Outcome Measures

Primary Outcomes (1)

  • stone free rate

    Complete clearance of stones in addition to clinically insignificant residual fragments

    3 months following last session of SWL

Secondary Outcomes (1)

  • Complications rate

    3 months following last session of SWL

Study Arms (2)

Ultraslow shock wave lithotripsy (SWL)

ACTIVE COMPARATOR

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).

Procedure: SWL

Slow power-ramping SWL

ACTIVE COMPARATOR

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.

Procedure: SWL
