The resulting chart generated from cystometric analysis is known as a cystometrogram (CMG), which plots intravesical pressure against the volume of fluid in the bladder.

[1][2] Cystometric analysis is used to evaluate the bladder's capacity to contract and expel urine.

It is used as a component for diagnosis of various disorders including urinary tract infections, multiple sclerosis, stroke, spinal cord injury, urethral obstruction, and overactive bladder, among others.

In normal patients, the first couple hundred milliliters of urine flow with minimal applied pressure.

There is also the potential for trauma to the bladder and urethra, which may result in hematuria (blood in the urine).
