Overactive Bladder (OAB)

 

Overactive bladder (OAB) is the name for a group of urinary symptoms. It is not a disease. The most common symptom is a sudden, uncontrolled need or urge to urinate. Some people will leak urine when they feel this urge. Another symptom is the need to pass urine many times during the day and night. OAB is basically the feeling that you’ve “gotta’ go” to the bathroom urgently and too much.

 

Leaking urine is called “incontinence”. Stress urinary incontinence (SUI), is another common bladder problem. It’s different from OAB. People with SUI leak urine while sneezing, laughing or doing other physical activities.

 

 

Key Statistics

As many as 30 percent of men and 40 percent of women in the United States live with OAB symptoms. Many people living with OAB don't ask for help. They may feel embarrassed. Many people either don't know how to talk with their health care provider about their symptoms, or they think there aren't treatments that can help.

 

The truth is there are many treatments that can help. Asking Dr. Tubre about it is the first step.

 

 

How OAB Can Affect Your Life

OAB can get in the way of your work, social life, exercise and sleep. Without treatment, OAB symptoms can make it hard to get through the day without many trips to the bathroom. You may not want to go out with friends or go far from home because you're afraid of being far from a bathroom. This makes many people feel lonely and isolated.

 

OAB may affect relationships with friends and family. It can disrupt your sleep and sex-life. Too little sleep will leave anyone tired and depressed. In addition, if you leak urine, you may develop skin problems or infections.

 

You don't have to let OAB rule your life. OAB can be controlled. If you think you have OAB, see Dr. Tubre.

 

 

The Truth About OAB

• OAB is not a normal part of getting older.
• OAB is not just part of being a woman.
• OAB is not just an issue with the prostate.
• OAB is not caused by something you did.
• Surgery is not the only treatment for OAB.
• There are treatments to help people manage OAB symptoms.
• There are treatments to help even minor OAB symptoms.

 

If you are bothered by OAB symptoms, then you should ask for treatment!

 

 

Symptoms

 

Urgency: The major symptom of OAB is a sudden, strong urge to urinate that you can't ignore. This "gotta go" feeling makes you fear you will leak if you don't get to a bathroom right away. You may or may not actually leak with this urge to go.

 

 

If you live with OAB, you may also:

 

• Leak urine or have “urge incontinence.” This means urine leaks when you feel the sudden urge to go. This isn’t the same as stress urinary incontinence or SUI . People with SUI leak urine when sneezing, laughing or doing other physical activities.
  
  
• Urinate frequently. You may need to go to the bathroom many times during the day. The number of times someone urinates varies from person to person. Many experts agree that going to the bathroom more than eight times in 24 hours is “frequent urination.”
  
  
• Wake up at night to pass urine. If you have to wake from sleep to go to the bathroom more than once a night, it’s a symptom of OAB or nocturia.

 

Causes

 

Normally, when your bladder is full of urine waste, your brain signals the bladder. The bladder muscles then squeeze. This forces the urine out through the urethra. The sphincter in the urethra opens and urine flows out. When your bladder is not full, the bladder is relaxed.

 

With a healthy bladder, signals in your brain let you know that your bladder is getting full or is full, but you can wait to go to the bathroom. With OAB, you can’t wait. You feel a sudden, urgent need to go. This can happen even if your bladder isn’t full.

 

If the nerve signals between your bladder and brain don’t work properly, OAB can result. The signals might tell your bladder to empty, even when it isn't full. OAB can also be caused when muscles in your bladder are too active. This means that the bladder muscles contract to pass urine before your bladder is full. In turn, this causes a sudden, strong need to urinate. We call this "urgency."

Risk Factors for OAB

• Neurologic disorders or damage to the signals between your brain and bladder
• Hormone changes
• Pelvic muscle weakness or spasms
• A urinary tract infection
• Side effects from a medication
• Diseases that affect the brain or spinal cord, like stroke and multiple sclerosis

 

If you think you have OAB, talk with Dr. Tubre. It’s important to learn why it’s happening so you can manage your symptoms.

 

 

How the Urinary Tract Works Normally

The urinary tract is the important system in our bodies that removes liquid waste (urine). It includes the organs that produce, store and pass urine. These are:

 

• Kidneys: two bean-shaped organs that clean waste from the blood and make urine.
• Ureters: two thin tubes that take urine from the kidney to the bladder.
• Bladder: a balloon-like muscular sac that holds urine until it’s time to go to the bathroom.
• Urethra: the tube that carries urine from the bladder out of the body. The urethra has a muscle called a sphincter that locks in urine.
• The sphincter muscle opens to release urine when the bladder contracts.

