urodynamics

 [u″ro-di-nam´iks]
the dynamics of the propulsion and flow of urine in the urinary tract. adj., adj urodynam´ic.



Urodynamic testing is done by injecting water or carbon dioxide into the bladder via a catheter. Bladder sensation, capacity, and strength of contraction, as well as ability to hold urine in the bladder, can thus be quantified.

urodynamics

Functioning of the urinary bladder, urethral sphincter and pelvic floor muscles. Urodynamic studies, which may be made in various ways, involve measurement, over a period, of such parameters as urine flow rates; total bladder capacity; bladder urine volume before voiding; residual urine volume; bladder pressure before and during voiding; bladder contractability; urethral sphincter pressure; patient's perception of bladder fullness; and ability to inhibit voiding. Urodynamics has been described as the ‘gold standard investigation’ in the management of all forms of urinary incontinence.
