Transurethral ultrasonic ureterolithotripsy using a solid-wire probe.

A multicenter study evaluates a new technique for transurethral ultrasonic ureterolithotripsy utilizing a solid-wire probe. The transverse vibrations of the probe cause greater stone disintegration. A small ureteroscope is used and a basket is not required. There was a 96.6 per cent success rate in 118 cases. This technique has significantly improved ultrasonic lithotripsy. It has proved to be useful for upper ureteral stones not amenable to extracorporeal shock-wave lithotripsy and lower ureteral stones including "steinstrasse."

Ultrasonic and electrohydraulic lithotripsy of ureteral calculi.

Ultrasonic lithotripsy of ureteral calculi has been accomplished using a fine flexible ultrasonic probe under direct visual control through a 9-F rigid ureteroscope. Electrohydraulic ureterolithotripsy was performed by passing a 5-F catheter-electrode cystoscopically under fluoroscopic control. Case reports are presented. It is concluded that ultrasonic ureterolithotripsy, using the technique described, is a feasible and safe method. Although stone fragmentation by electrohydraulic ureterolithotripsy is possible, the danger of ureteral injury and urinary extravasation is appreciable.
