Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Shock wave lithotripsy - approximately 3000 shock waves focussed onto stone from an external energy source. Can be performed without any anaesthetic taking about 50 minutes.
Ureterorenoscopic stone removal - insertion of a fine flexible telescope into the renal tract through the urethra and destruction of stone with a laser. Requires general anaesthetic and takes about 90 minutes.
Percutaneous nephrolithotomy - creating a tract through the skin to the kidney through which a telescope is inserted, the stone broken up with various energy sources and the fragments removed. Requires a general anaesthetic and takes about 1 hour.
Patients may undergo repeated treatment or offered one of the other alternatives until they are free of stones.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients encountered with inclusion criteria will be invited into trail with information sheet. If enrolled will be randomly allocated into one of the 3 arms
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated randomisation overseen by our statistician who will be "off-site" as a means of allocation concealment.
Masking / blinding
Blinded (masking used)

Other design features
Stone free rates will be assessed by a radiologist blinded to the actual treatment
Phase

Efficacy
Statistical methods / analysis
Mixture of parametric and non-parametric analyses depending on data variability. All statistics to be designed and performed by university affiliated independent statistician
