When it comes to neurogenic bladder types, understanding the differences is crucial for patients seeking proper treatment and care. Neurogenic bladder refers to a condition where the nerves that control the bladder do not function properly, leading to difficulties in urination. Among the various neurogenic bladder types, the two most common are spastic neurogenic bladder and flaccid neurogenic bladder, each requiring specific management strategies.
This condition can be a result of several neurological disorders, including spinal cord injuries, multiple sclerosis, and other neurological diseases that affect the central nervous system. In this article, we will explore the key differences between spastic and flaccid neurogenic bladder, their causes, symptoms, and available treatment options. We will also share insights from Dr. Bivek Kumar, one of the best urologists in Kolkata at Advanced Urology and Regeneration, to provide expert guidance on managing these conditions.
Understanding Neurogenic Bladder Types
A neurogenic bladder occurs when the nerves responsible for bladder control become damaged or dysfunctional, leading to either overactive or underactive bladder function. The two primary types of neurogenic bladder are:
- Spastic Neurogenic Bladder (Overactive Bladder)
- Flaccid Neurogenic Bladder (Underactive Bladder)
These two types differ in the way the bladder muscles react to nerve signals, which affects urination.
Spastic Neurogenic Bladder: Overview
A spastic neurogenic bladder is a condition where the bladder muscles contract involuntarily due to abnormal nerve signals, leading to frequent, urgent, and sometimes painful urination. This type of bladder is often associated with neurological disorders that affect the upper motor neurons — the part of the nervous system responsible for sending signals to the bladder muscles. Conditions like spinal cord injuries, multiple sclerosis, or brain injuries can lead to spastic neurogenic bladder.
Key Features of Spastic Neurogenic Bladder:
- Overactive Bladder Muscles: The bladder contracts too frequently or strongly, causing an urgent need to urinate.
- Involuntary Bladder Contractions: These contractions occur even when the bladder is not full.
- Increased Frequency: Patients may experience frequent urination, sometimes as many as 20-30 times per day.
- Urge Incontinence: Sudden, uncontrollable leakage of urine.
Symptoms:
- Frequent urge to urinate
- Painful urination
- Incontinence (involuntary urine leakage)
- Nocturia (waking up frequently at night to urinate)
Causes of Spastic Neurogenic Bladder:
- Spinal Cord Injuries: Damage to the spinal cord above the sacral region can cause abnormal bladder contractions.
- Multiple Sclerosis: MS can disrupt nerve communication between the bladder and the brain.
- Cerebrovascular Accidents (Stroke): A stroke can damage parts of the brain that control bladder function.
Flaccid Neurogenic Bladder: Overview
In contrast to the spastic type, a flaccid neurogenic bladder occurs when there is insufficient bladder muscle contraction due to damaged lower motor neurons. This type of bladder is commonly linked to conditions affecting the spinal cord or peripheral nerves, such as cauda equina syndrome, diabetic neuropathy, or spinal cord injury at the sacral level.
Key Features of Flaccid Neurogenic Bladder:
- Weak or Absent Contractions: The bladder fails to contract effectively to expel urine, leading to urinary retention.
- Urinary Retention: Patients may be unable to fully empty their bladder, leading to the need for intermittent catheterization.
- Overflow Incontinence: When the bladder becomes overly full, small amounts of urine leak out due to the pressure.
Symptoms:
- Difficulty starting urination
- Dribbling urine
- Full bladder sensation without the urge to urinate
- Chronic urinary retention leading to bladder distension
Causes of Flaccid Neurogenic Bladder:
- Spinal Cord Injuries: Damage to the lower part of the spinal cord can result in flaccid bladder dysfunction.
- Peripheral Neuropathy: Damage to the nerves outside the spinal cord, often seen in diabetic neuropathy, can interfere with bladder function.
- Cauda Equina Syndrome: Compression of the nerves at the base of the spinal cord can lead to flaccid bladder.
Spastic vs. Flaccid Neurogenic Bladder: Key Differences
Aspect | Spastic Neurogenic Bladder | Flaccid Neurogenic Bladder |
Bladder Muscle Activity | Overactive, involuntary contractions | Underactive or absent contractions |
Urination Frequency | Increased frequency, urge incontinence | Decreased frequency, urinary retention |
Bladder Control | Poor control, frequent leakage | Poor control, difficulty initiating urination |
Cause | Upper motor neuron injury (e.g., stroke, MS) | Lower motor neuron injury (e.g., SCI, neuropathy) |
Treatment Options | Anticholinergic drugs, Botox, bladder training | Intermittent catheterization, medication for retention |
Diagnosis and Treatment Options
Both spastic and flaccid neurogenic bladder require an accurate diagnosis to determine the appropriate treatment. A healthcare professional, such as Dr. Bivek Kumar, a leading urologist at Advanced Urology and Regeneration, will evaluate the patient’s medical history, symptoms, and may conduct tests such as:
- Urodynamic Studies: To assess bladder pressure, volume, and muscle function.
- Cystoscopy: To look inside the bladder for signs of injury or disease.
- Neurological Examination: To determine the extent of nerve damage.
Treatment for Spastic Neurogenic Bladder:
- Medications: Anticholinergics like oxybutynin or tolterodine can help reduce bladder spasms.
- Botox Injections: Botox can relax bladder muscles and reduce overactivity.
- Bladder Training: Techniques to help retrain the bladder and improve voiding patterns.
- Surgical Options: In severe cases, surgery such as sphincterotomy or bladder augmentation may be considered.
Treatment for Flaccid Neurogenic Bladder:
- Intermittent Catheterization: The patient may need to use a catheter to empty the bladder regularly.
- Medications: Alpha-blockers like tamsulosin can help improve bladder emptying.
- Surgical Options: In cases of severe retention, bladder augmentation or the creation of a neobladder may be considered.
Why Early Diagnosis is Essential
Both spastic and flaccid neurogenic bladders can lead to serious complications if left untreated, such as urinary tract infections, kidney damage, and urinary incontinence. Therefore, it’s crucial to seek treatment as early as possible. Dr. Bivek Kumar, at Advanced Urology and Regeneration, offers personalized treatment plans to manage and improve bladder function for patients with neurogenic bladder types.

Understanding the differences between spastic and flaccid neurogenic bladder types is essential for effective diagnosis and management. By working with a knowledgeable urologist, such as Dr. Bivek Kumar, and following the appropriate treatment options, patients can regain control over their bladder function and improve their quality of life.
