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
To empty the bladder regularly, clean intermittent catheterization (CIC) can be used. If the urodynamic study shows non-inhibited detrusor contractions, an anticholinergic drug should be given additionally. To prevent recurrent infections, especially in the case of vesicoureteral reflux, the treatment can also include an antibiotic prophylaxis.
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.
The medical school environment may also be a factor. A study in 2012 also showed after an analysis of match rates from schools between 2005 and 2009 that 20 schools sent more than 15 students into urology (1 standard deviation above the median), with Northwestern University sending 44 students over those five years.

JAMA Pediatrics is a monthly peer-reviewed medical journal published by the American Medical Association. [1] It covers all aspects of pediatrics.The journal was established in 1911 as the American Journal of Diseases of Children and renamed in 1994 to Archives of Pediatrics & Adolescent Medicine, before obtaining its current title in 2013.
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 ...
In voluntary urination, the bladder's normally relaxed detrusor muscle contracts to squeeze urine from the bladder. One study, of 109 children diagnosed with giggle incontinence at Schneider Children's Hospital in New York, concluded that the cause of giggle incontinence is involuntary contraction of the detrusor muscle induced by laughter.

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.
