Urodynamics refers to a group of tests used to assess function of the urinary tract by measuring various aspects of urine storage and evacuation (table 1). Some specific types of urodynamic testing are:

Cystometry (or cystometrogram) evaluates bladder function by measuring pressure and volume of fluid in the bladder during filling, storage, and voiding.

Uroflowmetry measures the rate of urine flow.

Urethral pressure profile tests urethral function.

Leak point pressure determines the bladder or abdominal pressure when leakage occurs due to increased abdominal pressure (Valsalva or cough) to assess urethral resistance.
