Answer

Measurement of postvoid residual urine volume, using either a bladder ultrasonography or urethral catheter, may be a part of the evaluation for urinary incontinence of patients with apparent failure to empty the bladder completely. If the PVR urine volume is high, the bladder may be acontractile or the bladder outlet may be obstructed. Both of these conditions cause urinary retention from overflow incontinence. Go to Urodynamic Studies for Urinary Incontinence for more information on this topic.
