Brief Summary:
Percutaneous nephrolithotomy PNL in conjunction with intracorporeal lithotripsy allows for the rapid removal of any kidney stone regardless of size Currently the choice of intracorporeal lithotripters includes ultrasonic pneumatic and combined ultrasonicpneumatic energy sources Recently a novel dual probe design as been introduced by Cybersonics of Erie Pennsylvania This dual probe intracorporeal lithotrite is called the Cyberwand and is composed of a fixed inner probe vibrating at an ultrasonic frequency with an outer probe vibrating at about 1000 Hz As this new design has the potential to revolutionize intracorporeal lithotripsy we intend to compare this novel technology to currently available lithotripsy technology in a randomized clinical trial
Detailed Description:
Percutaneous nephrolithotomy PNL is used to remove large and complex stones from the upper urinary tract Intracorporeal lithotripsy is an integral part of PNL Commercially available intracorporeal lithotripsy modalities include ultrasonic pneumatic and combined ultrasonic and pneumatic models Each modality has its inherent advantages and disadvantages Ultrasonic lithotrites are capable of fragmenting stones while concomitantly suctioning out fragments Unfortunately some stones are hard enough to resist fragmentation from ultrasonic lithotripsy Pneumatic lithotrites are able to fragment all stones regardless of hardness but this modality is unable to suction out stone pieces at the same time fragmentation is occurring The newest lithotrite which combines both ultrasonic and pneumatic components is capable of fragmenting any stone but also has some inherent limitations The handpiece of the lithotripsy device is somewhat cumbersome the suction component can clog and the device has overheated at the maximal settings Kuo et al Current intracorporeal lithotrites while functional can certainly be improved
