Urodymanic, Uroflowmetry, Total Voiding Time, Peak Urine Flow

  • Indications
  1. Benign Prostatic Hyperplasia
  • Mechanism
  1. Assess urine outflow obstruction
  • 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.)
  1. Prolonged Total Voiding Time
  2. Decreased Peak Urine Flow rate
