Urodynamic Study Functional study of the lower urinary tract

The urodynamic study is an urological test that evaluates the behavior and functioning of the bladder, during the filling and emptying phases, also evaluating the function of the urinary sphincter.

It is indicated for patients with urinary symptoms and urinary incontinence refractory to treatment, for evaluation of patients with neurological diseases or to better characterize the pathology of patients prior to urological surgical procedures.

It is an exam lasting 30 to 60 minutes long and is painless. It consists of introducing one catheter into the bladder through the urethra and another catheter into the rectum. These are probes with sensors that measure pressure.

The examination is divided into 3 components: the first consists of a slow bladder filling phase with saline solution (through a bladder catheter), and the concomitant assessment of intravesical pressure (through a pressure transducer in the same bladder catheter) and intra-abdominal (intrarectal balloon catheter) and measurement of a possible urinary flow (urofluxometer); then pressure / flow curves, ie, the relationship between intravesical pressures and urinary flow, are obtained during a voiding phase (where the patient is urged to urinate); the third component, urethral profilometry, enables the closure pressure of the urethral sphincter to be assessed through a transducer placed at the end of a catheter that traverses the urethra as it is collected.

The Urodynamic Study will always be performed by a Urologist doctor experienced in functional Urology and in the medical and surgical treatment of the associated pathologies, which gives him the best sensitivity for his correct evaluation.
