uroflowmetry
Pronunciation: yur-oh-flow-MET-tree
Non-invasive test measuring urinary flow rate and voiding patterns to assess bladder function and outlet obstruction in children.
Full Definition
A diagnostic urodynamic study that measures the rate and pattern of urine flow during voiding, providing objective assessment of lower urinary tract function. The test records flow rate (measured in mL/second), voided volume, and voiding time to generate characteristic flow curves. In pediatric patients, uroflowmetry helps identify bladder outlet obstruction, detrusor dysfunction, or incomplete bladder emptying. Normal flow patterns vary by age and gender, with children typically showing bell-shaped curves. Abnormal patterns may indicate neurogenic bladder, anatomical obstruction, or dysfunctional voiding requiring further evaluation.
Usage
Usage note: May be abbreviated as 'uroflow' in clinical notes; specify pediatric normal values when interpreting.
In Context
- "Uroflowmetry demonstrated a plateau pattern consistent with bladder outlet obstruction." — Diagnostic test report
- "Normal uroflowmetry results ruled out significant voiding dysfunction in this patient." — Clinical evaluation
