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:
- Uroflowmetry: This non-invasive test measures the flow rate and urine pattern during urination.
- Cystometry: This test measures the pressure inside the bladder as it fills and how well it can hold urine.
- Pressure Flow Study: This test measures the pressure in the bladder and urine flow rate while the patient urinates.
- Electromyography: This test records the electrical activity of the muscles and nerves controlling the bladder and urethra.
- 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.
