Sponsor:	St. Michael's Hospital, Toronto
Collaborator:	Sanofi-Aventis
Information provided by:	St. Michael's Hospital, Toronto
ClinicalTrials.gov Identifier:	NCT00583258

Purpose

Patients who present for the first time to Emergency Room with renal colic due to a distal ureteral calculus (as diagnosed with spiral CT scan and KUB) will be randomized to receive Xatral 10mg po once a day or placebo once discharged from the ER. The purpose of this study is to assess if patients treated with Xatral will have a higher spontaneous passage rate of their ureteral stone than those treated with placebo.
