Ultrasonic destruction and endoscopic removal of kidney, ureteral, bladder and urethral stones.

Endoscopic removal of renal calculi was introduced at our department in 1984, first in Hungary and East-Europe. Renal, ureteral, bladder and urethral calculi are all endoscopically removed partially following ultrasonic destruction. The procedure is similarly used in cases of solitary kidney or of kidneys with staghorn calculi. Several hundreds of successful cases have proved the necessity and importance of the procedure.
