Incontinence is the loss of voluntary control over you urinary functions.
There are six main types of urinary incontinence:

• Stress
  Losing urine involuntarily during certain physical activities: coughing, laughing or sneezing; lifting; walking or performing other forms of exercise; moving to get up from a chair or out of bed.



• Urge
  Inability to control the sudden urge to urinate. A large amount of urine may be released. Urge incontinence may occur after a sudden change in position or activity.



• Mixed
  A mixture of stress and urge incontinence.



• Overflow
  Failure of the bladder to empty normally. The bladder remains at least partially full, and small amounts of urine are leaked on a nearly continuous basis.



• Neurogenic
  Related to defects in the nervous system, which conducts urination signals between the bladder and the brain. Patients may have severe, total incontinence.



• Post-prostatectomy
  Occuring after prostate surgery; may take the form of stress and/or urge incontinence.
