Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Medical Expulsive Therapy for Ureter Stone Using Naftopidil: Multicenter, Randomized, Double-blind, Placebo Controlled Study

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:
  • Stone-free rate at 28th day of study [ Time Frame: 28th day ] [ Designated as safety issue: No ]
  • 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

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.

Ages Eligible for Study:   20 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • >= 20 years
  • single 3 to 10 mm ureter stone (longest diameter)

Exclusion Criteria:

  • Presence of multiple ureter stones
  • Renal insufficiency (serum Cr > 1.4 mg/dL)
  • Febrile urinary tract infections(fever > 38°C, evidence of urinary infection)
  • pregnancy or breast feeding
  • solitary kidney
  • hypersensitivity to naftopidil
  • current use of any alpha-blocker, calcium-channel blocker, corticosteroid (within 4 weeks)
  • moderate or severe cardiovascular or cerebrovascular disease
  • hepatic dysfunction (>2 x normal upper limit)
  • significant active medical illness which in the opinion of the investigator would preclude protocol treatment
