy for diagnostic and therapeutic applications has evolved rapidly over the past 5 years. The purpose of this review is to discuss recent advances in instrumentation for rigid and flexible ureteroscopy.
  
  
  RESULTS
  Advances in accessory instrumentation can be divided into improvements in ureteral access, irrigation, intracorporeal lithotripsy, and stone extraction. By evaluating in-vitro and clinical evaluations of accessory instrumentation, one can identify specific products that may facilitate a positive ureteroscopic outcome.
  
  
  CONCLUSIONS
  Preoperative preparation is the best predictor of positive outcome after ureteroscope. The cornerstone to preoperative preparation is the proper selection of accessory instrumentation. There is no greater frustration than to see the target but be unable to address it.
