The bladder outlet behaves like a tap: obstruction is resistance at the valve, not weakness in the pump behind it

Bladder Outlet Obstruction: The Pressure-Flow Diagnosis

Bladder outlet obstruction is the diagnosis a flow rate cannot make: low flow means a blocked outlet or a weak detrusor, and only pressure-flow separates them.

Uroflowmetry Interpretation: Reading Qmax and Flow Curves

Uroflowmetry interpretation for clinicians: read flow curve, Qmax, and voided volume against the bladder diary and PVR, because a low Qmax is ambiguous.
