Further study details as provided by Seoul National University Hospital:

Primary Outcome Measures:
  • Stone-free rate at 14th day of study [ Time Frame: 14th day ] [ Designated as safety issue: No ]
    Rate of stone-free as confirmed by non-contrast CT, intravenous urography or simple x-ray (only for radio-opaque stone)


Secondary Outcome Measures:

  • Duration to stone passage within 28days of study [ Time Frame: for 28 days ] [ Designated as safety issue: No ]
  • amount of analgesics used for 28 days of study [ Time Frame: for 28 days ] [ Designated as safety issue: No ]
  • Rate of active treatment [ Time Frame: for 28 days ] [ Designated as safety issue: No ]
    Active treatments include shock-wave lithotripsy, ureteroscopic ureterolithotomy, ureteral stenting or other surgical treatment


Estimated Enrollment: 150

Detailed Description:
  1. Enrollment

    1. patients with ureteral stones of sizes from 3 to 10 mm
    2. patients aged more than 18 years
  2. Randomization

    1. naftopidil 75 mg qd for 14 days or placebo
    2. Standard treatment with pain-killers were also applied.(aceclofenac)
  3. Follow-up for 28 days

    1. We confirm the stone free status by CT or X-ray films at 14th and 28th days.
    2. Rates of active treatment will be also evaluated.
