Abstract

The position of invasive urodynamic testing (IUT) in diagnostic pathways for urinary incontinence is unclear, and systematic reviews have called for further trials evaluating clinical utility. The objective of this study was to inform the decision whether to proceed to a definitive randomised trial of IUT compared to clinical assessment with non-invasive tests, prior to surgery in women with stress urinary incontinence (SUI) or stress-predominant mixed urinary incontinence (MUI). A mixed methods study comprising a pragmatic multicentre randomised pilot trial, a qualitative face-to face interview study with patients eligible for the trial, an exploratory economic evaluation including value of information study, a survey of clinicians' views about IUT, and qualitative telephone interviews with purposively sampled survey respondents. Only the first and second of these elements are reported here. Trial participants were randomised to either clinical assessment with non-invasive tests (control arm) or clinical assessment with non-invasive tests plus IUT (intervention arm). The main outcome measures of these feasibility studies were confirmation that units can identify and recruit eligible women, acceptability of investigation strate...Continue Reading
