Extracorporeal shock wave lithotripsy monotherapy for bladder stones.

This report presents our initial experience in 36 patients with bladder stones, treated by extracorporeal shock wave lithotripsy. Minute fragmentation and uncomplicated evacuation occurred in 26 patients (72%). Mean treatment duration was 55 minutes. Mean number of shock waves was 3600 and electrical discharge averaged 24 kV per shock wave. No morbidity, during or after treatment, was encountered in these patients. The treatment was performed without the use of anaesthesia on an outpatient basis.
