A Randomized Study of Whether Alfuzosin(Xatral) Helps in the Passage of Kidney Stones

This study has been withdrawn prior to enrollment.
Information provided by (Responsible Party):
St. Michael's Hospital, Toronto Identifier:
First received: December 20, 2007
Last updated: July 30, 2015
Last verified: July 2015
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.

Condition Intervention
Kidney Stones Drug: Alfuzosin (Xatral) Drug: Placebo Alfuzosin

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blinded Placebo-Controlled Trial of Alfuzosin (Xatral)in the Management of Distal Ureteral Calculi

Further study details as provided by St. Michael's Hospital, Toronto:

Primary Outcome Measures:
  • The primary outcome will be Cox proportional hazards survival analysis of stone passage over time [ Time Frame: 4 weeks ]

Secondary Outcome Measures:
  • Secondary outcomes will be stone passage rates, pain scores, intervention rates, hospitalization rates and complication rates [ Time Frame: 4 weeks ]

Enrollment: 0
Study Start Date: October 2007
Study Completion Date: October 2009
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A Drug: Alfuzosin (Xatral)
