Why urodynamics may be considered
- Urinary urgency, frequency or leakage
- Difficulty emptying the bladder or urinary retention
- Mixed or unexplained urinary symptoms
- Symptoms that have not improved with initial treatment
- Planning selected bladder or continence procedures
What the test can assess
- Bladder pressure while filling and passing urine
- How much the bladder can comfortably hold
- Urinary flow and bladder emptying
- Whether leakage occurs during filling or coughing
- How the bladder muscle and outlet work together
What to expect
- The testing team will explain preparation and consent
- Small catheters may be used to measure bladder and abdominal pressure
- The bladder is filled gradually while symptoms are recorded
- You may be asked to cough or pass urine during the test
- Results are interpreted alongside your symptoms and other investigations
How this fits your care: Urodynamics is not required for every bladder symptom. A consultation helps determine whether the result is likely to change treatment planning.
Discussing the next step
Mr Syed Ali Shahzad can review your symptoms, previous results and imaging before explaining whether this investigation is appropriate and how the result may affect treatment planning. Tests are arranged through the relevant hospital pathway.
