Your bladder, located in your lower abdomen, stores urine produced by your kidneys. When it fills up, it sends signals through your nerves to alert your brain that it's time to empty it. These signals trigger your bladder to contract, allowing urine to pass through the urethra. This communication between your bladder and brain ensures everything works smoothly, keeping your body's processes in sync.
Neurogenic bladder develops when the communication between your brain, nerves, and bladder no longer functions properly.
What Does Neurogenic Mean?
The term 'neurogenic' means issues that arise from the nervous system.
A neurogenic bladder occurs when your brain, spinal cord, and bladder no longer communicate properly. This miscommunication can cause your bladder to:
- Overact by contracting too often or unpredictably
- Underact, failing to empty fully or at all
What Causes Neurogenic Bladder?
Neurogenic bladder often develops from conditions that damage the nerves controlling the bladder. These include:
- Spinal cord injuries
- Multiple sclerosis
- Stroke
- Parkinson's disease
Diabetes
Some people can also be born with structural or nerve issues affecting the bladder, such as:
- Spina bifida, which is an incomplete development of the spine
- Sacral agenesis, where parts of the spine are missing
Common Symptoms of Neurogenic Bladder
A neurogenic bladder can be unpredictable and disruptive. It often interferes with your routines and activities. Symptoms of this condition may include:
- Frequent urination of more than eight times a day
- Sudden, urgent urges to urinate
- Urine leakage during physical activity or even rest
- Difficulty starting or fully emptying your bladder
- Urinary retention
- Painful urination, which may indicate infection or irritation
How is Neurogenic Bladder Diagnosed?
Diagnosing a neurogenic bladder often involves several tests. They help your doctor evaluate your bladder's function and find the cause of your symptoms. Tools your doctor may use to diagnose this condition include:
- Urodynamic tests. These tests assess how your bladder holds and empties urine. Sensors can also be placed near the rectum or urethra to measure nerve and muscle activity.
- Cystoscopy. This procedure uses a thin tube with a camera to inspect your bladder and urethra visually for abnormalities.
- Imaging. Ultrasound, MRI, or CT scans can be utilized to obtain a detailed view of your bladder, kidneys, and the surrounding abdominal areas.
Treatment Options for Neurogenic Bladder
Managing a neurogenic bladder can often require a mix of lifestyle changes and medical treatments chosen to meet your specific needs. Examples of effective interventions include:
1. Dietary changes
- Avoiding bladder irritants like caffeine, alcohol, and acidic foods
- Staying hydrated and managing constipation to reduce bladder pressure
- If diabetes is a factor, controlling blood sugar levels to minimize nerve damage
2. Bladder retraining
Bladder retraining means slowly increasing the time between bathroom trips. This helps your bladder hold urine better. Following a scheduled voiding routine can make this process more effective.
3. Catheterization
Catheterization may be performed to alleviate urinary retention and comes in two main types:
Intermittent catheterization: a catheter is inserted as needed to empty the bladder and then removed
Continuous catheterization: a catheter remains in place for constant drainage
4. Medications
Medications are prescribed to manage various symptoms. Depending on your needs, these medications may:
- Relax bladder muscles. Drugs such as anticholinergics or beta-3 agonists help calm overactive bladder muscles. This reduces the sense of urgency and frequent trips to the bathroom.
- Stimulate bladder contractions. Medications like cholinergic agents can promote stronger bladder contractions. They help to improve emptying for those with weak bladder function.
5. Botox injections
Botulinum toxin (Botox) injections effectively relax the bladder muscles. Botox minimizes involuntary contractions, decreasing symptoms such as urgency, frequency, and incontinence. The effects of these injections last about six months, after which the procedure can be repeated to maintain symptom relief.
6. Neuromodulation
Neuromodulation therapies stimulate bladder-control nerves. They improve communication between the brain and bladder by "resetting" the nerves. Two techniques for managing symptoms are:
- Sacral neuromodulation. This involves implanting a small device under the skin near the lower back to stimulate the sacral nerves, which play a key role in bladder control. An example is InterStim.
- Percutaneous tibial nerve stimulation. This is a less invasive option. It involves inserting a thin needle near the ankle to stimulate the tibial nerve. This indirectly influences bladder function. An example is NURO PTNM.
8. Surgical options
When other treatments are ineffective, surgery may be considered. Common surgical options include:
- Bladder augmentation. Increases the bladder's capacity by using a piece of the intestine to expand the bladder wall.
- Urinary diversion. In cases where the bladder cannot function properly, a new pathway is created for urine to exit the body.
Are There Consequences to Unmanaged Neurogenic Bladder?
If neurogenic bladder isn't correctly managed, it can lead to more serious or complex health issues over time, including:
- Urinary tract infections. If the bladder doesn't empty completely, urine can stagnate, providing a breeding ground for bacteria.
- Bladder stones. Retained urine can lead to the buildup of minerals, which may crystallize into stones that cause problems like pain and blockages.
- Kidney damage. High pressure in the bladder can force urine to flow back into the kidneys, harming kidney function.
If you have neurogenic bladder symptoms, it's time to see an experienced urologist. They can find solutions and help prevent complications.
FAQs
1. Can neurogenic bladder be managed without surgery?
Most people find relief with lifestyle changes, medications, and if needed, catheterization. Surgery is usually a last resort.
2. Will my symptoms worsen over time?
Symptom progression depends on the underlying cause. Regular follow-ups with your doctor can help monitor changes and adjust your treatment plan.
