Needing to go back a second time shortly after passing urine to pass more urine.Feeling like the bladder has not emptied completely.Needing to push and strain to empty the bladder.Symptoms of detrusor underactivity (or an underactive bladder), include: Urge urinary incontinence – leakage of urine on the way to the toilet usually associated with a feeling of urgency.Nocturia – going often to pass urine at night.Problems with detrusor overactivity can cause symptoms of: This is the reason why a urodynamic study is crucial in providing information about the specific type of neurogenic bladder present in an individual patient’s neurological condition. “The bladder is an unreliable witness” is an expression used to indicate that bladder symptoms do not give a specific diagnosis especially when it comes to the complex abnormalities of bladder function and malfunction that occur with neurological conditions. Additionally the effects of a neurological condition can result in changes in bladder and urethral function over time. Symptoms of different patterns of bladder abnormality also overlap. Each neurological condition can also cause marked variation in the “type “ of neurogenic bladder that occurs. The symptoms of neurological problems affecting the urinary tract are highly variable and do not necessarily correlate with a specific neurological problem.
What symptoms can a Neurogenic Bladder cause? Treatment is then directed at issues of urinary storage and of urinary emptying.
Underactive detrusor with normal urethral sphincter.Underactive detrusor with underactive urethral sphincter.Underactive detrusor with overactive urethral sphincter.Overactive detrusor with normal urethral sphincter.Overactive detrusor with underactive urethral sphincter.Overactive detrusor with overactive urethral sphincter.The EAU (European Association of Urology) - Madersbacher classification system classifies neurogenic bladder issues as follows: The classification system divides function of the bladder (or detrusor muscle) and the sphincter into overactive, underactive or “normo-active” (i.e. One of the classification systems used for neurological bladder disorders looks separately at the abnormality of the bladder and the urethral sphincter (on/ off valve that sits below the bladder in the urethra and prevents urine leakage). Any interruption in these complex nerve pathways transmitting messages to and from the bladder and urethra may result in a neurogenic bladder. Good bladder function depends on normal nerve signals at all neurological levels from the brain, spinal cord and in the peripheral nerves. Any abnormality in the nerve supply to the bladder can result in abnormal bladder function. The bladder and urethra require a normal nerve supply in order to function properly. General conditions that can affect nerve function at multiple levels.Some of the many potential causes of a neurogenic bladder include: What are the causes of a Neurogenic Bladder? the brain, spinal cord, peripheral nerves) can affect the function of the lower urinary tract. Abnormalities at any level of the nervous system (i.e. Abnormalities of nerve supply can affect both the bladder and the urinary sphincter (the urinary control mechanism or valve located in the urethra). A neurogenic bladder is a bladder with an abnormal nerve supply.
