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
The primary results of cystometric analysis is the cystometrogram. The x-axis is the volume of liquid and the y-axis is the intraluminal pressure of the bladder. In normal patients, the plot is a series of spikes whose local minimums form a non-linear curve resembling an exponential growth curve.
A uroflometer for measuring urine flow. Urine flow rate or urinary flow rate is the volumetric flow rate of urine during urination.It is a measure of the quantity of urine excreted in a specified period of time (per second or per minute).
Common findings, determined by ultrasound of the bladder, include a slow rate of flow, intermittent flow, and a large amount of urine retained in the bladder after urination. A normal test result should be 20–25 ml/s peak flow rate. A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for ...
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

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.
