Key content Indications for urodynamic investigations include urinary tract symptoms such as urge incontinence, stress urinary incontinence (SUI) and neurological urinary incontinence. Components of urodynamic testing include a physical assessment along with representative uroflowmetry with post‐void residual (PVR), transurethral cystometry and a pressure‐flow study. It is important for clinicians to understand key physiological measurements and parameters of lower urinary tract function. There are many factors to consider when interpreting results from urodynamic investigations, and it is vital for documentation to be accurate and methodical.Learning objectives To understand the key indications and components of urodynamics and how to define a clear question prior to starting investigations. To learn accepted physiological parameters for lower urinary tract functions and apply these to a concise method of interpreting urodynamic results. To acknowledge the limitations of an investigation when attempting to reproduce pathology in an artificial environment.Ethical issues Should all women undergoing an incontinence procedure have urodynamic investigations? Who to believe – the patient or the test?
