Urinary CalculiPhase 3NCT00388271
Use of Alfuzosin in Stone Treatment With ESWL
A Phase 3 study testing Alfuzosin (Xatral) and standard treatment in people with Urinary Calculi, run by Singapore General Hospital at 1 site in Singapore.
Trial summary
Urinary tract stones may form in the kidneys or along the ureteric tracts and when left untreated, may result in complications such as pain, bleeding, infection and obstruction. ESWL (extra-corporeal shock wave lithotripsy) has been shown to be an effective and safe method of treatment for kidney and ureteric stones… Read more about this study

About this study
Official title: To Investigate if Alpha-blocker Therapy (Alfuzosin) Increases Stone Free Rates and Improves Pain Control After ESWL (Extra-corporeal Shock Wave Lithotripsy) for Renal and Ureteric Stones.
Urinary tract stones may form in the kidneys or along the ureteric tracts and when left untreated, may result in complications such as pain, bleeding, infection and obstruction. ESWL (extra-corporeal shock wave lithotripsy) has been shown to be an effective and safe method of treatment for kidney and ureteric stones in-situ. In our centre, ESWL is done on an outpatient basis with oral pain killers in the weeks following treatment. Patients are also instructed to increase their fluid intake during this period to expedite the clearance of stone fragments. There have been studies to show that pain caused by stones is due to smooth muscle spasm along the ureters, possibly mediated by alpha-receptors. Alpha-blockers have been shown to improve the expulsion of stones and also improve pain relief when used alone, or together with ESWL treatment. In our study, we seek to investigate if alpha-blocker therapy (Alfuzosin) increases stone free rates and improves pain control after ESWL for renal and ureteric stones. The potential benefits include a higher rate of stone clearance and better pain control

Urinary tract stones may form in the kidneys or along the ureteric tracts and when left untreated, may result in complications such as pain, bleeding, infection and obstruction. ESWL (extra-corporeal shock wave lithotripsy) has been shown to be an effective and safe method of treatment for kidney and ureteric stones in-situ. In our centre, ESWL is done on an outpatient basis with oral pain killers in the weeks following treatment. Patients are also instructed to increase their fluid intake during this period to expedite the clearance of stone fragments. Alpha1-adrenergic blockers have been shown to improve stone free rates in renal stones and lower ureteric stones. Tamsulosin has been the agent most commonly investigated. There have been no studies done to study the effectiveness of Alfuzosin in stone treatment. Alfuzosin has been shown to be effective in treating benign prostatic hypertrophy, and has a good safety profile. Deliveliotis et al has shown that alfuzosin improves symptoms and quality of life in patients with double-J stents.
This is a prospective, randomised, double-blind, placebo-controlled study involving patients undergoing ESWL for renal and ureteric stones. Exclusion criteria applies (please see below). The patients will be randomised into 2 groups: study VS control. Randomisation is done by using a computer generated list with block randomisation, assigning consecutive patients to either treatment arms. Our standard treatment is intravenous pethidine 50mg and intravenous maxolon 10mg at the onset of the ESWL session, followed by oral analgesics- NSAIDs with a gastroprotective agent. For this study, we will standardise all to oral naproxen 550mg BD with oral omeprazole 20mg BD. The study group will receive the standard treatment, with oral alfuzosin 10mg ON for 1 month, while the control group will receive a placebo. Patients will be given a diary in which to chart their pain scores, use of analgesics, episodes of pain, passage of stones, side-effects of the medications and complications of treatment. At the end of one month, all patients will be called back for review. Stone free status is ascertained with an X-ray, and the diary will be collected for further analysis.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Alfuzosin (Xatral) and standard treatment in people with Urinary Calculi, run by Singapore General Hospital at 1 site in Singapore.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 10 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Reduction in pain score (time frame: 1 month). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00388271, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2017; AzTrials last refreshed its copy on 8 Nov 2026.
