Principles of Measurement of Urinary Flow
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.
