Ultrasonic Destruction of Kidney Stones

AUTOR(ES)
RESUMO

Kidney stones may be removed without using a surgical incision by a combination of techniques and skills recently developed in the fields of urology and radiology. Percutaneous access to the kidney is established under fluoroscopic control. A guide wire placed into the renal pelvis allows a nephroscope to be inserted and the collecting system visualized. A long hollow metal probe is advanced through the nephroscope and placed in contact with the stone. This probe conducts the ultrasonic energy. The stone absorbs the energy and breaks into fine granules, which are evacuated by suction.
