The majority of kidney stones are treated with shock wave lithotripsy (SWL). We are examining if the medication Flomax will result in improved stone passage rates following SWL.

Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label

Primary Outcome Measures:
  • Time to Passage of Stone Fragments [ Time Frame: 2 weeks and 3 months ] [ Designated as safety issue: No ]
    Time to passage of stone fragments following shock wave lithotripsy as documented by patient diaries and follow-up radiographic imaging.

Secondary Outcome Measures:
  • Medical Evaluation [ Time Frame: 2 weeks and 3 months ] [ Designated as safety issue: Yes ]
    Evaluation of pain assessments, lower urinary tract symptoms, side effects of study medication and need for hospitalizations and additional endoscopic procedures.

Enrollment: 24
Study Start Date: April 2005
Study Completion Date: February 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Flomax
Patients on this arm will be given 0.4mg of Flomax to be taken for one month following their shock wave lithotripsy procedure.
Drug: Flomax
0.4mg Flomax pills will be given to patients to take once daily for one month following shock wave lithotripsy to aid the stone passage.
Other Name: Tamsulosin
Placebo Comparator: Sugar pill
Patients on this arm will be given a sugar pill to be taken for one month following their shock wave lithotripsy procedure.
Drug: Sugar pill
Comparable sugar pills will be given to the placebo group to take daily for one month following shock wave lithotripsy to aid stone passage.
Other Name: Placebo pill

Detailed Description:

Placebo blinded study examining the effects of Flomax on stone passage rates following SWL.
