Urodynamic testing is a test to know how the lower urinary tract is functioning, that is, how urine is stored and eliminated. It is used to diagnose pathologies such as urinary incontinence, neurological diseases that affect the urinary tract, urinary tract infections, etc. The test consists of several parts. First, the patient must urinate in a container called a flow meter, which allows measuring the amount and speed of urine. A probe is then placed through the urethra with the aid of an anaesthetic gel that reaches the bladder and is used to measure its pressure and fill it with sterile saline solution. Finally, the patient must urinate with the probe placed, which is then removed. It is a simple procedure that takes about 30 minutes.
