Tamsulosin (Flowmax)is approved by the FDA for the treatment for enlarged prostate. Several studies regarding the use of Tamsulosin for the treatment of lower kidney stones have been carried out in the non-Emergency Department setting. This study will compare Tamsulosin 0.4 mg with placebo in regards to rate and time of stone passing and will also look at amount of pain. The purpose of this study is to compare the usefulness of Tamsulosin versus placebo on time to stone passage and pain relief in Emergency Department patients with kidney stones.
