What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SWLProcedure or surgery
Also called ESWL
Shock wave lithotripsy
| Study group | Role | What they receive |
|---|---|---|
| Ultraslow shock wave lithotripsy (SWL) | Active comparator | SWL at ultraslow rate of 30 SW/min. Power ramping at the first 100 SW from 6 to 18 kv followed by safety pause for two minutes then power ramping from 18 to 22kv during the second 100 SW followed by safety pause for another two minutes.
The rest of the session at 22kv (full power). Receives: Procedure: SWL |
| Slow power-ramping SWL | Active comparator | SWL at a slow rate of 60 SW/min. Power ramping from 6 - 10 kv during the first 500 SW then from 11 - 14 kv during the second 500 SW then from 15 - 18 kv during the following 500 SW then from 19 - 22 kv during the remaining 1000 - 1500 SW. Receives: Procedure: SWL |
What is being measured
The primary outcome is the main question the study is designed to answer.
stone free rate
Complete clearance of stones in addition to clinically insignificant residual fragments
Measured: 3 months following last session of SWL
Secondary outcomes (1)
Complications rate
Comparison of rate of complications in both groups
Measured: 3 months following last session of SWL

Questions about this trial
What is this clinical trial studying?
A study testing SWL in people with Ureteric Stone, run by Cairo University at 1 site in Egypt.
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 3 inclusion and 9 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: finished, as of the sponsor's last update on 10 Dec 2019. 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 Egypt. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
stone free rate (time frame: 3 months following last session of SWL). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 Dec 2019.
