Design outcomes

Primary

MeasureTime frame
The study has a primary clinical and a primary economic outcome reflecting the multidimensional nature of the possible effects the intervention may have. Clinical: Clearance of ureteric stones operationally defined as ?no further intervention required to facilitate stone clearance? up to 6 months from randomisation. Economic: Incremental cost per quality adjusted life years (QALYs) gained at 6 months from randomisation. QALYs are based on the responses to the EQ-5D.

Secondary

MeasureTime frame
Patient-reported, measured at pre and 1 week post intervention, 8 weeks and 6 months post randomisation: 1. Severity of pain measured by the Numeric Rating scale (NRS) 2. Generic health profile measured by the SF-12 (8 weeks and 6 months only) 3. Health status measured by the EQ5D 4. Use of analgesia 5. Acceptability of received procedure (8 weeks and 6 months only) Clinical: Further interventions received, complications up to 6 months post randomisation Economic: NHS primary and secondary care use and costs up to 6 months, patient costs; incremental cost per surgical interventions averted.
