Interpretation of Urodynamics consists of the 3 C’s and 2 S’s. The 3 C refers to the sphincter’s Capacity, Compliance, and Competence. The 2 S’s refer to Sensation and Stability.

Bladder capacity is studied to determine the amount of fluid the bladder holds. Compliance is the ability of the bladder wall to distend. The relationship between change in the bladder volume and change in the detrusor pressure is measured. The EFP or (End Filling Pressure) should be below 15cnH20. The EFP (End Filling Pressure) of 40cmH20 or greater may lead to high risk to the upper tract. The competence of the sphincter is the ability of the external striated muscle to hold urine and to relax and release urine. This can be evaluated by using VLPP (Valsalva Leak Point Pressure). The VLPP is automatically marked and calculated with a simple keystroke.

Sensations of the patient are recorded during the filling phase. Volume, pressures, and psychosocial environment affect a patient’s feelings. According to ICS, Morpheus® has conveniently placed study markers to indicate these sensations.

Stability refers to the detrusor function during filling. Normal detrusor function allows bladder filling with little or no change in pressure. Detrusor overactivity is a urodynamic observation characterized by involuntary detrusor contractions during the filling phase, which may be spontaneous or provoked. Convenient study markers are easily placed during the study with a click of a button or tap of the touch screen.

Urodynamics is the study of the function and dysfunction of the lower urinary tract, which includes the bladder, urethra, and the muscles and nerves involved in urine storage and release. It involves a series of tests that measure the efficiency of the bladder and urethra in storing and expelling urine. These tests help medical professionals diagnose urinary incontinence, voiding difficulties, and other lower urinary tract problems.

Urodynamic tests may include:

1. Uroflowmetry: This non-invasive test measures the flow rate and urine pattern during urination.
2. Cystometry: This test measures the pressure inside the bladder as it fills and how well it can hold urine.
3. Pressure Flow Study: This test measures the pressure in the bladder and urine flow rate while the patient urinates.
4. Electromyography: This test records the electrical activity of the muscles and nerves controlling the bladder and urethra.
5. Video Urodynamic Tests involve X-ray or ultrasound imaging to visualize the bladder and urethra during filling and emptying.

Urodynamic testing can help determine the cause of urinary problems and guide the appropriate treatment plan for patients.
