Primary Outcome Measures:
  • Difference of the treatment success rate in two weeks after ESWL between treatment group and placebo group [ Time Frame: 2 weeks after ESWL ]
    Treatment success is defined as no or less than 3 mm size remnant stone

Secondary Outcome Measures:
  • Difference of the treatment success rate after ESWL between treatment group and placebo group [ Time Frame: 4, 6 weeks after ESWL ]
    Treatment success is defined as no or less than 3 mm size remnant stone

  • Adverse Event [ Time Frame: 2,4,6weeks ]
    Rate of total Adverse Events and Adverse Events relevant to Investigational drug

  • pain scale [ Time Frame: baseline, 2, 4, 6 weeks ]
    visual analogue pain scale due to urinary stone

  • rate of additional intervention [ Time Frame: 6 week ]
    incidence of additional intervention for the urinary stone ex> ureteral stent insertion, percutaneous nephrostomy, ureteroscopic ureterolithotomy, percutaneous nephrolithotomy, laparoscopic stone removal and so on

Other Outcome Measures:
  • time to stone expulsion [ Time Frame: 2,4,6week ]
    the time (days) elapsed from first ESWL to the expulsion of the stone

  • Number of ESWL [ Time Frame: 6week ]
    The number of required ESWL for the stone expulsion

Estimated Enrollment: 130
