title: Transurethral removal of large ureteral and renal pelvic calculi using ureteroscopic ultrasonic lithotripsy.
abstract: Transurethral ultrasonic fragmentation of stones allows successful endoscopic removal of upper urinary calculi that otherwise would be considered too large to extract. We successfully extracted endoscopically 2 large renal pelvic and 5 large ureteral stones using transurethral ureteropyeloscopy and ultrasonic lithotripsy. The stone is visualized first with the ureteropyeloscope, and then engaged in a basket and either fragmented or disintegrated with the ultrasonic transducer. Any remaining small stone fragments can be retrieved with a stone basket or forceps. There has been little morbidity with this procedure and patients can return to normal activity after discharge from the hospital.
