The purpose of this study is to determine the efficacy of the α-adrenergic antagonist tamsulosin in the treatment of adult emergency department (ED) patients with ureteral colic secondary to lower ureteral calculus. We hypothesize that there will be no difference in outcomes for subjects treated with and without tamsulosin.

Condition Intervention
Ureteral Calculi
Drug: tamsulosin
Drug: Standard therapy with ibuprofen and oxycodone.

Study Completion Date: November 2007
Primary Completion Date: November 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: I
Subjects randomized to the experimental group receive ibuprofen, oxycodone, and tamsulosin 0.4 mg orally daily for ten days.
Drug: tamsulosin
Tamsulosin 0.4 mg orally daily for ten days.
Other Name: Flomax
Standard therapy arm: subjects randomized to standard therapy receive ibuprofen and oxycodone alone.
Drug: Standard therapy with ibuprofen and oxycodone.
Oxycodone: 5mg, one to two tablets every four to six hours as needed for pain. Ibuprofen: 800 mg, one three times a day with food as needed for pain.

Detailed Description:
This prospective, randomized controlled trial seeks to compare outcomes for adult emergency department patients with lower ureteral calculus. Subjects will be randomized to receive treatment with ibuprofen and oxycodone alone (standard therapy) or standard therapy plus tamsulosin 0.4mg orally once daily for ten days.
