Trial summary

Flexible ureteroscopy is a recent procedure to treat renal stone. Extracorporeal shockwave lithotripsy was the gold standard treatment for calculi between 5 and 20 mm. In literature, the two procedures are available to treat these stones with a good stone free rate. Read more about this study

About this study

Official title: Flexible urétéroscopy Versus Extracorporeal Shockwave Lithotripsy in 5 to 20 mm Renal Calculi, Efficacity Prospective Randomized Trial

Flexible ureteroscopy is a recent procedure to treat renal stone. Extracorporeal shockwave lithotripsy was the gold standard treatment for calculi between 5 and 20 mm. In literature, the two procedures are available to treat these stones with a good stone free rate. There is no prospective randomized study comparing these two treatments. Our study will define with a good level of evidence which technique is the best with regard to the stone free rate, secondary procedure rate and adverse effect.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • flexible ureteroscopyProcedure or surgery

    Flexible ureteroscopy will be use for 120 min max to treat renal stone. Laser, access sheath, baskets can be use to perform the technique.

  • extracorporeal shockwave lithotripsyProcedure or surgery

    The lithotriptor is use with 1,1 Hz frequency and stop when patient get 1000 joules of energy or if there is a problem with tolerance of this treatment or if stone is broken

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Stone free rate

    Rate of stone free patient or patient with residual fragment ≤ 3 mm, 3 months after the treatment evaluated, will be compare. This outcome is measured with a tomodensitometry and compares with pre treatment exams.

    Measured: Three months

Secondary outcomes (4)
  1. Stone free rate in weight's sub group

    Each arm wil be divise in 3 sub group based on body mass index (20 to 25, 25 to 30, 30 to 35). We'll compare rate of efficacity in each sub group

    Measured: 3 months

  2. Stone free rate in sub group depending on stone diameters

    Each arm wil be divise in 3 sub group based on calculi diameter (5 to 10mm, 10 to 15 and 15 to 20). We'll compare rate of efficacity in each sub group

    Measured: 3 months

  3. Secondary procedure rate

    In each arm will be evaluate rate of secondary procedure needed to have the best stone free rate

    Measured: 3 months

  4. Serious and non serious adverse events

    In each arm will be evaluate rate of adverse event, type, severity.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing flexible ureteroscopy and extracorporeal shockwave lithotripsy in people with Extracorporeal Shockwave Lithotripsy, Flexible Ureteroscopy, run by Hospices Civils de Lyon at 1 site in France.

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 5 inclusion and 6 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 28 May 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 France. 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: Three months). 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 NCT01604304, 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 28 May 2019.
