Design outcomes

Primary

Measure	Time frame	Description
Change from stone free rate(SFR) with different follow-up periods	Patients in group A and group B return hospital respectively in 1,2 and 4 weeks after RIRS,patients in group C return hospital respectively in 2 and 4 weeks after RIRS.	Primary SFR is assessed by abdominal plain film （KUB）in different follow-up periods after operation. Stone-free status are defined as either the absence of any residual stone fragments.

Secondary

Measure	Time frame	Description
Extracorporeal physical vibration complications	Patients in group A and group B return hospital respectively in 1,2 and 4 weeks after RIRS,patients in group C return hospital respectively in 2 and 4 weeks after RIRS.	Complication is defined as any adverse event occurred
