Other tests

  • Flow rate - Useful in the initial assessment and to help determine the patient’s response to treatment

  • PVR urine volume - Used to gauge the severity of bladder decompensation; it can be obtained invasively with a catheter or noninvasively with a transabdominal ultrasonic scanner

  • Pressure-flow studies - Findings may prove useful for evaluating for BOO

  • Urodynamic studies - To help distinguish poor bladder contraction ability (detrusor underactivity) from BOO

  • Cytologic examination of the urine - May be considered in patients with predominantly irritative voiding symptoms
