Ultraslow shock wave lithotripsy (SWL)
Slow power-ramping SWL
SWL at ultraslow rate of 30 SW/min. Power ramping at the first 100 SW from 6 to 18 kv followed by safety pause for two minutes then power ramping from 18 to 22kv during the second 100 SW followed by safety pause for another two minutes. The rest of the session at 22kv (full power).
SWL at a slow rate of 60 SW/min. Power ramping from 6 - 10 kv during the first 500 SW then from 11 - 14 kv during the second 500 SW then from 15 - 18 kv during the following 500 SW then from 19 - 22 kv during the remaining 1000 - 1500 SW.
