Urodynamic Tests for Urinary Incontinence
Urinary incontinence is a cause of embarrassment for both men and women and present serious social and psychological problems. Incontinence caused by stress and an overactive bladder are the primary causes of this type of problem. Stress incontinence, which is more common in women, causes urine to leak during laughing or coughing. Overactive bladder, also called urge incontinence, is caused by muscle spasms leading to urgent feeling to urinate. The condition can also be caused by a myriad of other reasons such as multiple pregnancies, an overweight condition, and genetic predisposition.
- Patients will be instructed to arrive for the test with a full bladder.
- Urine volume and velocity will be measured while the bladder is emptied.
- A thin, flexible tube called a catheter is inserted into the urethra that leads into the bladder and the volume of any remaining urine is measured.
- The bladder will be flushed with water until a persistent urge to urinate occurs, at which point the volume of water is evaluated.
- A high volume of fluid remains in the bladder after urinating suggesting that the flow of urine out of the bladder is blocked or that the bladder is not contracting enough to force out all the urine out. This condition is known as overflow incontinence.
- The bladder contains fluid volume that is lower or higher than medical norms.
- The patient presents with an inability to retain urine when the bladder contains less than a medically accepted volume.
The renal system plays an important role in the body’s overall health and the urodynamic test is a medical necessity to aid in the diagnosis of incontinence.
