Common Bladder Management Programs

Managing Bladder and Bowel Issues in MS

There are three common types of bladder emptying:

  • Intermittent catheterization. A thin, hollow, flexible tube is inserted into the urethra, allowing the urine in the bladder to drain out.
  • Indwelling catheter. A permanent catheter is inserted into the bladder, and a balloon keeps it in place.
  • External condom catheter. This catheter for me is attached to a condom that keeps the catheter in place and collects urine.

Treatments For Bladder Problems

Once the cause of your bladder problem has been found, you will be offered advice and treatment. These can include:

  • Drinking plenty of fluids. Strong, concentrated urine irritates your bladder. This makes feelings of urgency worse, can cause leakage and also bladder infections. Caffeine can also stimulate urine production so you may be advised to reduce your caffeine intake.

  • Bladder training reduces urgency and frequency by gradually teaching your bladder to hold more urine. This is done by making regular visits to the toilet, and gradually extending the time between visits until your bladder learns how to hold on.

  • Pelvic floor exercises help strengthen muscles so that they provide support. This will help improve bladder control and improve or stop leakage of urine.

  • Electrical stimulation devices, which can be inserted in either the vagina or the anus to stimulate and strengthen the muscles that control the bladder.

  • Using medication to reduce feelings of urgency and frequency, or reduce the amount of urine your body makes.

  • Weight loss often improves bladder control in the longer term.

  • Stopping smoking: coughing makes bladder leakage worse. Stopping smoking can help.

What Spinal Nerves Affect The Bladder

The lower urinary tract is innervated by 3 sets of peripheral nerves: pelvic parasympathetic nerves, which arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra lumbar sympathetic nerves, which inhibit the bladder body and excite the bladder base and urethra and pudendal nerves,

. Furthermore, what nerve controls the bowels?

The sacral nervesSome of these sacral nerves go to the rectum, levator ani muscle, and external sphincter muscles, controlling their activities. Two key sacral nerves that are vital to the functioning of the bowel are the pudendal nerve and the pelvic splanchnic nerve.

Beside above, what causes loss of bladder and bowel control? Many conditions may affect the nerves and muscles that control the bladder and bowel. Bladder incontinence can be caused by things such as: Holding urine in too long , which can damage the bladder. Having to urinate many times during the day and night, often urgently

Regarding this, what nerves control the bladder?

Neural Control of the Lower Urinary Tract

  • Pelvic parasympathetic nerves: arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra.
  • Lumbar sympathetic nerves: inhibit the bladder body and excite the bladder base and urethra.
  • Pudendal nerves: excite the external urethral sphincter.

Can your bowel affect your bladder?

Constipation can affect bladder control and urinary continence. An over-full bowel can press on the bladder, reducing the amount of urine it can hold or making you feel like to need to pass urine urgently. Constipation can also affect your pelvic floor muscles.

Some common treatments are:

  • Changes in food or drink. Increasing your fiber intake can help manage diarrhea and constipation. Drinking plenty of fluids can also ease constipation. Not drinking fluids at certain times can help manage overactive bladder and urinary incontinence.

  • Exercises. Kegel exercises can strengthen the sphincter muscles and pelvic floor. This can help you have better control.

  • Medicines. Some medicines can help control bowel incontinence. Antidiarrheal medicines can help manage diarrhea. And medicine can help bladder muscles relax to give you better control.

  • Keeping a bathroom schedule. Setting a regular schedule for using the toilet can give you better control. This includes attempting to urinate or move your bowels at the same time each day.

  • Electrical stimulation. This therapy can stimulate damaged nerves. This may give you better muscle control in your bladder or bowel.

  • Surgery. In rare cases, you may need surgery to repair damage to muscles or nerves.

Your healthcare provider will work with you to create a treatment plan.

Neural Circuit Control Of Reflex Micturition

While we understand very little about the central neurologic basis of continence, more is known about the basic neural circuit controlling the micturition reflex. In the 1920s, J. F. Barrington produced brainstem lesions in cats. Combining these lesions with behavioral monitoring and urodynamics, he found a small region in the dorsal pons that, when lesioned, caused urinary retention . This region, previously referred to as the pontine micturition center, is now known as Barringtons nucleus . Bar neurons project axons to the sacral spinal cord and coordinate bladder contraction with EUS relaxation . As the bladder fills with urine, mechanosensors in the bladder wall progressively activate an ascending pathway through the sacral spinal cord and through relay neurons in the midbrain periaqueductal gray , which then trigger reflex activation of Bar neurons .

What Are The Treatments For Urine Retention

Urine retention may occur either because the bladder wall muscles cannot contract or because the sphincter muscles cannot relax.

