Types of Incontinence
Acute or Transient
Chronic or Persistent
Urinary
incontinence can be classified as acute or transient, and chronic or
persistent. You can also think of transient incontinence as a temporary,
treatable, and
reversible
problem. The onset of transient incontinence can be correlated to an
acute illness or exacerbation of a medical problem.
This
mnemonic from Dr. Neal Resnick is helpful to use when we are conducting
our individualized assessment of a patient/resident with new onset
incontinence. Before ordering a bag of adult briefs, evaluate to see if
any of these factors contributed to the onset of incontinence.
Identification of one or more of these factors can result in prompt
resolution of the problem.
This is a list of frequent reversible causes of incontinence.
Delirium
Infection
Atrophic
Vaginitis
Pharmaceuticals,
Psychological
Excessive
urine output
Restricted
or decreased Mobility
Stool
Impactions
In
addition to delirium, dehydration can contribute to incontinence. As the
urine becomes more concentrated, this irritates the urethra and bladder
causing increased frequency and incontinence. Hydrating the patient will
usually resolve the incontinence. Pharmaceuticals that can contribute to
incontinence include: diuretics, ACE inhibitors, Calcium Channel
blockers, sedatives, hypnotics, and anti-cholinergics to name a few--so
check the patient’s/resident’s medication administration record and
consult with your pharmacist. And don’t forget to look at caffeine and
alcohol use. Conditions like hyperglycemia, heart failure, hypercalcemia
and venous insufficiency contribute to increased urine production.
Constipation and/or fecal impaction can contribute to urinary retention
and urinary incontinence as well.
Persistent Urinary Incontinence
Persistent or chronic urinary incontinence can
be classified in the following ways. Knowing
what type of incontinence a patient has provides
us with useful information related to the timing
of the incontinent episode as well as any
precipitating factors prior to the episode.
Knowing the type can also help to quantify the
amount of urine lost. These, in addition to
other assessment findings, such as mobility and
activity level, mental status, and past medical
and surgical histories helps us select the most
appropriate and cost-effective management
products.
Functional
Stress
Urge or
Overactive Bladder
Mixed
Overflow
Functional incontinence
occurs when a person is unable, or in some cases
unwilling, to use the toilet. It happens as a
result of having a condition that impacts the
person’s ability to get around. This may be
related to joint problems like arthritis,
problems with gait and balance, fractures,
muscle weakness and dementia. Sometimes, we as
caregivers cause functional incontinence. Many
years ago (pre-OBRA-87), a 76 year old woman was
hospitalized for pneumonia. She was receiving IV
fluids at 125cc/hr and some IVPB antibiotics.
She also received some IVP Lasix. Her side rails
were up and her call light was across the room.
Is it any wonder that when the nursing
assistant heard her calling that her bed was
already wet?
Stress incontinence is a problem with the
urethra and the sphincter. Usually, small
amounts of urine are lost when there is a sudden
increase in intra-abdominal pressure which
occurs with sneezing, coughing, lifting or
getting out of bed. The pelvic floor muscles and
sphincters may become weak or damaged by giving
birth, straining to move one’s bowels due to
constipation, or with declining estrogen levels.
Urge or overactive bladder is associated
with the “gotta go right now” phenomena.
Moderate to large amounts of urine may be lost
at one time and associated symptoms include
frequency, nocturia and urgency. For some, a
trigger precedes the strong urge to void. This
may include: putting a key in the front door
lock, hearing water running, or washing dishes.
OAB occurs when the bladder muscle has
uninhibited, involuntary contractions when the
bladder is filling, which forces the urine into
the urethra. The person is unable to inhibit
these contractions which results in urine loss.
Mixed incontinence is a combination of
both stress and urge symptoms with variable
amounts of urine lost.
Overflow
incontinence occurs when the bladder can't
empty completely. Once pressure within the
bladder becomes high enough that urine dribbles
through the urethra. It can be associated with
diabetes, spinal cord injury or urethral
blockage which may be associated with BPH or
prostate cancer. The patient may complain of
trouble getting started, a weak urinary stream,
and dribbling after urination--or even a
constant leakage of small amounts of urine all
day long. They often say they feel their bladder
is never empty.
