Ultrasonic lithotripsy of bladder stones

Abstract

In the second half of 1985, 15 patients with 25 bladder stones were treated with Lutzeyer's Ultrasonic Lithotriptor. Of the patients 13 underwent additional operations, mostly transurethral resection of the prostate. The average duration of lithotripsy was 30.5 minutes. Some difficulties were experienced especially when drilling hard stones and as a complication late urethral bleeding occurred in one patient.

Extracorporeal Shock Wave Lithotripsy for Bladder Stones

“…Both require anaesthesia and hospitalisation and are associated with some morbidity. Larger stones require the help of the ultrasound or electrohydraulic lithotriptor (Cetin et al, 1988 ;Yip and Tin, 1988;Zhaowu et al, 1988). While using these ancillary aids it is possible, as a result of friction, to erode the mucosa of the bladder or perforate the bladder.…”

“…These procedures are also time-consuming. Cetin et al (1988) reported urethral bleeding as a result of lithotresis of hard stones.…”