Catheter. A catheter is a thin tube that can be inserted through the urethra into the bladder to allow urine to flow into a collection bag. If you are able to place the catheter yourself, you can learn to carry out the procedure at regular intervals, a practice called clean intermittent catheterization. Some patients cannot place their own catheters because nerve damage affects their hand coordination as well as their voiding function. These patients need to have a caregiver place the catheter for them at regular intervals. If regular catheter placement is not feasible, the patients may need to have an indwelling catheter that can be changed less often. Indwelling catheters have several risks, including infection, bladder stones, and bladder tumors. However, if the bladder cannot be emptied any other way, then the catheter is the only way to stop the buildup of urine in the bladder that can damage the kidneys.

Urethral stent. Stents are small tube-like devices inserted into the urethra and allowed to expand, like a spring, widening the opening for urine to flow out. Stents can help prevent urine backup when the bladder wall and sphincter contract at the same time because of improper nerve signals. However, stents can cause problems if they move or lead to infection.

What Are The Treatments For Overactive Bladder

The treatment for a bladder control problem depends on the cause of the nerve damage and the type of voiding dysfunction that results.

In the case of overactive bladder, your doctor may suggest a number of strategies, including bladder training, electrical stimulation, drug therapy, and, in severe cases where all other treatments have failed, surgery.

Bladder training. Your doctor may ask you to keep a bladder diary-a record of your fluid intake, trips to the bathroom, and episodes of urine leakage. This record may indicate a pattern and suggest ways to avoid accidents by making a point of using the bathroom at certain times of the day-a practice called timed voiding. As you gain control, you can extend the time between trips to the bathroom. Bladder training also includes Kegel exercises to strengthen the muscles that hold in urine.

Drug therapy. Different drugs can affect the nerves and muscles of the urinary tract in different ways.

Additional drugs are being evaluated for the treatment of overactive bladder and may soon receive FDA approval.

Pelvic Floor Muscle Exercises

You Are Not Alone Find Relief for Bowel & Bladder Control Problems

The pelvic floor is layers of muscles that stretch from the pubic bone to the coccyx and then from side to side. These muscles help to support the bladder and bowel plus the womb in women. These muscles can become weak through trauma such as childbirth or surgery, changing hormones, persistent coughing, chronic constipation or even damage caused to the brain such as from a stroke. When these muscles become slack it can weaken the sphincter muscle to the rectum or bladder allowing the involuntary passing of stool or urine.

Bladder Control Problems & Nerve Disease

For the urinary system to do its job, muscles and nerves must work together to hold urine in the bladder and then release it at the right time. Nerves carry messages from the bladder to the brain to let it know when the bladder is full. They also carry messages from the brain to the bladder, telling muscles either to tighten or release. A nerve problem might affect your bladder control if the nerves that are supposed to carry messages between the brain and the bladder do not work properly.

What Part Of The Spinal Cord Controls The Bladder

Lower back and leg activity is controlled here. The lowest part of the spinal cord is the sacral spinal cord. Bladder function, bladder and bowel external sphincters, sexual functions , and some leg muscles are the domain of the sacral spinal cord.

Also to know is, what spinal nerve controls bladder?

Pelvic parasympathetic nerves: arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra. Lumbar sympathetic nerves: inhibit the bladder body and excite the bladder base and urethra. Pudendal nerves: excite the external urethral sphincter.

Secondly, can spinal problems cause bladder problems? Compression of these nerves due to lumbar stenosis can lead to neurogenic bladder dysfunction and present as urinary issues such as frequency, urgency and lack of control. Pain and the other symptoms that are normally associated with lower back issues are difficult enough to deal with.

Beside this, what level of spinal cord injury causes urinary incontinence?

Injury to the spinal cord at T10-L2 will result in urinary incontinence and an overactive bladder. With injury above the sacral micturition level, the detrusor muscle will spasm and DSD can occur. This can result in a functional obstruction that may damage the upper renal system.

Incontinence After Brain Injury: Why It Occurs And How To Manage It

Elizabeth Denslow, OTR/L Flint Rehab

Incontinence refers to the involuntary loss of bladder and/or bowel control. It is a common secondary effect of brain injury that can affect ones independence and quality of life. Fortunately, with the right management interventions, incontinence after brain injury can often be improved.

To help you understand incontinence after brain injury, this article will discuss:

Bladder And Bowel Incontinence

Autonomic innervation of the urinary bladder (see text for ...

Incontinence is a loss of control of a person’s bowels or bladder which can cause accidental leakage of body fluids and waste. Incontinence can be more than a physical problem. It can disrupt your quality of life if its not managed well.

Fear, anxiety, and anger are common feelings for people dealing with incontinence. You may avoid being intimate or having sex because you are afraid of urine, gas, or stool leakage. Fear of having an accident may keep you from being physically active, enjoying hobbies, or spending extended time outside your home.

Both men and women can have incontinence during and after surgery or some other treatments for cancer. Incontinence can also occur because of other non-cancer medical conditions. Be sure to talk to your health care team if you have difficulty controlling urination or bowels. Talking about incontinence can be embarrassing, but being open and honest with your health care team can help manage it.

