III. Mechanism

  1. Assess urine outflow obstruction

IV. Normal Urodynamic Measurements

  1. Total Voiding Time
    1. Normal time to void 100 ml: less than 10 seconds
    2. Normal time to void 400 ml: less than 23 seconds
  2. Mean Flow Rate
  3. Time to Peak Flow
    1. Less than one third of Total Voiding Time
  4. Peak Flow Rate
    1. Below mean flow rate per Bladder volume (<2 S.D.)

V. Interpretation: Signs of Benign Prostatic Hyperplasia

  1. Prolonged Total Voiding Time
  2. Decreased Peak Urine Flow rate
