  1. Data expressed as number (%) or mean ± standard deviation. Analyses by Student t test for continuous data or Chi Square test for 2 × 2 categorical datasets
  2. aSatisfactory micturition is defined as residual bladder volume by ultrasound scan < 150 ml
  3. bVoided urine retrieved from receptacle and measured with a calibrated volume measurement jug
  4. cUltrasound formula for bladder content: volume = 0.52 x h (height) x d (depth) x w (width)
  5. dUnsatisfactory micturition (failed micturition attempt) is defined as residual bladder volume by ultrasound scan ≥150 ml
