Principles of Measurement of Urinary Flow

  • Richard Napier-HemyEmail author


Patients are notoriously poor at accurately reporting changes in their flow. Urinary flow rate estimation is relatively cheap and noninvasive. It should be used as first-line investigation of male patients with voiding dysfunction but has a less established role in women. It must be remembered that uroflowmetry is a measurement of flow only and that assumptions about detrusor function can only be inferred.
