      2. Associated with strong sense of urinary urgency; urinary frequency and nocturia may be present
      3. Caused be detrussor overactivity and more commonly associated with CNS or spinal cord disorders
      4. Example Causes: CVA, Cystitis, Bladder Cancer, Bladder stones
    2. Stress Incontinence (Loss of pelvic support at Urethra)

Urinary Incontinence (C0042024)

Definition (MEDLINEPLUS)

Urinary incontinence (UI) is loss of bladder control. Symptoms can range from mild leaking to uncontrollable wetting. It can happen to anyone, but it becomes more common with age. Women experience UI twice as often as men.

Most bladder control problems happen when muscles are too weak or too active. If the muscles that keep your bladder closed are weak, you may have accidents when you sneeze, laugh or lift a heavy object. This is stress incontinence. If bladder muscles become too active, you may feel a strong urge to go to the bathroom when you have little urine in your bladder. This is urge incontinence or overactive bladder. There are other causes of incontinence, such as prostate problems and nerve damage.

Treatment depends on the type of problem you have and what best fits your lifestyle. It may include simple exercises, medicines, special devices or procedures prescribed by your doctor, or surgery.

Definition (NCI_NCI-GLOSS) Inability to hold urine in the bladder.
Definition (NCI_CTCAE) A disorder characterized by inability to control the flow of urine from the bladder.
Definition (NCI) Inability to control the flow of urine from the bladder.
Definition (CSP) failure of voluntary control of the vesical and urethral sphincters, with constant or frequent involuntary passage of urine.
Definition (MSH) Involuntary loss of URINE, such as leaking of urine. It is a symptom of various underlying pathological processes. Major types of incontinence include URINARY URGE INCONTINENCE and URINARY STRESS INCONTINENCE.
