Patients with urological diseases believe that many people have heard of urodynamic tests, but what exactly is urodynamic testing? Why do I need a urodynamic test? But it's not so clear.
When the body's urine is discharged, the flow force and the strength of urination are called urinary power, when your urinary force function is normal, you can ensure that the urine is discharged smoothly from the bladder, otherwise, urine retention or difficulty urinating or urinary incontinence may occur.
Urodynamic testing is a test used to assess bladder function and urine flow. These steps are usually required for this test.
1.Uroflowmetry: Doctors need the patient to urinate in a specific container, and the rate of urine flow is measured to assess how quickly and how strongly the urine is excreted. Urine output, urine flow time, urine flow velocity, and determine the amount of residual urine.
2.Bladder pressure and volume measurement: The doctor will measure the volume of the bladder by measuring the change in pressure inside the bladder, injecting fluid into the bladder, and recording the time point when the patient feels the urge to urinate, and assess the volumetric pressure of injecting and emptying the bladder.
3.Urethral pressure measurement: Doctors measure changes in the pressure inside the urethra to evaluate the function of the urethra, such as the maximum urethral pressure, urethral closing pressure, functional urethral length, and prostatic urethral length.
4.Electromyography: Measure the function of the external sphincter and determine whether the detrusor muscle is in harmony with the sphincter.
With urodynamic testing, doctors can determine how well the bladder stores and voids urine, as well as the ability of the urethra to continuate urinaria.
Assist in diagnosing bladder and prostate diseases, just like some patients, they may have prostatic hyperplasia at this time, the bladder detrusor muscle has weakened contractility, and the doctor can judge whether the patient is bladder outlet obstruction according to the examination results, so as to carry out surgery in time, relieve the problem, save the remaining bladder contractile function in time, and avoid irreversible damage to bladder function.
