Ultrasonic lithotripsy of bladder stones

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.