Diagnosis

 

After you talk about your symptoms, Dr. Tubre may do an exam right away. Or, they may refer you to a specialist, such as a urologist who can diagnose and treat OAB. Some urologists specialize in incontinence and OAB.

 

 

Medical History

 

Your exam will begin with questions. Your provider will want to understand your health history and experiences. You should tell them about the symptoms you have, how long you’ve had them, and how they’re changing your life. A medical history will include questions about your past and current health problems. You should bring a list of over-the-counter and prescription drugs you take. You should also tell your provider about your diet and about how much and what kinds of liquids you drink during the day and night.

 

 

Physical Exam

 

Your provider will examine you to look for something that may be causing your symptoms. Doctors will often feel your abdomen, the organs in your pelvis, and your rectum.

 

 

Bladder Diary

 

You may be asked to keep a Bladder Diary for a few weeks. With this, you will note how often you go to the bathroom and any time you leak urine. This will help Dr. Tubre learn more about your day-to-day symptoms. The bladder diary helps you track:

 

• When and how much fluid you drink
• When and how much you urinate
• How often you have that “gotta go” urgency feeling
• When and how much urine you may leak

 

Having a Bladder Diary during your first visit can be helpful because it describes your daily habits, your urinary symptoms, and shows Dr. Tubre how they affect your life. Dr. Tubre will use this information to help treat you.

 

 

Other Tests

 

• Urine test: Dr. Tubre may ask you to leave a sample of your urine to test for infection or blood.
• Bladder scan: This type of ultrasound shows how much urine is still in the bladder after you go to the bathroom.
• More tests, like a cystoscopy or urodynamic testing, are usually not needed but may be used if your provider thinks something else is going on.

 

 

Treatment

 

There are a number of things you can do to manage OAB. Everyone has a different experience with what works best. You may try one treatment alone, or several at the same time.

 

You and Dr. Tubre should talk about what you want from treatment and about each option. OAB treatments include:

 

• Medical and Surgical Treatments
• Prescription Drugs
• Bladder Botox® (botulinum toxin) Treatments
• Nerve Stimulation (peripheral and central)
• Surgery

 

 

Lifestyle Changes

 

For OAB treatment, health care providers may first ask a patient to make lifestyle changes. These changes may also be called behavioral therapy. This could mean you eat different foods, change drinking habits, and pre-plan bathroom visits to feel better. Many people find these changes help.

 

Other people need to do more, such as:

 

Limit food and drinks that bother the bladder. There are certain foods and drinks known to irritate the bladder. You can start by avoiding diuretics - these drinks include caffeine and alcohol which encourage your body to make more urine. You can also try taking several foods out of your diet, and then add them back one at a time. This will show you which foods make your symptoms worse, so you can avoid them. You can add fiber to your diet to improve digestion. Oatmeal and whole grains are good. Fresh and dried fruit, vegetables, and beans may help. Many people feel better when they change the way they eat and drink.

 

Some foods and drinks that may affect your bladder:

• Coffee/caffeine
• Tea
• Alcohol
• Soda and other fizzy drinks
• Some citrus fruits
• Tomato-based foods
• Chocolate (not white chocolate)
• Some spicy foods

 

Keep a bladder diary. Writing down when you make trips to the bathroom for a few days can help you understand your body better. This diary may show you things that make symptoms worse. For example, are your symptoms worse after eating or drinking a certain kind of food? Are they worse when you don’t drink enough liquids?

 

Double voiding. This is when you empty your bladder twice. This may be helpful for people who have trouble fully emptying their bladder. After you go to the bathroom, you wait a few seconds and then try again.

 

Delayed voiding. This is when you practice waiting before you go to the bathroom, even when you have to go. At first, you wait just a few minutes. Gradually, you may be able to wait two to three hours at a time. Only try this if Dr. Tubre tells you to. Some people feel worse or have urine leaks when they wait too long to go to the bathroom.

 

Timed urination. This means you follow a daily bathroom schedule. Instead of going when you feel the urge, you go at set times during the day. You and Dr. Tubre will create a reasonable schedule. You may try to go every two to four hours, whether you feel you have to or not. The goal is to prevent that urgent feeling and to regain control.

