• Urinary retention (spinal cord compression or trauma)

  • Loss of awareness of bladder distension (damage to the frontal lobe as in frontal tumors, bifrontal subdural haematomas)

  • Frequency, urgency and urge incontinence (damage to the pons or spinal cord resulting in an upper motor neuron lesion)

  • Overflow incontinence (damage to the pudendal nerve leading to flaccid paralysis of the detrusor muscle of the bladder, resulting in a lower motor neurone lesion)
