Ultrasonic Lithotripsy

Ultrasonic lithotriptors are very effective in treating large stones. Fragmentation and suction of stone particles occur simultaneously. The large size of these probes requires passage through large, rigid endoscopes.

Advantages of Ultrasonic Lithotripsy

  1. Easy to use
  2. Results are excellent with stone free rates of 95-100%
  3. This is an excellent modality for percutaneous stone removal

Disadvantages of Ultrasonic Lithotripsy

  1. Ultrasonic lithotripsy may cause movement of the stone or fragments in the ureter
  2. Continuous irrigation is necessary to offset the heat generated by the devise
  3. Because the ultrasound requires a relatively large, rigid instrument, most stones treated are limited to the lower ureter.