  • Faecal incontinence: uncontrolled bowel movement. This can be caused by damage to the part of the brain controlling the bowel. It can also happen if you cant get to the toilet in time, or if you have diarrhoea or constipation.

  • Constipation with overflow: large stools can get stuck and block the bowel. Liquid stools may flow around it causing watery stools to leak.

  • Faecal impaction: dry, hard stools collect in the bowel. They can press on your bladder and make you feel you need to empty it more often or they can make it more difficult to empty your bladder.

Living With Bowel Or Bladder Incontinence

There is no single, right way to cope with bladder or bowel incontinence. The challenge is to find what is best for your situation, so you can get the help you need and return to a normal daily life. Talk with your health care team if you notice a change in bowel or bladder habits, and about the best ways to manage incontinence, if it is a problem. You might find it helpful to talk with other people who are dealing with incontinence, too. Ask a member of your cancer care team about support groups in your area.

Here are some things you can do that may help make incontinence less of a problem:

  • Empty your bladder every 3 to 4 hours while awake, to avoid accidents.
  • Empty your bladder before bedtime or before strenuous activity.
  • Limit drinks with caffeine, or and avoid alcohol and citrus juices, which can irritate the bladder and make you have to go more often.
  • Avoid hygiene products that may irritate you Women should avoid feminine spray or over-the-counter vaginal suppositories.
  • Because belly fat can push on the bladder, avoiding weight gain or losing needed weight sometimes helps improve bladder control.
  • Avoid tobacco use which can cause coughing and bladder irritation due to harmful substances in tobacco products.
  • Talk to your doctor about all medicines, vitamins, herbs, and supplements youre taking. Some may affect urine control.

Spinal Cord Injury And Bladder Function

The bladder maintains storage and release of urine through influences from the central nervous system. In the past, renal failure has been a leading cause of death in the SCI patient. With improved management of urological dysfunction in SCI patients, mortality has been greatly reduced. Specific objectives for a bladder management program entail efficient storage and emptying while maintaining low pressures and preventing overdistention of the bladder. These measures can prevent complications from high intravesicular pressure. It is to the patients benefit to maintain a bladder regimen that allows them to integrate into society. Urinary tract infections should be prevented.


Descending Inputs To Barringtons Nucleus

Men getting help for bladder and bowel control problems

BarESR1 neurons can trigger voiding and BarCRH neurons augment bladder contraction, but voluntary micturition control requires input from the forebrain. Many brain regions provide direct input projections to Bar, including the lateral hypothalamic area , medial preoptic area , bed nucleus of the stria terminalis , PAG, anterior cingulate cortex , prelimbic cortex, and primary and secondary motor areas . Recent experimental work has focused largely on excitatory inputs that promote voiding.

For example, Bar receives dense, excitatory input from both the PAG and the LHA. Glutamatergic input from both brain regions produces excitatory post-synaptic responses on both BarCRH and non-CRH neurons without preference for either subgroup . Optogenetically stimulating glutamatergic axons from the PAG causes immediate voiding with an incontinent phenotype mice void a small amount, immediately, when stimulated. Stimulating glutamatergic input from the LHA also led to voiding, often with a delay these mice produced fewer, larger voids. Bar also receives direct input from the mouse primary motor cortex , which could allow volitional initiation of voiding . It is not yet clear whether axons from any of these afferent sites selectively target one or the other Bar subpopulation.

What Is Neurogenic Bladder

Neurogenic bladder is when a problem in your brain, spinal cord, or central nervous system makes you lose control of your bladder. You may pee too much or too little. You could have symptoms of both overactive bladder and underactive bladder . You may not be able to fully empty it.

Itâs normal to have some stress and anxiety if you canât control when you urinate. Talk to your doctor about whatâs going on as soon as possible so you can start on a treatment to help manage your symptoms.

Practical Tips On Living Well With Incontinence

While it does involve extra thought and effort, with good advice and preparation, bladder and bowel problems can be managed discreetly as part of everyday life.

Planning ahead when you go out

Practical measures like planning access to toilets when you are out, and having a change of clothing and hygiene kit with you will help you manage in any situation.

The National Key Scheme , also known as the RADAR Scheme, provides keys to public disabled toilets designed for wheelchair access. The scheme is available to people with disabilities or health conditions seriously affecting their continence.

The Just Cant Wait Toilet Card is also free and available from the Bladder and Bowel Community. Showing this clearly and discretely allows you to access toilets anywhere, when you have an urgent need.

Find a routine that works for you

A daily routine of regular visits to the toilet, staying hydrated during the day and reducing the amount you drink just before bed time, will help to avoid accidents. An alarm can be used to schedule a visit to the toilet during the night, or you may prefer to try a moisture alarm on your bed, which will sound when wetness is detected. This is designed to wake you up so that you can finish emptying your bladder in the toilet.

You may wish to wear a silent vibrating alarm watch, which can be set to give a discreet reminder at regular intervals. A silent alarm also has advantages at night time if you wish to avoid disturbing others.
