title: Novel technique for fragment removal after percutaneous management of large-volume neobladder calculi.
abstract: OBJECTIVE
  To describe a novel method for fragment evacuation after percutaneous lithotripsy of neobladder calculi.
  
  
  METHODS
  The technique was developed using a Urovac bladder evacuator, which was attached to a standard 30F Amplatz working sheath.
  
  
  RESULTS
  The attachment of the Urovac evacuator to the Amplatz sheath rapidly evacuated large quantities of stone material. Careful attention should be paid to maintaining low-pressure irrigation by ensuring the bladder is not overly full and the Urovac device is not vigorously manipulated, to minimize the likelihood of bladder injury.
  
  
  CONCLUSIONS
  Percutaneous ultrasonic/hydraulic lithotripsy for large-volume neobladder calculi often results in a substantial burden of stone fragments that can be difficult to clear using standard techniques. Attaching a Urovac bladder evacuator to the 30F Amplatz sheath can simplify the management of this task.
