Study design	Randomised, double-blind, placebo-controlled, multi-centre trial.
Secondary study design	Randomised controlled trial
Study type	Participant information sheet
Scientific title
Study objectives	Can tamsulosin, an alpha-1-adrenergic antagonist, be used in uncomplicated renal colic to improve spontaneous ureteric calculus passage rates.
Ethics approval(s)	1. Approval for the lead centre: Central and South Bristol Research Ethics Committee. Date of approval: 24/09/2004 (ref: 04/Q2006/88). All other centres obtained approval before recruitment of participants. 2. Medicines and Healthcare products Regulatory Agency (MHRA). Approval expected in May 2008.
Health condition(s) or problem(s) studied	Urological and Genital Diseases: Acute renal colic
Intervention	As of 28/03/2013 the trial status was changed to 'stopped' as the trial was closed in January 2011 due to recruitment issues. Please note that, as of 11/04/2008, the anticipated start and end dates of this trial were updated from 01/06/2005 and 01/04/2007 to 01/05/2008 and 31/05/2010. This study is proposed to be a prospective, randomised double blind placebo controlled clinical trial. The patients will be randomly allocated to receive tamsulosin or placebo for a maximum of 6 weeks during conservative treatment of renal colic. Patients will be regularly monitored for side effects, stone passage and analgesic use during this time period.
Intervention type	Drug
Phase	Not Specified
Drug / device / biological / vaccine name(s)	Tamsulosin
Primary outcome measure(s)	Primary outcome measures amended as of 11/04/2008: 1. Spontaneous stone passage within 6 weeks 2. Early intervention due to complications Primary outcome measures provided at time of registration: 1. The percentage of calculi passed spontaneously within 6 weeks 2. The mean time to spontaneous passage 3. The mean use of analgesia in the form of diclofenac (recommended first line analgesic)
Key secondary outcome measure(s)	Added as of 11/04/2008: The following will be assessed at the end of the trial, i.e. time of stone passage or 6 weeks if stone not passed: 1. Percentage of calculi passed spontaneously within six weeks 2. Mean time to spontaneous passage 3. Mean use of analgesia in the form of diclofenac
Completion date	31/05/2010
Reason abandoned (if study stopped)	Participant recruitment issue

Eligibility

Participant type(s)	Patient
Age group	Not Specified
Sex	Not Specified

Key inclusion criteria	The total sample size required to produce statistically significant results is 206 patients (103 to receive placebo). All patients with renal colic with a visible calculus on X-ray which has been confirmed to be present within the ureter on intravenous urogram (IVU) will be asked to participate.
Key exclusion criteria	Patients will be excluded if pregnant, symptoms present for >14 days, evidence of infection or if they are already receiving treatment with tamsulosin or other calcium channel blocker.
