Voiding dysfunction is a broad term, used to describe conditions where there is poor coordination between the bladder muscle and the urethra. This results in incomplete relaxation or overactivity of the pelvic floor muscles during voiding.
Voiding dysfunction occurs when there are abnormalities in filling, storage and emptying of urine. Voiding dysfunction is often described by symptoms such as frequency (urinating more than 8 times per day), urgency (strong need to urinate) and urine retention (unable to empty your bladder).
A timed voiding schedule is an important part of bladder retraining. Biofeedback and Kegel exercises (pelvic floor relaxation and contraction) can also effectively help manage dysfunctional voiding. The physician may also be prescribed medicine that helps the bladder relax.
A voiding dysfunction is typically caused by over-active pelvic floor muscles. Other possible causes include nerve problems affecting the way bladder muscles contract and blockages within the tube that takes urine out of the body (urethra).
Incomplete bladder emptying is most commonly described and measured as the volume of urine left in the bladder after voiding, also known as the postvoid residual. The two common causes of CUR are bladder muscle dysfunction (detrusor underactivity) and obstruction.
Medications: Several medications improve voiding problems. Alpha blockers such as tamsulosin (Flomax®) may help. Or you may try drugs for overactive bladder, such as oxybutynin (Ditropan®) and tolterodine (Detrol®) if you have bad urinary urgency or leakage.
The condition may be caused by a birth defect, usually one involving the spinal cord, or it may be acquired as the result of a different problem. While neurogenic bladder can't be cured, necessarily, it can most definitely be managed.
Of the three factors studied (menopause, age, and parity), only parity had a significant impact on uroflowmetry and pressure-flow study results (Qmax, p=0.007; PVR, p<0.001; Qmax.
Urinary retention is a condition in which you cannot empty all the urine from your bladder. Urinary retention can be acute—a sudden inability to urinate, or chronic—a gradual inability to completely empty the bladder of urine.
Urination is the process of excreting urine from the urinary bladder. This is also known as the voiding phase of micturition. Most of the time, the bladder (detrusor muscle) is used to store urine.
Voiding dysfunctions are conditions that affect the ability of the body to urinate normally. People with a voiding dysfunction may urinate when they don't intend to (like when laughing or coughing). They may also find that they urinate too often, too infrequently or with pain.
A VCUG, or a voiding cystourethrogram, is a minimally invasive test that uses a special x-ray technology called fluoroscopy to visualize your child's urinary tract and bladder. A VCUG can help: diagnose vesicoureteral reflux, a condition in which urine flows the wrong way, from the bladder back up to the kidneys.
Voiding symptoms, which are caused by lower urinary tract obstruction, include slow stream, splitting or spraying, intermittency, hesitancy, straining, and terminal dribble.
Urodynamic testing, including electromyography, looks at how well parts of the urinary tract—the bladder, urethra, and sphincters—are storing and releasing urine. Cystoscopy is a procedure that uses a cystoscope—a long, thin instrument—to look inside the urethra and bladder.
Why Your Bladder and Kidneys Need Water. As mentioned above, water helps to flush out the urinary tract, keeping everything in working order. If we don't drink enough fluids, we become dehydrated, which results in concentrated urine and reduced urine output.
In other people with a painful bladder, the production of a more concentrated urine may be irritating to the bladder. In these patients, drinking more water can help incontinence due to decrease in the frequency of voiding and the amount of leakage.
For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times a day can also be normal if that person is healthy and happy with the number of times they visit the toilet.
If you're not emptying your bladder completely, you might feel the urge to void often but have hesitancy when you try to void. You may also wake up at night often to void since the bladder is not completely empty during the day.
In the practice of physical medicine and rehabilitation, voiding disorders are usually a result of neurologic conditions, such as spinal cord injury (SCI) or disease, cerebrovascular accident (CVA), traumatic brain injury (TBI), multiple sclerosis (MS), or dementia.
Monosymptomatic enuresis is the most common voiding disorder encountered by pediatricians. It is diagnosed in children older than 5 years without any other lower urinary tract symptoms.
The parasympathetic nervous system stimulates the muscarinic stretch receptors in the bladder through the pelvic nerve fibers. When urine fills the bladder, the M3 receptors located within the bladder become stretched and stimulated, which leads to the contraction of the detrusor muscle for urination.
If you've been diagnosed with urge incontinence, one of the first treatments you may be offered is bladder training. Bladder training may also be combined with pelvic floor muscle training if you have mixed urinary incontinence.