 

Exercises to relax your bladder muscle.

• Kegel exercises: tightening and holding your pelvic muscles tight, to strengthen the pelvic floor.
• Quick flicks are when you quickly squeeze and relax your pelvic floor muscles over and over again. So, when you feel the urge to go, a number of quick flicks may help control that “gotta go” feeling. It helps to be still, relax and focus on just the exercise. Dr. Tubre or a physical therapist can help you learn these exercises.
• Biofeedback may also help you learn about your bladder. Biofeedback uses computer graphs and sounds to monitor muscle movement. It can help teach you how your pelvic muscles move and how strong they are.

 

 

Medical and Surgical Treatments

 

Prescription Drugs

 

When lifestyle changes aren’t enough, the next step may be to take medicine. Dr. Tubre can tell you about special drugs for OAB.

 

There are several drug types that can relax the bladder muscle. These drugs, like anti-muscarinics and beta-3 agonists, can help stop your bladder from squeezing when it’s not full. Some are taken as pills, by mouth. Others are gels or a sticky transdermal patch to give you the drug through your skin.

 

Anti-muscarinics and betta-3 adrenoceptor agonists can relax the bladder muscle and increase the amount of urine your bladder can hold and empty. Combination drugs, like using both anti-muscarinics and - betta-3 adrenoceptor agonists together may help control OAB when one option alone isn’t working.

 

Dr. Tubre will want to know if the medicine works for you. They will check to see if you get relief or if the drug causes problems, known as side effects. Some people get dry mouth and dry eyes, constipation, or blurred vision. If one drug you try doesn't work, Dr. Tubre may ask you to take different amounts, give you a different one to try, or have you try two types together. Lifestyle changes and medicine at the same time help many people.

 

Bladder Botox Treatment

 

If lifestyle changes and medicine aren’t working, injections may be offered. A trained urologist for men and women, or a female pelvic medicine & reconstructive surgeon (FPMRS) can help with this. They may offer Bladder Botox Treatment.

 

Botox works for the bladder by relaxing the muscle of the bladder wall to reduce urinary urgency and urge incontinence. It can help the bladder muscles from squeezing too much. To put botulinum toxin into the bladder, Dr. Tubre will use a cystoscope passed into the bladder so the doctor can see inside the bladder. Then, the doctor will inject tiny amounts of botulinum toxin into the bladder muscle. This procedure is performed in the office with local anesthesia. The effects of Botox last up to six months. Repeat treatments will be necessary when OAB symptoms return.

 

Dr. Tubre will want to know if the botulinum toxin treatment works for you. They will check to see if you get relief, or if you aren’t holding in too much urine. If urine is not releasing well, you may need to use a catheter temporarily.

 

Nerve Stimulation

 

Another treatment for people who need extra help is nerve stimulation, also called neuromodulation therapy. This type of treatment sends electrical pulses to nerves that share the same path for the bladder. In OAB, the nerve signals between your bladder and brain do not communicate correctly. These electrical pulses help the brain and the nerves to the bladder communicate so the bladder can function properly and improve OAB symptoms.

 

There are two types:

 

Percutaneous tibial nerve stimulation (PTNS). PTNS (peripheral)is a way to correct the nerves in your bladder. PTNS is done by placing a small electrode in your lower leg near your ankle. It sends pulses to the tibial nerve. The tibial nerve runs along your knee to nerves in your lower back. The pulses help control the signals that aren’t working right. Often, patients receive 12 treatments, depending on how it’s working.

 

Sacral neuromodulation (SNS). SNS (central) changes how the sacral nerve works. This nerve carries signals between the spinal cord and the bladder. Its job is to help hold and release urine. In OAB, these nerve signals aren’t doing what they should. SNS uses a bladder pacemaker to control these signals to stop OAB symptoms. SNS is a two-step surgical process. The first step is to implant an electrical wire under the skin in your lower back. This wire is first connected to a handheld pacemaker to send pulses to the sacral nerve. You and Dr. Tubre will test whether or not this pacemaker can help you. If it helps, the second step is to implant a permanent pacemaker that can regulate the nerve rhythm.

 

Bladder Reconstruction/Urinary Diversion Surgery

 

Surgery is only used in very rare and serious cases. There are two types of surgery available. Augmentation cystoplasty enlarges the bladder. Urinary diversion re-routs the flow of urine. There are many risks to these surgeries, so it is offered only when no other option can help.
