Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as: incontinence [1] frequent urination; sudden, strong urges to urinate but nothing comes out; problems starting a urine stream; painful urination
Urodynamic studies are an important component of the evaluation for neurogenic bladder. Urodynamics refers to the measurement of the pressure-volume relationship in the bladder. The bladder usually stores urine at low pressure and urination can be completed without a dramatic pressure rise.
Bladder sphincter dyssynergia (also known as detrusor sphincter dyssynergia (DSD) (the ICS standard terminology agreed 1998) [1] and neurogenic detrusor overactivity (NDO)) is a consequence of a neurological pathology such as spinal injury [2] or multiple sclerosis [3] which disrupts central nervous system regulation of the micturition (urination) reflex resulting in dyscoordination of the ...
A comparative study among patients implanted with different models of artificial urinary sphincter and achieved social continence showed no difference between two groups in regards of urodynamic tests, such as flow rate, urethral pressure, etc. [2] A randomised controlled trial found that the artificial urinary sphincter was non-inferior to the ...
Some studies have led to hypotheses that children with enuresis have altered hemodynamics during sleep (in terms of measurements of blood pressure and heart rate), sleep-disordered breathing, and altered hypothalamus function leading to a lack of bladder control during sleep.
The Journal of Sexual Medicine (JSM) is a peer-reviewed medical journal published on behalf of the International Society for Sexual Medicine. Besides the latter society, it is also an official journal for the International Society for the Study of Women's Sexual Health. The editor-in-chief is John P. Mulhall.
Urodynamics – various techniques measure pressure in the bladder and the flow of urine. People are often asked to keep a diary for a day or more, up to a week, to record the pattern of voiding, noting times and the amounts of urine produced.
Urodynamic testing including Cystometry and Urethral Pressure Profilometry. Women with Fowler's syndrome are often found to have an abnormally elevated urethral pressure profile, increased urethral sphincter volume. [2] [14] The diagnosis is done by testing the Electromyography (EMG) of the external striated urethral sphincter. [citation needed]
